High BAT/IAT/ECT enrichment
Posted: July 18th, 2021, 9:26 am
Is there any table(s) exposed that control the fuel enrichment based on any of the IAT, BAT, ECT or even ambient temperature?
I am targeting specific AFR values which work excellent in normal weather, but with these heat waves hitting all over the planet I noticed that the desired AFRs are about 0.3/0.7 AFR lower (so richer mixture targeted) without having any KR or any weird thing happening (DSC/TC, whatever).
Having the whole setup kind on the limit I didn't want to ride the 100% IDC line for no reason and I did my tuning so that IDC will maybe reach or exceed 100% only if ignition retard values are >0. But now it's hitting 100% sooner because of the 2-5% richer AFRs.
