MS2e Thermistor Calibration
Greetings. In lieu of a signature, here's the gear involved:
MS2e by Rev
2005 MSM transplant
DIYAutoTune GM IAT installed in stock MSM location (just before TB)
Using the following values for both IAT/CLT:
2490 bias resistor
Both sensors read dead even after the cars been off for 24h. However, at 72* ambient they both read about 56*.
CLT jumps around +/- 10*F at high load/rpms.
IAT reads about ambient during an at temp highway cruise.
Attempts at resolution:
Punched in appropriate values about 100 times as sanity check. No change.
Replaced IAT for *****. No change.
Observed, cleaned engine bay grounds. No change.
Plenty of other threads out there, but those folks seem to have been resolved by punching in the right values, or cleaning up some cabling. I think I'm in the clear on those fronts?
