I'm really confused....
 

For the last couple of weeks we have been working on the idle on my 99 Corvette which doesn't get driven as much as it should. I've gone up and down with every table and basically chasing my tail. Today I went to the extreme's and am really confused. I 0'd out the IAP and Effective area and the car idles and runs exactly the same. Whats up with that???

have you gone back and fooled around with some timing. Have you done an Idle Relearn on the Vette. How much time have you given the car to learn the new settings.

I increased my raf table to values that shouldve resulted in hanging idle. it took a week before i actually seen any change in idle characteristics. Car gets driven about once every week- week and a half
