I just got my JWT ECU back from adding the S3 program. I've only driven to dinner and back (~5 miles round trip). When I push the clutch in, the idle drops to 500rpm, bounches back to around 1000rpm, drops back to ~700rpm, then settles at 1100rpm. I have the base idle set at 800rpm, and timing is at 15 deg. Any thoughts? The stock ECU did not do this. Maybe I haven't given the ECU enough driving time to learn the car. This is in my '96 SE-R.

I talked to Ray Kawski today ( there might be another problem 
) and he said to put the TPS voltage at .45v. I checked mine, and it was at .387v. I adjusted it to .454v, which was the closest I could get it. At WOT, all I get is 3.98v. Mike, do you think this could cause the power issues we talked about earlier? I let the car warm up, and reset the TPS memory like the FSM says to, and the idle is still at 1200rpm. I didn't drive it after doing this. I did noticed driving home from work, that the idle doesn't dive bomb anymore.
