IAT2 or ???

[killerbee]

IIRC, there is a temp sensor post IC, near the map sensor?

Anyone know what I am talking about? I don't see any pid for it.

[bballer182]

uh don't think so... just at the MAF

[killerbee]

IIRC, the sensor is locate on top of the plenum, just to the left of the turbo compressor.

[bballer182]

found the pid. It's a TCM pid only. "IAT2"

EFI doest say where it's located though.


Guess you could log it and make an assumption.

[killerbee]

Have you seen any IAT2 dependent tables?

[bballer182]

Nope. I'm gunna go log it really quick.

[bballer182]

So that PID caused me about 2 hours of grief. Really long story and it makes me mad to even think about it.

So the pid i think is incorrect once i finally got it to work it read a constant -32*C no matter what i did. boost, no boost. I don't know... gotta report this to the beta section.

The PID for the temp sensor in the cross bridge is SAE.IAT

[killerbee]

Guess I am confused now. Are you saying AAT is measured at the MAF sensor? Based on my logs, I am compelled to believe AAT is taken outside, probably the grill. It is always very close to ambient. SAE.IAT appears to behave exactly like an airbox temp on a relatively dampened CAI.

(thanks for the response!)

AAT is measured at the grill. and the IAT pid is measured at the MAF.

So Josh... this SAE.IAT what is it called in BBL?
