Re: AC idle dips
The calibration is the k20a r set up
Re: AC idle dips
Please post the datalog rather than a screenshot. Probably you need to adjust the amount of air that bypasses the throttle body and then look at the idle duty control.

Re: AC idle dips
Fuel trims are pretty good. o2 sensor might be a little slow to respond, but that is not the problem. I think you just need to check and adjust the amount of air that bypasses the idle controller, and perhaps adjust the duty cycle.

How do I adjust the amount of air that bypasses the idle controller? I know stupid question lol just dont wanna mess anything up.
Re: AC idle dips
First you must unplug the idle controller and set the idle manually at the throttle body at about 550 RPM.
Then all adjustments are made to the idle section of the parameters window in the software.

Re: AC idle dips
Have you tried making changes to the slider for idle valve duty cycle adjustment?
Re: AC idle dips
Do you have a light weight flywheel?
Re: AC idle dips
Yes it's the stock k20a type r flywheel
