OK, something isn't quite making sense when calculating AFR. I haven't gotten to the tuning of it yet, and probably won't until I get a wideband.....
But, if I'm reading things correctly, to calculate the AFR being used, I would divide the Stoich AFR (14.7) by the PE Table. The values in my table run from 1.148-1.336. That would give me AFR values from 11.0-12.8. To me, that seems to be running rich. Would running leaner react better? It would have to help the gas mileage. Of course, I didn't by an Avalanche for it's gas mileage - but I would like to increase it a some.....
My VE table is set, my LTFT's are running +2 to -4. So, what, if anything, should I do to adjust the AFR to get it in range? The MAF table is in progess of being tuned, and will hopefully be done this week.
