Ok i have a 96 LT1 t56 that i did a 411 pcm swap on, wiring is very easy but im very new to programming. ive got the car running and driving but i feel like it is just a little sluggish. for the most part i used a 5.7 express tune but it seemed to idle better if i just copied the 2002 camaro idle section.
i ended up just backing the entire spark table down on high and low octane to make sure i didnt have spark knock when trying to get fuel trim in. i ran pretty ok like that and when i raised the timing back up it ran better except at higher rpm where it was spark knocking. so i backed it back down and thats kinda where i am now. do i need to just start over from square one or at least build a spark map from scratch?
the car is completely stock. i have a wideband but i dont have anywhere to install it because of the cats so longtubes are next on my list of parts to buy.
