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

You'll need to log commanded AFR, and make sure the two tables are set to different values. As stated above, the PCM picks from the richer of the two. When mine goes into PE mode, the commanded changes from ~14.7 to ~12.8 on the computer screen.

I've never heard of one that will tell you which
one is the source, but the Fuel Air Multiplier is
the result of all the juggling and by also logging
RPM, MAP and ECT you can tell which one it was,
by which one's axes point to the FAM value seen.
Unless you have the adders / multipliers chiming
in, then it gets to be messy.

Ok, I was sure I heard someone said there was one.
So if the numbers in the OLFA table is numerical higher than the PE table. I will only be using the OLFA?

Then I am confused. My AFR is still in the 10's. So I scaled down my PE. That help a bit. But then it wouldn't lean out anymore. Ok, lets start scaling down the olfa. Nope, I can't get the AFR out of the 10's.
What else would be keeping it that rich?

SAE.FUELSYS
This will show you what the PCM is commanding. There is a nice explanation in EFILive 7 Scan.

Ed, is the problem you can't get the actual afr to go leaner or you can't get the commanded afr to go leaner then 10's? If you want you can send the file this way and maybe I can take a look at it. Two sets of eyes are better then one on some things.

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