Going by a lot of the comments, I don't think most of your half wit viewers understood a word you said about how throttle controllers work. Think you may need to dumb down. A 100% throttle is the same with or without the controller, all a controller does is change the electrical curve between 0 to 100% input, instantly jamming your foot to the board is an all but identical outcome in both situations.

I’ve found that the best way to overcome any noticeable boost threshold when setting off at lights is to accelerate smoothly and not to treat every set of lights as the starting grid of the eastern creek drag strip. As my dad often said “it’s not a race”.

@@Low760 in suburban traffic what are you doing “having to pull out past a slower car”? Surely there is risks to that behaviour and ultimately it may be your patience that has too much boost going on? I watched a dick hammer past me towing a camper in an 80 section, down to 60 and lots of traffic. He probably changed lanes 30 times in the space of 12kms and I was keeping up with him sitting in the one lane taking off gently? Plenty of brake distance between me and other cars and yet when we got to the start of the next 80 section he was behind me. It was hilarious and his poor car!

I know a guy who drives at 90 on the highway every day on his way to work. He does it to save fuel. He also carries a whole fitted out camper, roof basket with compulsory recovery tools, shovels, those plastic grip things, a steel bullbar, winch, water tanks, two fridges on the back seat full of water and drinks... he's loaded the buggery out of the poor ute. However, upon forum advice, beard-stroker encouragement, and dealer recommendations - he has had an oil catch can and snorkel fitted, and wider tyres (sadly, the new tyres have a lower load rating so that's not brilliant) on new wheels. This was going to magically reduce his fuel consumption by at least 15%, somehow... he also wants to upgrade the air cleaner system, as that's going to destroy his engine if he continues to drive on the highway - according to the dealer. Oh, he uses the camper one weekend a year, so it's just too inconvenient to take it off when he's not using it.

When i bought my first Land Rover Defender it had 265x16 tyres on it. It was slow and the fuel economy was bad. I did a bit of reading online and read a comment about with the bigger tyres fitted it brought the engine revs down to under peak boost so you always used wider throttle opening to maintain speed. When the tread wore down a bit i swapped them for a set of 235x16s. The revs a cruising speed then sat on boost. I drove using less right foot to maintain cruising speed, economy went up and it was more responsive too.

Thanks John. Informative and entertaining (no surprise there). I do have a EVC throttle controller on a 2.2 liter diesel 2017 Ford Ranger (European specs). I tried the available settings the first day, with this results: - Making the pedal ramp steeper at the beginning (U settings): basically useless. - Making the pedal ramp less steep at the beginning (E settings): useful while rock crawling. It gives me more control (more pedal movement to achieve the same torque increase). I identified E4 as the right setting for me. It turns out it's good on gravel and unpaved roads too. - Auto position: mostly harmless (but funny) on paved roads, no-no on unpaved roads or rocks. So I basically set it to AC on paved roads and E4 elsewhere. I have never driven on sand, so I have no idea what the useful setting would be, if any. My general experience: - Useful? Yes, off road (period). I think it's worth its cost. - Could I live without? Yes, absolutely (I actually did, before buying it). - Would I buy it again? Probably yes, for another 4x4 vehicle and only to reduce the pedal response.

Yeah this is where the Kakadu shines because it has that switch to change between driving modes which just adjust the throttle response. On the streets, use “sport” (or whatever it is, I don’t have a Kakadu) and that response lag is vastly reduced. Over at the other extreme is “rocks” which dulls the response to a mere politely whispered suggestion so when bouncing around over rocks your throttle is kept steady despite what your foot is doing.

Throttle controllers adjust the responsiveness of the throttle, which does have its advantages, because sliding backwards downhill for an extra 2 seconds while the computer figures out that "foot to the floor" equals "FUCKING MOVE IT" can be dangerous off-roading. You also have the benefit of making the throttle less sensitive for rock-crawling and taking off in soft sand. John, you've also made points about how vehicle manufacturers have to cater for different application, so there will always be compromises if the way you use a vehicle falls outside of their setup, so writing off the entire after-market business is the wrong move to make. You are 100% correct though stating that you need to find out what needs to be improved first before splashing the cash.

