Hello,
I've had this issue where the stepper IAC valve opens above the minimum vehicle speed forever with the car. I upgraded the firmware to V1.5.0 so this is now set under "engine state settings".
My car has a VSS in it and the settings are set to keep the IAC closed above 2 mph just as a general setting. The car has a 4-speed so I may push the clutch in before this so once it works correctly, I may need to change the setting. In any case, it tends to open if you're running with the throttle closed for a long period in gear while moving, such as going around a corner or coasting up to a light. I'd like to control this to only when I need it to idle. Please help!
I've attached the MSQ along with a data log.
Thank you!
