    Default E40 2 bar Dyn Air dropping and so is fueling and everything else

    85lb fast injectors (I know they are crap and I told the customer so)
    STS with precision 6265

    After about 4200-4600rpms dyn air drops, so does inj pulsewidth and car goes lean... no matter what i do it always drops

    I have no dips.. i have tried pushing to the max the boost ve table.



    Any thoughts?

    the low gm/S would be due to the the VE being scaled for the 85LB/Hr injectors.

    What's the VE table like?

    Yes it is massively scaled as I kept hitting the limit over and over...

    Injectors are at 37%

    The problem is that the ECU is dropping out of the boost VE table and going back and forth between the main ve and boost ve.

    Any thoughts on how to fix this?

    I had heard of this happening on a car out here. Never figured out what the problem was, so in the end they just made the whole 2bar table the same number (and the last of the 1bar table) and it actually seemed to cure the problem and the car didn't fuel too bad. Not a great solution but it seemed to work.
    I no longer monitor the forum, please either post your question or create a support ticket.

    No matter what OS... same thing... I don't get why it drops from the boost VE table...
