    Default Commanded fuel limiter

    I was wondering if anyone has figured out a way to get the commanded fuel above 160mm3. I want to push it up to around the EFILive limit of 250 but I seem to be hitting some hidden limiter. When logging it stops at 160mm3 exactly.

    And yes I realize the commanded fuel is basically arbitrary I am trying to limit the light switch effect when boost comes up.

    I think that's just the ecm limits, the CMC goes to 165, and I believe the cmd and cme go to 170.

    Thanks for the info.

    I ended up trying to use the 140-160 region to bring in the over stock fueling end that definitely helped. I had to do a lot of axis table changes.

    I thought about rescaling all the fuel axis by 1/2 or maybe even 1/10 but I'm a little concerned that might cause some unpredictable behavior.