I will be investing in an EVC throttle controller because many more credible sources who have actually tested them say they work very well. And they do in effect reduce turbo lag by getting the engine revs up to the boost threshold quicker. They are also useful for manual transmission 4WDs to soften the throttle response in "crawling" mode. Mr Cadogan gives a good explanation of selected theories, but needs to test products before canning them. I'd suggest the hatred of "beard strokers" is clouding the judgement? 😉

Ive got a 2016 Patrol - i bought it during lockdown from a guy in Victoria sight unseen (but inspected) . He'd installed a throttle controller (and everything else for excursions up dp creek) . Its a bit more nuanced than John has explained - it does make the vehicle more responsive (not more powerful, not less laggy) - but more interesting to me are the other options - i can turn down the throttle response - great for wet weather driving and when you dont want a jumpy 4x4 in tricky offroad conditions - and theres an auto option that feels more engaging with how im driving at any time (it gets punchier if i put my foot down, yet more sedate with a lighter foot). Turning it off always feels like the Troll is falling asleep.

Great Video John. I have Been building and Modifying Car Turbochargers professionally for over 30 years. The common request from diesel 4x4 owners is for less Turbo Lag. They do mean "boost threshold" but this is not in their grasp of technical understanding terms to describe something in a turbo engine. When I am asked to "Upgrade" or "high flow" a turbo for more power, the general customer does not like to here that increasing component internal part size to increase flow will result in a worse boost threshold ("lag" in their language). It needs to be explained to the customer that any modification to increase flow has a pay off in the performance of a turbo engine. They also hear results from tuning upgrades, that increasing fuel at a lower RPM to lower boost starting point in the revs help performance but this also has a pay off in fuel economy and extra heat from the increased fuel. I think the modifying Turbocharger industry would be the most misinformed, misunderstood, highly technical, and super competitive and riskiest engine porformance upgrades in the Aftermarket industry.

When turbos reached their peak in the F1, turbo lag was loosely defined as the number of laps from when the first turbo car passed the finish to when the first non-turbo car passed the line. Loved that anecdote. Built my first turbo car in in 1981, and it had a split pulse manifold and dual scroll turbine and there was no discernable 'lag'. My current car Lancer Ralliart has a single scroll turbine and there is noticeable lag - in comparison. The EVO uses a split scroll design to help overcome this. Turbochargers by Hugh MacIness is a great reference.

For 5 and a half years I've been cussing out my Tucson turbo diesel for the exact scenario you described, convinced it was a fault. I have just apologized to my trusty steed for being ignorant of the facts. Thank you for your explanation. I'm less dumb now than I was previously.

John I find throttle controllers improve the driving experience. My wife and others have a view that the immediacy of throttle response provided is too much for them. 3 turbo Subarus, 2 atmo Subarus and one turbo BMW and I will always use a throttle controller as the driving experience is improved for me. On a track that has corners the improvement is noticeable with better punch out of corners and lower lap times. On a straight there is no change. I use hikeit brand and have a great experience and recommend to anyone that wants to improve the driving experience.

I bought a car with one fitted, got sick of tuning it up and down. Ditched it and let the factory tune do it’s thing. Much happier

Well, 2015 MN Triton with the 4D56 "HP" 2.5L, we have had a throttle controller for 3 years now.. all it does is compress the throttle bandwidth, (and helps kill engine mounts) the Triton is great and goes really well on boost, if you loose that boost or miss a shift, it's a dog and there is no throttle controller that can fix that.

Thanks for another great answer to a common question. My turbo diesel doesn't suffer from limp dick (aka turbo lag) because it's a.....class leading Kia 2.2, 4 cylinder, common rail, direct injection turbo diesel. It has similar max power and torque as the Toyota 70 series 4.5 litre V8 turbo diesel without the thirst. If I nail it from a standing start it will spin the front wheels until the traction control cuts power. It has seamless power and acceleration, so if Kia can tine it to perform without lag, so could other makers? I will confess to towing an aluminium clad, acoustically transparent, shitoure and a dual axle garden maintenance trailer around Australia for more that 1/4 of it's almost faultless 240,000 kms in 8 years, but haven't found Dingo Piss Creek.

I looked into the throttle controllers and found exactly what you said JC, it's just changing the throttle pedal's setting, essentially lying to the car's ECU. I've read of people going and getting their car's tune/map updated and these controllers became a problem because they're designed to account for factory maps.

My turbocharged Noble has a throttle controller. It's my right foot. The cable between the pedal and the butterfly enables amazing control over engine behavior.

