I have begun to play with both idle and off-idle cylinder fuel trims. I have a fair split at idle and in cells 2,5,6. I have a small split in most of the rest but notice that it stays on one side of the engine. I notice that the stock idle fuel trims are very odd. i.e #1 is 1.03 and #7 is .91 while off-idle is all 1.0's. I know this must offset some characteristic of the intake at idle. Since I have changed my cylinder volume and cam I was not sure that the characteristic was still valid. Does anyone have results from changing these tables?
