Default AFR's Still Not Right

Okay, did some reading along with a few emails back and forth from REV.. I am still fighting this AFR Gas Law crap.. I tried re-scaling everything in
the MAT corrections table, and don't get me wrong it helped.. I have increased correction when IAT's are cold, gradually decreasing as the
IAT's warm to a point, then increase
the percentage again gradually as
IAT's warm. This has helped
significantly for major AFR
fluctuations throughout different IAT temps. But I'm fighting this at IDLE
No matter what..... Its either I'm pig rich at idle on cooler mornings and lean as AIT goes up, or visa versa. There is no happy medium, I can correct everything else by playing with the percentages in the MAT table but it drastically effects my idle AFR's and i don't think I should be having to open up my laptop and make IDLE AFR corrections every time the temps change..

Depending on what ECU you have, there is a MAT correction vs load table (not sure that's the correct name, I'm not at my laptop). You could set idle cells to only use 25% or so of the regular MAT correction, and the rest of the table to use 100%.

Also your post is hard to read..