Problem with turbos is that most people think its 1985 when it comes to 'turbo lag' and having driven the lunacy back then compared to the modern day turbo's is night and day. Technology and efficiency has made most of the ones fitted up to cars, trucks and 4wds very well tuned for the average dude's vehicle and its engine size, they've got really good flow rates, matches to the exhaust output, your rev range and the engines peak torque. Much science and big thinks go into them straight out of the factory to make them very good Of course, you can go the tuning route on them but I think on a new car its honestly a waste of money and you may as well burn the warranty because it'll be worth sweet-fa.

I usually only rely on anecdotal evidence. My 2.0 turbo ute had dreadful throttle delay, as in 3 to 4 seconds, and the accelerator pedal failed completely at 40k and was replaced under warranty. New pedal was a touch better but still bad. My wife hated driving it. At 60k I installed an IVC controller and fixed the issue. I run it in 'auto' mode around town and use hi in sand and dumb it down for the slow and steep rock climbs. I test it every now and then by switching it off and all the problems come back. I'm not sure whether my diesel 2.0l just loosened up a bit or or the IVC is responsible but my fuel consumption went from exactly 10 litres per100km down to an average of 8.75. It is much nicer to drive in all conditions and it appears to be saving me some fuel costs as well. My wife is very happy to drive it now as well! Best money I have ever spent on a vehicle! PS I use 4wd every day for work but I have no aspirations for Dingo Piss Creek. Cheers

I have learnt a new thing today. I've recently bought an MG HS and when I press the gas it takes a second to respond and I used to think its turbo lag

Yeah people are confusing "turbo lag" with e-throttle response times. I have a 4D56 challenger, and the throttle response is often terrible. In the time it takes to stab the throttle flat to the floor, and lift off again, the engine has barely come up from idle. Also I've never been able to smoothly double clutch a downshift yet. It's not turbo lag.

My missus had a vw golf with the 1.4 tsi petrol supercharged and turbo tickover to redline power all way through

What I'd like to know, what is the difference between "removing" boost threshold with a throttle controller and just blipping the throttle to spin up the turbo when you see the lights changing and pulling away as normal? If you want instant throttle response, don't get a turbo but you will miss out on all those efficiency gains when the engine isn't under load.

I've found the ability to adjust throttle response with a throttle controller to be very advantageous. In slick conditions I can numb it down and enjoy a crisper throttle when desired. There are several videos that have actually shown the benefit in quicker times with a throttle controller. I myself don't care about the quicker times as I don't drag race my cars, but I do love the feeling of the throttle response being what I want it to feel like.

Exactly for this, because I don't like the rubbery response of the engine to the request of the gas pedal...and when you change gear, you're chasing thrust again...I bought a petrol 2,5L non-turbo Mazda

Thinking of getting a Pedal Box for my EV as the snorkel did bugger all for the turbo lag.

If you view the the torque demand signal to actual torque as a linear system, you could in fact subtract the turbo lag by applying the inverse filter. In practice it doesn't work as the engine is a non linear system, meaning you can't just put more fuel in the diesel at a certain rpm and expect respective torque increase, the torque will saturate. And likely the filtering of the accelerator pedal signal in the engine controller is also non linear, for emissions, for safety, longevity, comfort, etc.

The words bullshit and aftermarket 4x4 accessories were just made for each other, like a jock in a sock. But it's made some guys rich, so not all bad.

Thank You, I have to explain this to customers at my auto shop often. Opening the throttle too far too soon actually reduces engine performance.

Properly sorted R and D is what matters my VW Touareg V6 Turbo Diesel has no turbo lag, and economy is excellent .

You forgot to mention the extra 40 hp and way better fuel economy that a throttle controller gives . Pull one apart and have a look inside , they are full of oil . Snake oil .

John’s right don’t waste ur money on a throttle controller I had a dpchip on a single turbo diesel no good ended up buying a Biturbo diesel great response 😎

I've got a HikeIt throttle controller on a Toyota. It's permanently set on sport 4. That's about the middle of the range setting between off and Race 9 setting. It makes the throttle respond like most drivers would remember when the throttle had a real cable connecting your foot to the carburettor /throttle body. Otherwise it has no effect on anything.

Possibly but I'd fit a pressure bottle plumbed into intake line and activated by something like a kickdown switch.. So it dumps pressure into the intake aft of the turbo to provide pressure until the turbo spools..

The Reynolds number is a harsh mistress

XM Sorento CRDI. 580,000km. The evc does change the way the vehicle drives. As the engine has a variable geometry turbo ( electrically controlled ) I believe the evc changes the ramp speed of the throttle which affects both fuel injection and the turbo.

