is there way to set quicker MAT reading interval in WARI? I highly doubt that my MAT is only +31c (ambient temp was around +5c). This with MP62 without IC (only WI). MAT sensor is some random GM IAT sensor

 

Familiar looking picture that :P

Why do you doubt the temp readings? Because mine are so high? remember 30 minutes on the motorway with a few WOT moments are VERY different to sessions on track. (I doubt on the motorway you were WOT 1st to 4th redline in every gear then slam on the brakes down to 2nd, then back to 4th redline WOT rinse repeat for 20 minutes )

MAT will be read extremely regularly by the ECU, it's a key parameter in working out the fuelling.

 

I guess WI is just this cool :P

for comparison:
without IC or anything = max MAT was 70-80c over ambient
with famous e-cool™ = max MAT 45-50c over ambient
...and now just WI post-blower = 25c over ambient
