i am working on my 2017 ZL1. The scanner has this channel (Idle Desired RPM)and it is showing 848rpm at idle in gear. However, i have my Idle Base Setpoint set to 800rpm while in gear and when above 154degrees to 198degrees. So, why is the Idle Desired RPM saying 848 when i am in that temp range? What is bumping up the desired rpm?
