Much appreciated. This stuff doesn’t need filler in my opinion, it’s a lot of information to convey, and listening to me ramble on too long can cause adverse side affects, at least if you ask my wife lol. I’m happy I was able to make it understandable for folks like yourself that may be new to this very complex animal we call tuning.

I've watched dozens of videos on this topic and this is by far the best ! I think I'm finally starting to understand this. I grew up in the muscle car era with points distributors and carbs , so this has been a struggle for an old fart in his seventies . Thanks for taking the time to put this together

The best tutorial I have seen, thank you!!!!

I appreciate your feedback. When I’m done with my other projects around the house I’ll try to make more videos. Probably around 2050 or so lmao. J/K I’m on another overseas tour in coming soon so I’ll actually have time to work on these again. Maybe around next year I’ll have some more good content. I definitely want to share some Gen IV and V knowledge with all of you. I don’t make a living tuning so I don’t mind sharing the trade secrets. Seriously, most dyno shops are fucking hacks anyway. That’s why tuners literally live by reputation and not quantity of cars tuned. I don’t care if I tune 1 car a year, what I care about is taking my damn time to learn that particular car and make it drive perfectly. I have a badass reputation in my area as a result. Because I’m not a pro. Funny how that works lol.

Thanks for the help, this great .

Hey man i love your videos on tuning and have been able to get my truck driving pretty well. Except my PE/BE has been causing me to go pig rich at 9-10afrs at 2000-2800 rpm after that it pulls back up to 11.5 and holds pretty steady. Any recommendations?

Great video! You using hp tuners pro? Wondering what kit will work because I think not all kits have 2bar rtt for ls available.

Hey, I really appreciate all of your informative videos. I have a question. Im trying to change my OS to 3 bar os as I just bought a 3 bar map sensor (although I plan on running 14lbs or less atm) but when I open the OS tab I only have options for SD enhanced, 2 bar, and 1 bar maf. Is it possible to change my OS to 3 bar or run my three bar map sensor in 2 bar OS?

Haven’t done much with Dodge, but I’ll keep it in mind for sure.

So I got my VE dialed in without the boost--car ran great. I added back everything I had disabled except for the MAF and created new tune with 2 bar OS. Followed the directions on this video on setting up expanded VE table, spark, PE and Boost Enhancement as you suggested. Did the "Write Entire" as instructed. When I attempted to start the car, it didn't want to start. I finally got it running by holding the throttle open a little but it ran very poorly as if it was extremely rich (smoking also). Put it back to the previous tune (Write Entire again) and it cranked up and ran fine. Went back and looked at the VE table in the 2 bar tune and the lower half was exactly as the original tune. What am I missing? I see the cranking VE tables but they are identical in both the original and 2 bar tune. Thanks

Nope. MAF is essentially disabled with a SD OS.

Reading it and seeing it done really helps with learning how to do these things. I was wondering if you could possibly do one with fuel adders like meth injection or adding nitrous to a boosted application.

Perhaps, but in reality, it's not difficult in concept or much different than this here. Just make sure you pull more spark out, and keep the AFR where it needs to be and life is good.

@@ChopperDoc181 I have read of a few ways to do it like for meth inj for example. Making the tune lean spraying to get the afr wanted, spraying on top of the tune to just be rich or the part messing with the IAT spark when it is active so if or when it doesn't spray the tune stays safe. I haven't seen a video talking about this and you do a great job explaining all these things.

@@supernova5end For a nos tune, some guys do the IAT chop switch, which all it is is throwing the IAT to ground so it registers the lowest setting. Then adjusting to the amount of spark wanted. Some guys do this to the MAP sensor too. As in throwing 5 extra volts at it to "double" the reading, which allows use of a 2 bar tune, where the 2nd bar is the nos fuel map. Most though simply use the nos controller as most will pull spark for you. There's a lot of ways to do it. I may do a video at some point. I have my IAT wire ran into the car already ready to be spliced in later down the road. I was going to put it on a toggle switch though, so I can activate "fireball mode" by retarding the timing on decel... Just for fun. Lol.

Gen 3 3 bar. Could you do a video on how you go about scaling airflow so you get to use more of the timing table. I understand the principle i think. But after its done how do you tune ve if its scaled. Or does that part not change?

@ChopperDoc181

4 жыл бұрын

I’m actually working on this currently. Everything will change, but technically it should remain pretty much the same after the scale is applied. You should still confirm obviously to make sure everything is still spot on. I’ve scaled mine before, and I had a few small issues but nothing major. I ended up going back to the normal data though because scaling by 20% is a lot harder than 50%, which I was using at that time. it was way too much lol. In fact yesterday, I made an excel calculator for the upcoming video that helps you shift the spark tables. I will post that on tech pretty soon, hopefully when I finish the video which is taking a minute. it’s a lengthy complicated procedure to put into a tutorial form.

