I think im looking for a 482 in particular, but nnot sure if the 501 would make a difference...
Chipping my ecu:
Base idle set at 850rpms
3G MAS conversion w/extended maps
Stock sized 450 injectors
AC cutout at 80% throttle
Revised and extended closed loop maps for better highway speed mileage
Remove fuel cut
Rev limit is stock at 7200
Check Engine shift light at 6800
Dash LEDs converted for knock sum counter (each light is 5 counts)
Waiting on feedback from my chip maker but maybe you have some insight on this?
