PE & OLFA (pid)

[Ed Blown Vert]

What is the name of the pid that tells you which table it is using when in open loop?

[Dirk Diggler]

there is not pid you can tell the car is in open loop when you see FTC 22. when you see this the car is pulling from the OLFA table and if the computer needs pe it will pick the richer of the two values

Thanks, but that won't tell me which table its looking at.

My issue that I am trying to fix is I cannot get the AFR any leaner than 10.xx in open loop.

Was hoping there was a pid that would help.

I assume that is commanded AFR, not actual?.

Its actual, I have a wideband installed.

I can't get the actual afr to go leaner. I have a wideband on the car. The problem may be I tune the old fashion way when LS1edit was the only thing out there. So I scale the IFR to get my LTFT's negative.

So far everything is working well, except for this last item.

This is a quote from a thread on Tech.

IFR out of whack, VE out of whack, MAF out of whack, PE out of whack... AFR out of whack.

Hmm....thats alot of help

Sorry, my comment was pretty lacking... I don't know what heppened...
I meant to say to use the Speadsheet to recalculate the IFR table and then try an Auto VE tune (and recal the MAF table from this, or just run SD) and see what happens, but you've probably already been thru all that.

Cheers

P.S. Nice car.
