No knock in the FLKC table but I'm still not 100% on the A/F Learning table. Can anyone lay it out for me?
AF#1 is long term fuel trims divided up into 'zones
So under 5.6 is idle
5.6 to 9 is initial take off
9-40 is generally cruise
40 to 80 is the important one. It self learns between 40 and 80 to add or subtract fuel to get the MAF scaling onto target as it blends into open loop. The thing with this is that what ever it learsn, sat +5% is then applied from 40g/sec to the end of the MAF voltage range. So it adds 5% fuel or roughly 0.7 AFR to the entire MAF scale
Nothing to be worried by those values
You want the 4th range as close to zero as possible and the others are all trying to get optimal cruise AFR's
