Not sure why i'm seeing this.. maybe i'm missing something.. Below screenshot is B7936 (matches B7934 & B7935). I'm don't want the cam phase to change below 3000 RPMs, however when I log GM.INPHAB1, i get the further below map showing the cam phase is changing (GM.INPHEB1 shows 0-0.2). I have disabled AFM in the tune, and that seems to be working fine, but that is the only cam phase table left untouched right now... Tune file is attached. Scan file won't upload due to file size too large. Let me know if I need to email it to someone. If I had to guess it seems to act like there is a table for minimum cam phase angle that I cannot see? I could be wildly wrong there... Just would like to know what is causing the cam phase to not follow these tables.. Thanks in advance.