Throttle controllers are just dodgy op amps. Would be most amusing to try and explain to your insurer as to why the throttle was stuck wide open when the crappy electronics in the bolt on TC fails lol. Variable vane inlets on modern turbos really help with any supposed lag anyway.

I test drove 15 yr old 4wd’s of the same model. The one’s without a throttle controller felt like there was a blob of soft dough under the accelerator. The tuning may have made the difference 🤷‍♂️

Tried one once on a modern Euro hatch with a small capacity turbo and a dual clutch auto transmission. Yeah I guess it sort of made it a bit snappier to drive, but as noted it sure didn’t cure turbo lag! What it did do was make it virtually impossible to drive in car park - the dual clutch auto boxes can be a little jerky at the best of times at parking speeds, but with a throttle controller it was horrible. Too much throttle off idle basically and the transmission ECU couldn’t deal with it - it was trying to let the clutch out expecting engine response to be less than what it was getting. No fun at all… I took it out and just learnt to step on the throttle more. Sorted :)

Hi I have a hykit throttle control in my prado 120 2003 with 1 kzte engine owned for 15 years put the throttle control in 2 years ago does not stop turbo lag but makes my car more reponsive in my case a much better response and like a different car to drive

Well dude, I have had turbo diesel engines since 2000. My current rig comprises a 5+ tonne, 6.6 litre V8 Duramax powered Chevy Silverado, hauling a 3500kg Bushtracker caravan. I'm here to tell you that I can DEFINITELY feel the difference since fitting my throttle controller. I'm not game to use it on the U9 setting. It's just too responsive. Instead, mine is usually set on AC which gives quicker response to pedal operation. When I am driving in situations where I need SLOWER response (such as climbing over rough, rocky ground) I alter the setting to a more conservative figure and I no longer find the vehicle jolting as I proceed. I agree 100% with you that what am experiencing is not a fix for turbo lag. It's simply a device that activates the fly-by-wire throttle in a different way. I was very sceptical when I bought it. But on my initial drive , a couple of years ago, I was IMMEDIATELY, able to feel the difference through the seat of my pants. Accelerating from 80 klicks to overtake a triple road train is now a much safer operation, despite my GCM being around 8.5t.

I bought one of these throttle controller after a series of messages from the seller, he assured me that it could improve the response of the fly-by-wire throttle body of my Kia Cerato, 2.0 NA engine, I was doubtful but it had a money back guarantee. I had it fitted to the car for 30 minutes, tried all it's modes and realised it was BS, contacted the seller and told him it was crap, sent it to him and got a refund.

Driving a Skoda vRS diesel the turbo spins up and starts working at about 2500 rpm. So to reduce throttle lag you simply have to change down and increase the revs before you want power for something like an overtake and then to the shock of passengers who normally drive petrol cars you have to change up before the red line which is only about 1500 rpm from when the turbo starts to do its stuff as once you hit the red line the computer says no and starts cutting the fuel so all the oily bits stay where they are supposed to live. Oh the wonders of a manual gearbox where you have full control :) And yeah at a traffic light grand prix you might pull ahead in the first few metres but once the turbo spins up.....

Accelerator pedal on modern vehicles operates a potentiometer which the program in the engine control module ECM uses to control the electronic throttle and thus the engine. So the cheat devices must have resistors in series or parallel to the accelerator potentiometer to 'fool' the ECM about the accelerator position. I reckon that's a $10 modification with parts from Jaycar. AND you stuff the OEM's throttle resistor mapping. Wonder what happens at full thottle - outside the throttle mapping.

@tungstentwohundredandtwent7007

Жыл бұрын

How do you “stuff the OEM’s throttle mapping”? With the the aftermarket throttle controller removed or disconnected the throttle system simply reverts exactly to OEM factory parameters. The controllers do not overwrite any factory parameters. As far as wide open throttle goes… zero difference. All the controller is doing is altering the curve of pedal input to throttle output. The end points, as in 0 throttle and 100% throttle don’t change.

