Do some additional reading. Open loop means fuel trims are disabled.. can't tune with something that is disabled.
You can use fuel trims to tune part throttle areas. A wideband is needed for WOT tuning.

After confirming that everything is working properly, what is a good recommended cell hit count to use? I upped mine to 20 from the initial 5. Any thoughts on that?
is there something to trend/watch in the scanner to know if PE is enabled? Or is it best to just go up the settings in the editor before scanning?
20-50 counts is good to aim for, the more the better IMO. A normal 15-25min scan log should net you plenty of information to help you.
Lew, you can log the PE enable/disable status in the main channels list to see if it's active or not. You can raise the enable settings in the editor too if you wanted, like something around the factory 85-90% tps like most GM vehicles are now.
Thanks for the info. I left it at 20 counts and did a 30 min scan log yesterday. I haven't applied the changes and reflashed yet but I got good info from the log.Quote:

Where does a person find a list of those numbers and what they go to?Quote:

There are other ways but that's one

Post was deleted but basically the numbers on the right define the unit used
Sorry about that. I posted that then went to make a filter and noticed it filled that in. So I tried to delete. I just need to explore more. Thanks for all your replies.
Once you get your MAF errors using STFT+LTFT method, what do you plug in for the corrections when the #'s look like -1, -2, -3, -4, -5, -6, -7, etc?
A lot of people copy/past special, multiply by % in Editor to adjust those cells by those amounts
I prefer doing it mostly by hand so that I can keep things a bit smoother
Is it just LTFT+STFT and MAF frequency that needs to be logged to populate the graph ?
That is correct. But you need to build two graphs, one for the high values and one for the low values.
Thanks for that :)
So, do the math from the error and apply to to the MAF table of frequency vs air flow?
