OL-Fault?
Well just as I get my tune finished (for now) and get the WOT PEs rght on my PCM seems to be locked in OL. It starts in OL, warms up, and goes to OL-fault as reprted by Scan. Never records LTFTs cause it never gets there. What have I done ?
Thanks for any help.

Is your MAF fail freq set low?
Is your MAF plugged in?
Email me your tune and I'll take a peek.

Who needs a MAP sensor on a supercharged LS6 anyway.
Rick,
The MAF is and has been hooked up . It reads .9 at idle and seems normal. I have not been trying to run MAFless. When I disconnect the MAF the engine definately notices. No codes, but running 19 to LEAN @idle on PLX. Old tunes where it def. went into CL do not wake it up.
I will send you the tune.
Many thanks,
Bruce
Still no go after a few hours of trying various stuff.
Update> looks like a bad 02.
Update 2> replaced 02s and life is good again.
Thanks :lol:
