Just curious...
I'm trying to diagnose a intercooler issue on a LT4 CTSV and have been used to looking at IAT 1, 2, and manifold air temp for GEN 5's. The manifold air temp being the one I assumed was like a LSA IAT2 equivalent but calculated instead of actual. Post blower, post intercooler charge temp. This never really sat well with me though because the IAT spark adders and multipliers do not match up with this value.
Today I happened to notice Intake Air Temp B1S1..... to B2S3 (6 total). It looks like B1S3 is post blower/cooler IAT. To try to prove this I unplugged the sensor while scanning and observed no change but did get a IAT B1S3 code.
Anyone else try to log this yet? I'd like to know what is normal. I'd like to see this logged on a bone stock LT4 to see what is appropriate. Manifold air temp was always crazy high compared to what we were seeing on older builds like LSA, magnacharger, etc. I'd assume a normal raw IAT3 for a LT4 would be the same as a LSA IAT2... 100f to maybe 130f normal driving. Would love to know for sure!
Anyone willing to log IAT B1S3 IAT, IAT2 and manifold air temp? would be appreciated !!!
