Random lean condition after shift to third gear

Post by D-Rob » Tue Sep 22, 2015 5:11 pm

Hello,

After tuning a buddy's test mule RDX on E85, I have found that right after the shift to third gear on a 1-2-3 run, the commanded injector pulse is much lower than it should be for a second or two, then richens up in an instant; whereas this is not the case in second gear or fourth gear after the shift.

At first I thought it was because the engine made more than 17psi (where the WOT Compensation table stops natively), so I edited the load index on the last column to 20psi (and made the appropriate changes to the values there), and the same issue exists.

We did not run into this on the dyno (doing third gear runs), and only see it on the street after the 2-3 shift.

Any insight on what I'm seeing here?

Can you disable live tuning and re-test?

Absolutely can.

Disable all live tables I currently have enabled?

It is lean on spool up too. Next step is to disable the secondary o2 sensor.

Yeah, that's a new thing too since it came off the dyno.

Will give that a shot.

Just checked over that file again; the secondary O2 has been disabled the whole time.
