I'm just curious, what CHT's are people seeing for their IO-390? I try to run LOP on most flights and when you set the EMS to lean, you don't see the CHT's. Everything is based on EGT's. If you turn peak detect off then you see it but not when leaning. It wasn't until I downloaded the data file that I could follow the temps and mine are pretty low. I'm curious as to what other people with IO-390's are seeing.
I'm in a Glasair Sportsman.
