PFC/Datalogit Fuel Issue
The power FC from my
understanding has one set of base maps, and richens the car up the warmer
the intake temp gets, so on hot days when the intake temps get super hot,
its throwing extra fuel at it to keep it safe.
NOW TO MY PROBLEM...
I am getting too much fuel and the car bogs when accelerating from 3K RPM.
Now the real question is ...
is that extra fuel too much, or is the car just getting too damn hot intake
temp wise STILL!
Any advise?

There is a 20X20 base fuel map in milliseconds that controls the injectors.
(1) also a 20X20 fuel correction map to change the base fuel map by a %.
(2) PIM maps to change fuel by RPM or PIM voltage(boost) by a %.
(3) cold start map to add fuel while warming up. by a %.
The above three are accessable with the commander. 1 & 2 are basic way to tune fuel.
Air Temperature vs Injector to change fuel as air density changes. Only accessably by DATALOGIT. Does not make the car richer as air temps go up.
Your assumption is wrong. You need to tune by #1 and/or #2. Time to start studying that PFC manual and read more on this forum.
