For those with D-Jet, what are you typically seeing for A/F ratio on a medium to hard overrun? Based on what I've read here mine seems too rich - like in 10's and 11's. Once the RPM's drop closer to idle it bounces back up to normal idle A/F ratios. Does A/F on overrun even matter?

My AF seems to stay around 12.-12.5 I believe - depends on how the TPS is set, when I have is supposedly set properly so that I can adjust the mix on the ECU knob it actually goes way up high like 20, so I tweek it just a slight bit so it doesn't do this and then it hangs around the 11-12 something area. - but then its off the idle circuit that allows the idle mix to be set with ecu knob, - stock cam, stock 2.0 motor - I am getting over 30 mpg on freeway driving, @26 in town - Bob you may remember when I brought my car back from Chris's we went for a drive and it was bucking bacd- I replaced that TPS board and its as smooth as can be now- so the board is a good board,
