99% of the time, it's 14.7. It will of course occasionally fluctuate +/- .1, but that's very rare and to be expected. I should note that this part of my fuel trims has been nailed down for quite some time (cruising between 3250 and 4000 RPM.) The range that led to my CEL was 1750-3000 being a little too lean.

I've been running a 93 map for a weeks now, getting ready for winter. Sad I wish I was running on E85 right now though...

In the spring, I want to look into the open source ECU stuff to make some underlying changes to the ECU that the UTEC cannot handle. Things like eliminating the fuel trims CEL and setting cruise AFR to 15.0:1 or something around there, just to see what (if anything) that gets me.
