Right now I still have a little KR at WOT between 5200 and 6400 RPM. I have multiplied my PE vs RPM by 112% and I'm not sure I should go much farther. I used my MAF table to get my LTrims to around +8 (ported MAF) then I used my IFR table to get them around +3. My car really likes to run a little lean around town and at lower RPM.
I multiplied my PE vs RPM above 2800 RPM I believe.
Anyone go over 112%?

IMHO anytime you muck with MAF table your asking for inconsistant fuel trims, the adaptive stratagy program in the PCM does more then what you can touch via tuning and besides most engines do not need more air, they ping too much from being lean not rich so adding more airflow just makes it worse.
As to PE/RPM, it is simply commanding a richer AFR using the values in that table, do the math and divide the value into 14.7:1 to know what the commanded AFR will be.
Just multiplying a value is just shooting in the breeze when you could enter a known value to command the AFR you want.

What is it multiplying the numbers in the PE table by? VE?
What math do I need to do?
Appreciate the help John.
