    There is also a 1 Bar speed density upgrade for some (all?) gen 3 PCMs. This gives you a rpm vs tps adder table to the VE table. That is basiclly gives you a blend of alpha n and SD which id assume...

    I think that the DCFC settings are off and causing the spark dips. Id put back to stock or disable for now.
    IMO BRAF should be:


    176F
    .773lb/min


    212F
    .750lb/min

    Have you verified fuel pressure during start up?

    I would be tempted to just put stock injectors back in with all stock injector values and see if there is still a problem.

    Speaking of injector...

    Positive numbers in the spark idle overspeed table isn't helping.

    Idle airflow is way too high at cold temps and not smooth / random.

    I would start there, closing the throttle body some will raise the IAC counts.

    I would enable the Adaptive Idle Airflow settings, then you will probably have to do some Idle Airflow tuning. Its idling higher then commanded and cant use the IAC valve to help, so its trying to...

    OLSD and outside temperature

    My car runs way richer when its cold outside, like anything less then 60*F. Then it will run normal AFR from ~60*F and higher which is where I tune it.

    For instance today it was ~40*F and my car...

    The fuel>Transient>Min Fuel Milligrams setting as far as I know doesn't have anything directly to do with transient. I don't know why its not under the injector settings. From what I've read all it...

    I would try lowering the fuel>Transient>Min Fuel Milligrams setting, maybe cut in half or even less. I'm thinking the fuel trims are fighting to get the injector pulse lower but the Min Fuel...

    Is it just at idle that's an issue? If so its probably that the fuel>Transient>Min Fuel Milligrams needs to be lowered with injectors that big. I have never personally had to do it, but from what...

    Whats you cam specs (approx)? Are you using a wideband? Still have narrowband O2 sensors? Is your MAF connected? If it is connected, it looks to me it is not disabled in the tune. If that's the...

    I think you were going in the right direction, its just that the massively negative LTIT remembered from the previous tune caused it to stall.

    Does adding to effective area slow down IAC movements because you're telling the pcm that each step is moving more air and therefore doesn't move as far? I haven't messed with this yet but it's on...