I've got one of the EVC controllers in my 79 series, for me just makes the engine a tad more responsive or a tad lazier depending on what I want to do. Friend of mine also has an EVC on his cruiser 79 series, long story short he had his set-on auto and put his foot into it to get out of a sand trap on the beach, 79 took off like a "stabbed rat" (well quick for a 2.8 tonne brick), hit the edge of a dune and flipped onto it's side. He's just got it back after being off the road for about three moths having the body work repaired and the engine replaced. They can be quite dangerous when not used appropriately. Repair bill was around the $50k mark being conservative and not far short oof being written off I suspect. John, clearly what you say is true about the EVC units however, the "bees dick" of performance is quite a big bee, and might I add can be quite dangerous, on a couple of occasions when in the Ultimate mode and accelerating away from the lights I have come uncomfortably close to the vehicle in front. Hence, I drive in the E3 mode now which seems like quite a good compromise.

it's called "cone lag" that's the time it takes from when the individual first "pulls" on the bong and when there is significant negative pressure to begin drawing in the smoke generated from the "gear" in the "cone" and/or "funnel" for some individuals, and the smoke then to travel around the "glassware" to one's lungs and nourish one's brain with goodness.

Very informative again. I bet most people don't understand what's turbo lag. I didn't and I have had multiple people since decades ago, telling me effectively boost threshold (which they call turbo lag). some of them are even good at cars (eg. Capable rebuild car engine).

What he needs is a couple of Hiclones and Brocky's energy polerizer.

I just ordered one to dull the throttle down in my Mustang Ecoboost. For round town the throttle is way too sensitive, so I’ll see just how this goes

Does a throttle controller just effectively shorten the throw of the range between off and full ?

I'm not sure if this is the same or not , but can someone tell me what gains someone would have by having antilag. Besides a bunch of annoying backfires?

The delay isn't boost related.. There isn't any extra oxygen to burn more fuel so the ecu has to close the EGR valve and open the intake valve and 0.5- 1 second later fresh air enters the combustion chamber and extra diesel can be added then the turbo can start to spool up pushing more air into the combustion chamber. this is why you feel a dead spot then some resonance then full power 3 seconds after putting your foot down. and also why modern diesels with a manual transmission is so easy to stall at idle

Necro posting. You are both right, and wrong. Turbo lag and boost thresholds can't be fixed by a throttle controller. "Throttle lag" due to drive-by-wire can be fixed. The fix simply removes any delay or "ramping" that the ECU decides to incorporate. They proveably work. Should you get one? Jury is still out.

Its pretty simple ....dude. On the odd occasion when I need my Mu-X to jump off the line....spool up the turbo by pressing the ...right pedal, whilst holding the brake. Time this action seconds before the required break in traffic and ....viola,... your out of wherever you started from at the required rate of departure. Problem "Solvered" as we say here in SA. ....Thats Sth Australia, not Sth Africa

I have a throttle controller on my X3. Pretty neat, basically a gain knob on the throttle map.

I think the most relevant statement you made John was that these vehicles are 4wd's, not Ferrari's. If you want massive response and power buy a sports car, not a truck!

Best way to deal with turbo lag is always keep the revs as high as possible, never change up until redline. Also for best results a big sooty rolling coal tune will get more exhaust flowing earlier reducing spool up time. Yes I’m joking, if your a normal person and drive a turbo diesel for any length of time it becomes natural to add throttle input slightly BEFORE needing acceleration. Most modern cars are already so good at low lag and a wide power band compared to like 90’s era cars as well.

I have ford transit custom 2l ecoblue 2020 van, I can say it have almost no lag , used to have ford ranger xlt 2018 ute, the lag was terrible ,I sold it for that reason.

Contemplating my turbo lag while driving home to Far Kurnel.

Throttle controllers... just stomp your right foot harder and faster for the same effect. These controllers are the electronic equivalent of a smaller diameter throttle cable pulley on a carburetor. There, saved you a couple hundred!

Need a big snorkel and airbox to increase air density, air flow Furthermore a large exhaust to let the turbo spin. Look up Gale Banks diesel. A true, engineer.

when is any product manufacturer going to say this product is no good, they will always say their product will improve your vehicle, so never ask them "will this affect the manufactures warranty?", because they won't help you if they genuine won't

Beard Stocking Bear here I'd imagine that a throttle controller would assist in a low traction environment where you wanted to avoid wheel spin or wanted revs to spike immediately. This would affect the immediacy of Turbo Spool. Environmental Bias has been tested at length and the results are subjective so there's that. The Auto Expert Express has left the station Throttle Control on 4 (High), it left the tracks at midnight outside Piss Creek. . Waiting in hopeless anticipation on Train Station Platform.

