Hey guys. So Im new to tuning, Ive been tuning for about 2 months. Ive read a lot on here, and help forums on the redline forums and cobaltss.net. I have 2 tuning books as well. I feel like Im doing a great job tuning, but idle cannot stay steady. Car is a 2006 Ion Redline. My mods are : K&N typhoon, ZZP s3 h/e, dual pass, zzp midlength header/catted downpipe, zzp 2.5 catback, AEM wideband, full bwoody mounts, gmpp clutch, 60's, 2.8", HP tuned, 2 step colder plugs, phenolic spacer, stainless brake lines, lnf shifter bracket, B&M short shifter, E85, LS4 TB. I bought a ZZP tune in the summer for my 60's on gas, and I used HPT to drop down to the 2.8, run on e85, and ls4 tb. I have logs to show what is going on. I have a AEM wideband, but I do not have the pro HPT so it is not logging, I usually just do short pulls and remember what the AFR is. Anyways, here are the problems:
As soon as I start the car, if engine is below 50* it isn't really a problem, but every other temp it is. Idle is nuts, goes anywhere from 400-2k rpm. I have tried everything, you can name it, I have done it. The idle hunt happened when I was stock, but not as bad at all, when I was on gas, on stock tb, etc. I even read knock at idle when the car adds timing to kick the idle back up! I have reduced timing everywhere, and I still get knock, im starting to think its false, perhaps because of my mounts. Anyways, idle does get normal after about 2 minutes of letting the thing do whatever. I don't let it do that though because, knock. When I turn off closed loop, reset trims, turn off short term, etc, the car can fix itself in about 30, but still reads knock.
Thanks for whoever responds! Appreciate it!
