Tuned 00 Corvette 233/239 Auto SS3800 Combo I just got finished tuning a friends 00 Coupe. He has an Automatic with a SS3800, stock heads, 233/239, full exhaust, ported TB ect.
Started and logged warmup
Averaged data for 20c,40c,60c,80c, coolant temp vs MAF gm/s
Input that data into the Running Airflow Table
Idle Tuning:
400 and 800 VE reduced by 75 / 80%
IAC Park Reset 320 -> 160 -> 120 -> 105
Input that logged data into the Running Airflow Table
Bumped timing 2-3 degrees low end
Idle RPM ~900
We started the car up and the idle stuck @ 900, cracks of the throttle end in very little hunting(100rpm). The LTFT are alittle high 10 - 15% crusing and the car seems rich on the top end. We're going to weld another bung and use my WB to log the A/F. Any thoughts on reducing the LTFT cruising?
