What sensors are giving active input - that is affecting the fueling, during closed loop operation...?
Is it solely o2 sensors, and TPS?
What about IAT (inlet air temp)? I find no tables in $DA2.xdf for fuel % vs. IAT.

depending on how you look at things:
TPS(Delta anyways, having it held in one spot doesn't effect fueling at all unless it's far enough to cause PE)
MAP(AE/DE in addition to it's regular job in calculating air mass)
IAT
both O2 sensors
VSS (used in certain masks for AE/DE)
not a sensor, but the carbon cannister can effect fueling.
as far as a IAT compensation table: it's possible when someone went through and made the XDF, they didn't include it for certain reasons. i don't think any A1 XDF had it until i went through and made a complete XDF for it. DA2 could have the same reason.

Ok, I found one table, under $DA2, for MAT Compensation Counts vs. MAT
(manifold air temp = same thing as IAT - inlet air temp)
The compensation counts appear to increase and level out as MAT (measured in degrees C) increases.
Does anyone know what compensation counts affects? (ie. if I change the value, am I adding more fuel or decreasing fuel as manifold air temp increases).
