I am noticing that my car has a tendency to get really lean when switching in closed loop, especially when idling. It will hit .98 lambda and then swing all the way to 1.15 before starting to swing back. Is there a way to make it less dramatic and less likely to swing so far lean?

make sure the amplitude is .45 and the hego delay is all 20s

The same entry for all cells for each of those?

yes

Hego sw delay or exhaust pulse hego delay?

For the amplitude do you mean .045 or .45?

pulse

.045

Thanks, Its 1 degree and snowing outside again so it will be a few days before i can test it. Waiting on a TPS too
