Thanks for the feedback and comments. I've read and re-read the PCIII installation manual and intructions. It's not that the PC disables Adaptation it's more that without a valid O2 signal, it can't adapt.

Looking at it from the PC viewpoint it doesn't want the Motronic to adapt because the PC wants to be able to add fuel without being countermanded by the Motronic's adaptation.

I'm told the widebands are fast enough to look at individual exhaust pulses but am sure that neither the PC or Motronic are set up for this nor are they fast enough.

My experience with this is that 4-6% more fuel, open and closed loop make a great-running 1150. Either PCIII or LC-1 can do the job but they have different pluses and minuses.
