Here's what I've come to understand so far:
1. Positive% is leaner while Negative% is richer? Seems counter intuitive but ok.
2. LTFT are just a running average of STFT? Does anyone know the sample count for the running average? Mine can jump around a little so I imagine it can't be that long.
3. WOT pulls running rich isn't exactly the end of the world? My STFTs can read up to -25%. I'm guessing this is low fuel quality (E has been testing around 70%), but could there be any other causes?
Ultimately I'm asking what are the safe operating limits of all throttle positions? What are some red flags I need to really be on the lookout for?

-->Light Acceleration
-->Medium Acceleration
