    4.8 3Bar OS Wont Follow Command BE

    I am stumped as to why this thing wont follow commanded BE tables or PE tables. I set PE AND BE to GM EQ of 1.3 and VCM will not follow those rules. Did that after I realized it wasn't following the PE or BE tables. Had the 2bar OS and everything worked great. Upgraded injectors and went to 3bar OS today and cant get a 11.2 commanded to happen.

    What version are you using of HPT? I tried looking at the file but it wont open. im using 3.6.26 so if your using beta or new 4.0 that might be why. Is your power enrichment table lower than your boost enrichment table?

    something is wrong with your commanded afr channel. if you look at the commanded EQ ratio channel in your log that one is working fine.
    try deleting that channel and adding it back in
