Hello,
as some of you may be familiar with, I had an issue with my corvette and some knock retard a few weeks ago that i tracked down to injectors, cyls 1 and 3. I am wanting to make a bit more power and go over to e85, so i bought a set of bosch green tops, and plugged injector data into my tune. Now, during a cold start (still on 91), the car will run for a second or 2 and then die. I can't give it any throttle to keep it idling, it just chokes and dies. This problem stays until the car warms up and then idles well. I don't have a cold start log of the car, but I have a log of it running when warm, and the tune file. Prior to the injector install the idle was good, never had problems starting.
So far, I've been scaling down the injector offset vs volts vs vac table in order to lean idle out to 14.7 afr, but that hasn't helped this cold start issue.
I'm sure I'm missing something and would appreciate a more experienced tuner to point me in the right direction.
