Hi guys, this is on a 5 spd evo 7
3rd gear I'm getting 11.4-11.5
4th gear: 10:9-11:1
5th gear: 10:8-10:9

I too was thinking the same thing...Could you log what loads you hit in the respective gears and then look at fuel map to determine the cause?...I can understand a slight difference, but that is a pretty big swing...Also, I wonder what your 1st and 2nd gear AFR's look like...

Just based on the fuel map, .6 AFR would seem to be a big swing as cij911 says, could it be the change in ignition timing also has an effect? You can get 3 deg between cells, I know the ECU interpolates, but could it have an effect?
