first off, I am just learning by seat of the pants so excuse me if the following is totally off. TMAF= temperature mass air flow?
If what you've pointed out is true:
1) why would TMAF have high correlation with RPM/Load etc? as you say the location is pre - SC.
2) How can this temperature be consistantly higher than that of the post SC/pre IC temps?
Searched around found this link. Pinout 18 TMAF - IAT ground and 31 TMAF - MAF ground. May be there are 2...
