When it's reading that lean per the cobb / accesstuner race even flooring it and theoretically forcing it into open loop does nothing for the AFR reading.

I'll get the UEGO installed asap. I see the aftermarket downpipe seems to have a plug & a spot to screw it in, so as long as it's not welded in place (looks like someone partially butchered this downpipe in it's past life) I'll be able to see what's *really* going on.

It's really baffling to me, too. I knew the cruise went on w/ the CEL, but never knew it could go on by itself. I've managed to workout all the issues that were causing misfires and haven't registered a misfire since.

I actually have a bunch of datalogs posted over on the cobb forums if any of you guys are curious to see the raw data for yourselves ... the thread is: https://forums.cobbtuning.com/forums...421#post669421

You can clearly see it happening -- it's massively weird and totally disturbing at this point ... I mean, WTF!
