Brock Davidson Hey Brock. When you receive the new recalled ECM did you just download your same Flash with the power commander of the previous ECM that you already made or did you create a new Flash and map for the new Ecm. Also can you explain more about the studded in gears 2 and 3 because I never felt it on my bike when riding. Did it show up everytime you did a all gears run?

Great video, thanks for the time and effort in producing and uploading it. I've been wondering whether to go ecu flash or PC5 on my 750. seeing this, I think I've decided PC5 for my requirements will be just fine. Yes, maybe a touch more outright power from a dedicated ecu flash but its going to be negligible gains over a Pc5, that will also be custom mapped for my bike anyway. Great video.

Very interesting Video .. I installed a Boon docker fuel controller and an Oxygen gauge on my Yamaha snowmobile because it ran way to rich stock .. My Boon docker does not control timing but a 4 degree offset keyway really improved my MPG and HP by just a little .. It's an R-1 engine that turns 10.500 RPM .. It's great to know how close stock timing is to perfect . I have never worked with electronic fuel injection so of course I wondered how accurate and close the controls are how precise the injectors are ect.. there must be a lot of variables in flow .. I deal would be 4 oxygen seniors 4 spark knock sensors and active tune controls for each cylinder.. Seems an onboard Oxygen gauge would be handy .. Looks like your videos make a great sales pitch for the active tune system... For a street bike it seems like you can have the best of both worlds great wide open full power yet could cruising mpg .. Your first gain of you explained is to get away from being too lean as stock bikes are..

Thanks Brock. You proved my tuner knows his shit. When I took my K7 Gixxer 750 in he told me to keep my PC3 to tune with the flash he did. He gave me the graph showing the bike when it arrived, after the flash and after the flash and PC3 map. Hell, he even emailed the PC3 map in case my PC3 ever fails.

It really is a masterclass. It almost feels like you are telling too much from the kitchen. But really Brock- props to you! What a stud

Yeah this is an old video but I've just bought a woolich programmer/logger and am in the process of tuning my own bike. I'm technically minded and the systems are pretty straightforward if you're patient and dont' change things without understanding the impact. I like that you're honest about the power commander vs flash situation. I also like that you're honest about the time it takes to develop a good flash map but that it's also worth it in the long run. Luckily for me with woolich specifically I can just ride around with the logger plugged into the bike and then load it into the software and adjust based on the logged AFR readings. Once people start to realise that these systems are as easy as a DIY oil/filter change and less complicated than throttle body syncing we might find more people prepared to go down the DIY route. Especially those that do their own servicing.

Hi Brock, I’ve been following your stock to brock series very closely. I’m currently working on a 2017 GSXR1000R with Bazzaz ZFi & FTecu flash. I’ve taken a look at the throttle plate mods which is already in place for the ECU number I’m using so I’d be expecting not much power gain from a base run I did on the dyno. As mentioned earlier, the bike is running on Bazzaz ZFi, FTecu flash (EU flash), sprint air filter, decat with SC project end can. Do you know as to why I am not able to achieve a power gain despite the above? Stock: 168-170hp

Awesome video as always- My Bike is "stupid fast" already otherwise i would definatley be a customer.

what euro4/emissions things (particule filter, sensors, software etc) did you end up deleting and changing? The s1000rr for example gains top end when blocking the nox sensor and relocating the air temperature sensor to further out the airbox. what kind of things do you think thr gsxr would benefit from?

Is it true the 2017 Aprilia isn't tuneable only with the PCV because the ecu corrects what you have done?

We can tune it to be much better than stock using the PCV, but It needs to be flashed also to try to keep the throttle blades open 100%. I say try because BMW's Bosch ECU's don't work like the Suzuki's Denso unit - you can't just jump in and tell them what to do.

Thanks Brock! Epic series. Loved all of them. Question about humidity, if your dyno room was air conditioned could you get consistent results within a small percentage? I had my bike dynoed on a humid wet day and I cant say its perfect, would the humidity have been a factor?

@BrockDavidson

The amount of energy needed to truly heat or cool a dyno with a smoking hot bike running inside is tremendous. We built our room inside a 12K square foot warehouse and use the temperature of the floor and concrete floor and surrounding components to help cool the inlet temps a bit. That said, in the heat of summer, that room might as well be located in the parking lot. We have seen 108 degree ambient room temps in the summer. The sensors on your bike allow a wet/humid summer map to work well year round. We do have hot weather maps for some bikes.

Hey Brock, just came across this video and first have to say awesome job very much enjoy your videos and all the knowledge you put out there thank you sir. I do I have a question though you said there isn’t a problem with ecu fuel tuning but just with this bike specific. Have you seen or know if there is an advantage to running a power commander in combination with guhls flash on a 14r? I will be purchasing the AH2 full system in the next few days and was just going to send my ecu back to don to have the fuel corrected for the new exhaust, now I am wondering if I should have the fueling flashed back to stock and get a PCV lol thanks in advance.

HI Brock The FI on all Honda CBR from 2008 when started commence moving the timing forward in large increments automatically and will continue to advance untill the knock sensor detects knocking, when knocking is detected the ecu retards the timing by the last increment and then rechecks, if a knock is not detected then the timing will advance in smaller increments unit again a knock is detected. This continues untill the max timing advance is achieved and no knock is detected. This process occures each time the bike is started. It is designed to get the best advance setting regardless of fuel used, considering this, is possible to flash a different timing map on a CBR 1000rr or flashing a Honda only involves the fueling?

