Default Testing 90mm LS2 TB.....
I have an older (2005) LS2 90mm silver blade TB. I'm wondering if it's possible to check it for proper operation at both cold and normal temps? TIA..

The throttle is dumb, the ECU is what alters things based on ECT and IAT sending the Throttle a commanded angle (converted from g/sec airflow etc)

I would be logging throttle angle cold vs hot by reading the ECU PIDs
