Changing Target Idle Speed
#1 · May 30, 2020, 1:03 pm
I have been running my Go Street EFI 400 now for a few days and I'm thinking of lowering the target idle speed since it idles so much smoother than with the carb. Do I need to reset the IAC Learn when I reset the target idle or will the system just converge on its own?

Your IAC setting will likely change as you lower the RPM. You may still within the limits but you will have to double check.

I would open the Dashboard on the handheld and check the IAC Step count. If it is still within the 3-10 range you are good. If not then adjust accordingly.
