To continue the discussion...Sorry Gale for stealing your build thread but since we all happen to be having similar issues and would love a solution, figure you won't mind much. I thought about this more last night and watched it pretty closely the entire way into the office this morning.
- My AFR idle is no where close to as bad as the one in Cell's video. I bounce around from 14.6-15.2 but not as erratically as that. I'm also convinced my Innovate is a couple tenths high on readout. It's always read that way and everything checked out on the dyno as good, so I just live with it. All My idle rpms seem to be pretty close to inline with his.
- One thing to note on my tune. The problem in question was much worse on the base map from Vince. I even sent some log files thru Sasha to him, received an updated base map and it didn't make it any better. I mentioned it to my tuner when I got my custom tune. I don't know what else he might have done behind the scenes but I know for a fact that one of the things he did to compensate was adjust off throttle idle timing. If I remember correctly when coming off throttle and dropping rpms, he added additional timing starting about 1200 rpms until my idle set point at 850. He told me he did that to specifically fight the hiccup we are all experiencing. It didn't fix it but it's way better than the original base map.
- To throw another monkey wrench in the discussion. I performed the throttle body relearn procedure a few weeks back. The first couple of times I ran the car after that it almost completely fixed the issue. Within a day or two it was back.
All in all no real solution from me but figured I throw the items above out as additional data points. I would love nothing more than to get this figured out because it really pisses me off to have a car that I worked this hard on and spent this much money on and it just doesn't idle right. Makes power all day, runs great in open loop but has random hiccups under no throttle.
