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?

Did you ever find out any more about this ?
I am also seeing rich AFR numbers on over run, same as yours 10-11 Mine is a 2056 with djet and seems to be similar to your build. running a 043 MPS with initial settings at the 037 specs since I have a 037 ECU, but it was much too lean at those settings. Now I am in the neighborhood of 13.5 - 14.0 at a 3000 rpm cruise but going down hills on over run it goes to the 10.0 - 11.00 range. I did set the throttle switch originally and reset it when I had the throttle body off for another issue. haven't checked the mileage yet and only have about 400 miles on the rebuild engine. |
