Here is a datalog of a 1/4 mile pass from me [finally]. This is a pretty typical run. You will have to zoom in to see the readings. The vertical line to the left of each readings box shows you where on the graphs it is reporting. The shape of the AFR curve is very typical. Fuel pressure is 59 psi. It always has that dip in AFR between 5800 and 6100 RPM.

The 35 degree F rise in IAT during the course of the 1/4 mile run is also very typical. If I start the run at a lower IAT, it will end at a lower IAT. But the temp rise is fairly consistent.

I don't have timing advance on this one, but the OEM timing curve is a disaster. The advance is all over the place, and is not consistent from run to run.
