Rich at idle
Ok still going round and round with this crap with the tuner. He says nothing he dose will control how rich the car will idle at, so my question is WHAT in open AND closed loop would cause an LT1 to idle rich? lol Specs are in sig
Oh yea and it's fouling out plugs every 500 to 1000 miles and O2's at about 2000 mile intervals.

yes I am somewhat sure as the idle changes and the IAC will back off and not be screaming at me through the CIA. But once the plugs start to foul the idle stays high and the IAC is always screaming through the CIA.
It has a BBK 52mm on it. Ran it with the stock engine in there before the build and never had issues with it.

I guess I just need to pony up and buy a damn wide band to look at it. I just found it odd that he said he couldn't control anything at idel in the tune? Is that correct or is that BS? It is an OBD II PCM but I have a OBD I that I may have someone tune but I guess it really wont matter.

On my scaner it says LTFT+3 one bank and +10 on the other. I did a data log this morning. Timing is holding at around 34deg cruising at 45 under light throtle(10%TPS).I can do an idel data log if needed. I don't know much about what all the numbers mean in the data log. So +12 above 128? makes no sense to me. I am tring to learn what it all means so any help would be great.
