I have only heat cycled the motor twice. So during the two heat cycles I notice that my commanded AFR is about 14 and my measured is about 12.5 at idle. Background - for initial startup I am running the maf and stock injectors. So this thing should be dead on. I notice that as I give it some gas ( and the timing increases) AFR goes more toward commanded. I will adjust the timing a bit but this may be caused by some issues with the motor which may go away once I break it in. One of the cylinders out of the 4 I compression tested came out quite a bit lower than the rest. So I am hoping that after I break the motor in, that issue goes away.
Any experience with uneven compression and a fresh motor?
