I still think my UG calibration issues stem from maybe bad O2 sensors(that aren’t throwing codes?), but I did my first calibration last night... corrected the distance up around 6% from what the UG had, and corrected the fuel used, up by like 16%... it corrected the average the UG had for the tank to the 50.36mpg I actually got, and now it seems better...

First thing I noticed was lower instant readings when accelerating... with IAT around 80F, instead of 5th gear accel being at around 20mpg instant, it’s now more like 17-18... my trip home from Flatwoods that went really smoothly and with no forced braking, that would have showed around 70-72mpg avg, now showed like 63...

I *did* friggin nail the first leg of the trip home, averaging almost 100mpg over the approx 6mi though...