Yes. When you get boost enabled, note the RPM where you start making boost as well and ensure it’s 11.5 there and higher. Use the boost enrich as a backup. You can leave it at 12.5 in all NA RPMs (under 105 KPA).

Is this a similar to turbo tuning?

You mentioned at the end to put the IAT into the intake manifold. Did you mean the cold air intake? I have an 04 GTO Gen III with a TVS1900 that has the IAT installed in the blower itself. I’m sure there’s a reason why, but I don’t know it. I have been considering moving the IAT to the cold air intake due to the fact that temps get pretty high at idle and part throttle cruise speeds.

@ChopperDoc181

2 жыл бұрын

No, the it’s better to put the sensor in the manifold and then disable the IAT bias. Otherwise you will have to tune the bias vs ECT table. This is only further complicated by boost. If you go to your “cylinder charge temperature bias” hover over it and read the description at the bottom. It’s recommended right from HP Tuners. The high temps you are seeing are the truth of what is going into the cylinder, provided that the sensor is as close as possible to the ports (ie the intake manifold). It’s better to know the truth then mask it by putting it on the cold side just for the sake of lower numbers. Having said all of that, it’s also a good idea to visit your IAT spark tables and adjust accordingly since it will adjust to a “new normal” range. You shouldn’t have to do much but make sure it isn’t adding in too much spark under load. Hope that helps.

Makes sense and that’s what I have been doing. I’m am running a 2 bar SD OS with a MAF that the meth controller uses to activate. My spark tables are in pretty good shape (really close to your examples. 27 max on mine). The info I have found about the IAT placement makes sense too and agree with your assessment. I originally had an MP112 that had the IAT in the intake above #8 cylinder that was heat soaking, not reading the actual IAT. It would climb to nearly 190 degrees with 60 degree ambient temperatures at idle! It was miserable to try tuning! Going to the TVS with the IAT near the intercooler dropped temps to a high of 125-130 and the meth injection drops them a little from that, but I want to get away from meth because it really doesn’t help with a PD blower setup and it eats up the rotors to boot. I have been concentrating on cold start stalling that has been hard to work through. It’s also way too rich overall, but I’ll have to wait until next spring when I can log in warmer weather.

@ChopperDoc181

Yeah it may be a little trickier with a PD blower, but it’s still advised to keep it there in the manifold/blower. Boost does create heat, so it stands to reason some of it is real and not just heat soak. Mine is towards the front to avoid some of the heat coming off the exhaust, and to gain some cooling from airflow from the front. Mine has seen as high as 160* on summer days, but in my case it’s real, due to the shit design of the 4th Gen Camaro radiator and intake system. I have plans to fix it with a better stand up radiator, and piping over top and to the nose area so there is less exposure to the heat from the radiator. I’m going to insulate it too. For now I’m just stuck with high IAT’s at idle. But with the bias disabled, the AFR doesn’t creep much even when it’s that hot. It sounds like you have a fun setup. I’m really glad to be helpful to folks out there like yourself. For those cold starts, make sure you have enough IAC (if applicable) and/or port it out a bit. After I did that on my FAST 102, it colds starts A LOT better. Also that’s with a massive N/A cam that idles at 75 kpa. That definitely doesn’t help. I also play with the spark using ECT correction tables and add in more air the cold start areas. It may help to play with the O/L AFR correction too. Depending on cam, most don’t like a ton of fuel. It may be flooding out the chamber and having a tough time lighting it due to the lower airflow from aftermarket cams.

I have a Kenne Bell 102mm without IAC that I’ve adjusted numerous times from closed to open about 20% according to the TPS (I reset the TPS to 0 each time) and drilled from 1/8th to 1/4” in steps to no avail. So I have refilled the hole and it is currently open to 20% where it seems to like it the best and still idle at 850rpm. No matter how it is adjusted, I have to crack the throttle open an additional 20% on initial crank up cold which is around 1600rpms and hold it for 15-20 seconds before letting off, then it idles fine. Anytime after the initial start that I start it, I don’t have to touch the throttle. My current tune was done by email which is the initial one. Now he seems to of disappeared. Won’t answer his phone, emails or texts though his website is still up. He also locked the OS, but that hasn’t been a problem so far. So now I’m relearning HPTUNERS so I can clean up the tune. It’s far too rich throughout the VE table. That I’ll work on next spring when I can drive it again in warmer weather. I don’t think logging in 35 degree ambient air will help in correcting my VE table. Maybe I’m wrong. I understand your cold air intake problem. I’m going to use the Vararam when I can get one. They tell me they’re months behind getting them out due to not having filters. That system solves the under hood hot air problem by getting air from ahead of the radiator. Worked great on my 06 GTO! I do appreciate your expertise! This is a stock body and interior car with the spare and jack still in it. I just converted to a 4L80E after destroying 8 4L60’s and I finally got it dialed in just as winter set in. I’ve run its best ET at 10.69@124mph with this tune and think it will go into the low 10’s cleaned up. Now I have months to relearn how to fine tune it.
