Power Commander/Juicebox Baseline Percentage Adjustment Question
I used a stock dyno chart from this board to see where the lean/rich areas throughout the RPM range on our 250 is. I adjusted based on the visual from the charts available online. I only made major adjustments in the 40,60,80, and 100 % throttle range, and in 250 RPM increments.
Bottom End: At the leanest portion of a/f ratio (2-3750k), i added 14-11% (respectively) to compensate.
Mid Range: between 5-9000k, i tapered from 11-8% to compensate for the lean conditions.
Top End: between 9-10.5k, i reduced the fuel from -1%, -4% (respectively) to compensate for the rich conditions.
BIG QUESTION: for those of you who've dyno'd & tuned... (if you're willing to share), what is the baseline above stock where you make fuel delivery adjustments from (assuming stock is 0%+/-)?
Bike is running stronger than stock (revs up a lot quicker), but I'm still curious.
