Yes, it's in closed loop at idle.
Target AFR is 12.5 (or thereabouts). It's idling at 10.5. MAP values are yellow, target IAC is yellow, RPM is yellow. I have the throttle blade the whole way closed. If I change the values in the VE table to get the AFR at idle where I want it, it will stumble and stall as it tries to transition out of those cells.
I've widened the 02 correction parameters to the max it will allow (-25%) and it goes right to that max. AFR gets into the 11s when I do that.
For fun, if I tell it that I have 90# injectors the idle clears up very nicely, but obviously it won't run this way. As soon as I move off of idle it stalls.
It worked when I first installed it, I'm not sure what I did to it.
I'm out of town the next few days and won't be able to goof around with it until Thursday or Friday.
Why don't I want it idling in closed loop?
I appreciate your offer, but I won't be home until later this week. I do have a couple of log files I can send you an Blazer406.
Thanks,
Jim