In the future, would you consider doing a dedicated video on CVT transmissions on function and long-term reliability. Could you specifically address computer manipulation to create pseudogear shifting. I owned a vehicle with a CVT and had to deal with jerking and constant incorrect shifting. Thanks…

Our CVT does that, especially selecting incorrect ratios. Turns out the rear brakes hold slightly (after we were told by Nissan that the rear pads wearing 3x faster than the fronts is normal). The car does some calculations via throttle input vs speed etc, to select the ratio, but it doesn't account for the brake being on, and effectively bogs down and labours the engine. The car feels quite different when the brake is holding on (throttle response &, turn in especially). We've worked out how to release the brake hold by pushing the door brake hard down to it's stop 1 or more times. Once brakes are not holding, the CVT (and it's calculations) works great.

Me too. More so about whether the drive band is a weak point. Not knowing too much about them has me simplisitcaly comparing a belt drive to gears, thinking gears may be stronger?? Same question arose with old Honda Four (1970's) engines that had drive chains. Never worked that one out either.

Variable geometry turbos basically eliminate turbo lag for the average punter.

Damn you’re good. I learned a lot plus I’m now clean shaven!

Am I correct in saying that you can install a throttle controller for free by simply doing this - Everytime you accelerate - depress the throttle by 30% more 💀💀💀 ( I am now unalived)

I remember Mr Luxon from Safari who was amused by the term a "turbo lag". His point was that turbos make (more) power more quickly than naturally aspirated so what then do you call the lag in naturally aspirated engines? At 2k rpm most turbo engines will be making their max torque, whereas it might need 4k+ rpm in a naturally aspirated engine.

They don’t reduce throttle lag they just give better response the same way they do on a NA engine I have one on my V8 it makes difference I just don’t use launch because it takes off too quick but I do like the economy mode and the throttle lock mode

Alright geniuses, think of a throttle controller as another tool you can use, it does not increase performance, its brilliant in sand turned up, turned down for rock crawling, in the middle for average driving, all it does is shift the throttle position . I like it, as a tool, i know it doesn't add power . We're not talking a $1000 mod, its a $120 so no big deal.

Just fit an IHI roots-style supercharger, and throw the turbo away- between underbonnet heat, lag, reliability nightmares, and cost, a turbo simply isn't worth the bother. Fair call, you'll get sod-all boost above 5,000, or so, but when did you last see more than 5,000 rpm, on the road?

Hi John, The statements you say about your VPN sponsors (Nord/whatever), the Virtual location may not be illegal but most definitely is against the signed EUA with any streaming services. A quick google search will confirm this. My point is, your sponsors are making you encourage your viewers to break their signed terms-of-service with their streaming services. Fair enough if you're okay with it, but if not I thought you'd better know

Also John, modern engines that are bound by current epa parameters, will not overfuel which does help minimise "turbo lag" Complete fuel burn is only achieved through very accurate control by the computer not by said foot.

Mate I'm always impressed at the amount of energy you put in to describe a very simple concept to moron "beard strokers" as you call them. I would have been inclined to just say it's a signal modifier and that is all you fools and get on with thinking about boobies. Great vid!

Buying a throttle controller to increase power or performance is the wrong approach; it’s like buying a muffler for more power. However, their is real benefits to a throttle controller; it allows you to change the requested power at each throttle position, including reducing max power, so that the pedal responds in a way that better accommodates specific driving styles. For instance, a high-powered car used on track days can be reduced to max out at 50% power to make it much easier to drive on the road. Since going from 10% to 20% is a much bigger difference then from 80% to 90%, some people like to set a curve so the response is lower for the first half and greater for the last half so it feels like you get more power out of the higher throttle inputs. Others prefer minimal throttle input to reduce foot fatigue, so they set the curve to provide much more power in the first half and rarely use the last half of throttle. The throttle controller is a great tool, but it is not NOS.

Currently I Drive a Ranger (2015) manual - extracab- When I first got it, the Digital throttle response manipulation annoyed me - not endlessly as I am rational with these things, (it still does a little, but is it worth $200.) - doing a "Double shuffle" (yes not "needed" in a synchro box')- or merely a throttle blip downshifting from 6th to 5th - the engine response -is "very muted" (ie. nothing doing with less than a 2-3 second input - clutch depressed, or not, between 6th and 5th at near highway - exit - speeds....).. This is something a throttle controller module may indeed positively affect.
