I've searched but haven't seen this one. I've got a part throttle defuel that I cannot figure out. It occurs at 45-55% throttle position or so, so accelerating aggressively. The defuel is zeroed out and disabled in the tcm tune. It does not defuel at all at WOT. It's fine at normal accelerating. Just this in-between stuff. I have attached a log. It was speeding up and slowing down so fast I couldn't keep the pedal completely steady, but it's close. I've lowered the pedal torque tables below 60% to at or near stock levels, which still doesn't stop it. I did try resetting taps, no change. Also tried a full tcm flash, but it won't do that, so apparently that isn't available yet for the 6 speeds.

I'm thinking there's some hidden tables in the LMM OS that are being affected, and probably only with the bigger tunes. This is with my new MPI twin setup as an FYI.

Just wondered if any of you have run across a nasty defuel at half throttle or so only, but fine at wot.
