ECUflash EvoScan & 2g STFT & LTFT

[ziggo0]

EvoScan reads Low, Mid & High LTFT. It also reads STFT. I know 1g's have Low, Mid and High fuel trims where as 2g's only have STFT & LTFT. EvoScan has STFT which is fine, but it has 3 LTFT's...High never changes, low easily changes...and mid occasionally changes, when at light acceleration. Which ones do I tune to or pay attention to?

The 2Gs don't use the LTFT High. Just Low and Mid.

Low is idle.

Mid is cruising.

That's what I figured. I'm guessing the Idle & Mid knobs on my maf-t are directly related to those two seeing as they carry the most change.
