Anyone have ideas for tuning this beast? spent most of my time on gen 3 trucks. Throttle pedal feels dead compared to my 2011 sierra 6.2l

lots of info in this section of the forum. have you read it and now have a specific question?
Looks like I have some miles to drive logging the dd and adjust a little at a time.

From what Ive been reading, most are saying I should adjust only the 100% throttle area of DD tables? Is there a reason the yukons and pickups have values above 12000 in the 0 column and falling as the speed increases, yet a stock corvette is only 364 all the way across?

2014 is engine torque in kilowatts and 2015+ is axle torque (might be in newton meters or torque, not sure)Originally Posted by ontarioss
Pretty much so just think about how it works and make small steps.Looks like I have some miles to drive logging the dd and adjust a little at a time.
Because its axle tq it looks at gear ratio to figure out the throttle openings
first gear 4.5596 though rear end gear that a lot of axle tq,
Just making shift speed changes messes up every thing(can change axle tq readings)
you need to log app tps vs other tps pids to see whats going on this system is very complex with axle tq
things can get out of wack.
Making changes that can get multiply many times and ways is a little scary kind of like hoping you put your throttle spring on right
but know way to test it
ontarioss, hey I was wondering. I put your tune on my 2015 Yukon Denali and it was jumping and revving high as soon as I would put it in drive or reverse. Any idea how I can make it stop doing this? Thanks
If you put your old tune in your editor along with the tune you just loaded into your truck as a compare file you should be able to see the differences you just loaded in and can then change them to something that will work for you. In general you shouldn’t load a tune onto your truck but instead make changes to your original tune in a controlled fashion because there could be something different that you might miss that does not work well with your engine. Besides loading a stock file that matches your hardware as a starting point or loading in a tune file that was specifically modified for your situation by a fellow tuner you could blow up your engine if not careful. Just putting this out there, not trying to be condescending, hopefully this is something you know already.