Hey brock, you use power commander alot in your vidoes. I was curious to know what is your take on bazzaz vs power commander? Just curious to know why you wouldn't use it considering it controls more injectors. Thanks for the informal video and keep them coming!

@BrockDavidson

3 жыл бұрын

We choose the PCV because it is designed to work hand in hand with our model 250 Dynojet dynamometer to create the fastest/most precise/smoothest maps we know how to make. I have never seen the need to tune the secondary injectors in stock engine applications, even when using highly oxygenated fuels. The Bazzaz unit works well for use with modified engines and general self-tuning when matched with their Z FI module. Unfortunately, low throttle openings are not tunable, which can be a hindrance to smooth operation on some bikes.

Hi Brock, I own a 2015 ktm superduke. I left the stock headers but I replaced the catalyser with a link pipe and I have the Akrapovic slip on , I saved around 10 pounds ( 7 pounds from the catalyser and 3 from the slip on ) I didn’t replace the headers because It was way cheaper to take off the cat then to buy the 2 grand full line. I also removed the stock air box and installed the Rottweiler air box ( way more air comes in ) I installed a power commander 5 and an ignition module and had it tuned on the Dyno. I do feel that the bike is more powerful but I find that when the weather is hot and humid the bike doesn’t perform as well ( not even close ) to when the weather is cooler. Do you think that installing an Auto Tune would fix that problem? Another Question: do you think that the setup of my exhaust without the full Akrapovic header was a good idea? I mean do you think that the Akrapovic headers would have increased the performance? Cause in my point of view it basically ends up being equally the same. Thanks

@BrockDavidson

5 жыл бұрын

petelpete - headpipes are the part of the exhaust that improve horsepower - a slip-on improves the look and sound. As far as hot/humid weather - some bikes compensate for it better than others. You can create your own -5% across the board 'hot weather' map and select between it and the map you are using by installing a map selector switch: brocksperformance.com/dynojet-map-selection-switch-power-commander-v/ if you had your bike tuned by a competent tuner, you should not need an autotune unit.

Hi Brock... i've been watching from the begining and starting on the 190hp, passing by the 204 and now 190 again it sounds kinda strange... however, it's not all about HP... i noticed you never mentioned anything about torque, it is because you don't find it relevant for your tune or because you simply decided to ignore it...?

@BrockDavidson

6 жыл бұрын

@MrGuerra - we have mentioned torque as the force that accelerates the vehicle from the beginning of the series. That said, we find that it's not easy for the average person to relate to this increase. In episode 2, we made 165.73 RWHP SAE- in E7P2, we are now at 194.14 RWHP SAE (an increase of 17.5%). It's fairly easy for most to understand that we now have a MUCH faster motorcycle. If I told you that we gained 6.19 ft-lbs of torque (a 7.5% increase) over that same period - would you understand this to mean the EXACT SAME performance gain? We will get into torque multiplication, and it's benefits (or downfalls) in more detail once we get to the drag strip.

So brock I'm confused when you talk about the exhaust on the bmw and the gsxr you said you went with the alien head cuase your going drag racing but if you wanted more midrange torque you would go for the predator. I thought midrange is exactly what you want to be better for drag racing doesn't the midrange help with acceleration?

@Jock - Great question. In drag racing and land speed, the bike spends almost all of its time in the high revs and WOT. We can make simple gearing adjustments if we want more torque or more speed. Dropping 1 tooth on the countershaft has more of an effect on acceleration than we could ever build into an exhaust. In road racing, the bike spends most of it's time with the throttle partially open, especially on short courses - this is where a broader power/torque range is most benefitial.

Can you explain why @5:50 we see the map numbers jump from 16 to -5 within 250RPM? I would expect to see much less variance between numbers and see a smoother transition. Fantastic series btw love your work. I have a 2010 gsxr 750 with straight pipes (no cat), M4 and a power commander 5. I bought it with a dyno tune on it with a custom map but I am not sure if it had a custom ECM tune as well (have the printout though). - just looks odd when I see the trim numbers change so drastically.

Also, can you explain how the gsxr's have a power mode switch (A/B/C setting) affects the maps/AF ratios? - I am unclear what the power mode switch actually does. (retard timing?, change AF maps?) My spider sense tells me that if you muck with the modes it is going to affect the air fuel burn which is going to throw the map out because the map is tuned for a specific config.

Large jumps in small rpm's are required to keep the AFR correct throughout the range. This is common when a precise AFR measurement, under load, is observed. This doesn't happen in the stock ecu mapping... Which is why stock ecu mapping works so poorly. If you add a wideband sensor to your pipe and go for a ride, you will see the same results, once corrected.

@@BrockDavidson Thanks Brock! I have rebuilt many car engines from full tear downs but the whole Air fuel thing was a complete mystery to me. After seeing the first video I binged the whole series like I was watching breaking bad for the first time. I am hooked. absolutely fantastic. You are a master in your craft!

Hey Brock, as much as I want the gixzilla to be better than the bmw. Didn’t that bmw still have restricted throttle blades? If so wouldn’t it most likely be making more power once de-restricted?
