Running another 2 stroke twin and I'm finding that I need a slight pause in fueling as I yank the throttle open after some time of near idle condition. Both exhaust gas analyzer show an extremely rich condition until it clears out and the rpm pick up to a steady state.
I noticed you can't apply a negative PW value for accel enrichment. Is this an INI file issue or a firmware issue?
Thanks Ryan.

Re: Negative enrichment during accel
Found the answer to my question. If the PW added or subtracted was a signed 8bit (S08) instead of an unsigned 8 bit (U08) you could have a 4 point line crossing into negative values for a progress decel based on the negative rate which happens to be a signed 16 bit value. Only disadvantage is the max added accell PW would be 12.7ms instead of 25.5 but you could pull up to -12.7 PW out on quick throttle lifts.
PW added can only be positive.
TPSdot can be both positive and negative.
Anyone out there that can make this change in the firmware so I can test this out?
Thanks Ryan
