Hopefully a simple question.
In the colder days of winter, I logged my cold start AFR's and corrected the ECT multiplier table A0008, COS5.
I had all the ECT temps from around 15F and up holding at 13.75 AFR.
Now when I go and start the car with 50F plus ambient temps, its holding around 12.5 AFR. Richer than I want.
I am running closed loop/MAF/VE so once it goes into closed loop the trims handle the rest. I am looking for a way to get repeatable cold start AFR in all weather conditions.
Thanks in advance.
