I bought a 95 Camaro to tinker on, im very versed in hptuners with gen 3/4/5 ls and lt engines but first time ive ever messed with one this old.
Car has a 355, GM847 Cam, Jegs XHD Converter, Longtubes and 36lb bosch GTP injectors. It seems to run pretty good will go 12.0@112 on the street havent taken to the track yet only dragy times but i have a few questions on the tuning side on these.
There seems to be a timing adder in there that will pop in another 1-3 degrees at times over commanded. I cant find a afr spark advance table like the newer pcms in it, what could it be coming from?
TCC PWM, i do not lock the converter wot but i can tell it needs the pwm disabled if even possible in a 95 4l60, it kind of slides into lock up
I cant seem to find any good injector data for my bin file with the 36lb injectors, for now i have just changed the flow rate and went from that but would love to have the injector offsets correct.
Car is around 12.5-6 afr wot i plan to lean it up and see if it picks up after i get a cold air intake on
If theres anything anyone sees let me know, this is my first swing at tuning one of these dinosaurs
