I do not have an AFPR.

I turned off closed loop operation by making my TPS crossover points 0 for
tuning my fuel map purposes. That way if it's hitting 14.7 at idle and cruise I
know I'm in the general vicinity of correctness and my ECU isn't tuning itself
while I'm making changes. Once I get everything ironed out I'll turn closed loop
operation back on. So, to answer your question my fuel trims are at 100%. LOL

I guess I'll add one more notch to the global to richen it up a little bit more
and mess with the deadtimes.

Thanks,
Andrew

finetune? If not, I prefer not to play around with the airflow compensation, but
use the deadtime instead if you can. What are your fueltrims doing? That is how
I like to tune the closedloop operation.

have properly compensated for everything. I've got the fuel map setup for about
11.0:1. But, when I do a pull a WOT log I get right where I want to be at about
11.5-11.8AFR all the way through. So, what I did was drop the global injector
compensation down from 650 to 637 to richen up my openloop map overall. Then,
took some MAF compensation out in the 0-100hz range to lean out the idle and
cruise.

how can I add fuel via the MAF comp scale above that level? Or does anything I
add to the 1600hz MAF comp scale affect readings higher than that? Since I'm
pulling about 2100-2200hz based on my logs.
