Drifting Idle AFRs
I am having an interesting issue. When I start my car, the idle will be at maybe 15:1, then slowly gets richer to about the mid 13's, and after I beat on it a little, it will move all the way to the low 11's. Attached is a short datalog and my tune. Am I missing something here?
My setup: Stock Injectors, DIY MS1 Standalone, LC-1.

Making the four cells around idle all the same helped a bit, but it did not completely solve the issue. I think part of the issue at this point is IAT heatsoak. Idling with tuner studio open, I saw the MAT rise to over 130F, on a 60F day. This car still has the stock airbox & sensor.
