Tuning a 2008 Z06 with a built engine and twin turbo setup. On the dyno everything works flawlessly. On the street, It has spiked the IDC just for a split second which does indeed over fuel the engine badly. The car almost coughs on the excessive fuel but before I even have time to let off the IDC goes back to normal and the car continues to pull.
This has happened twice. Commanded AFR doesn't change, and the VVE table doesn't have any weird value or spike where it happens. Could this be a bad computer or a grounding issue or something?
I'll post a log and the tune file in a bit.....just wanted to see if anyone else has seen this. This is the second car that I've seen have weird and random injector spikes during wot. The other car that is doing it is just an 0411 pcm in a swap application.
