    We should have dyno results wrapped up saturday. I think you guys will be very, very happy


    Our boost fuel patch in action >
    You can see we have total control over the commanded fuel ratio, and resulting AFR. Unlike the stock tables which just goes from 14.7 to "full blast" after a certain throttle angle.
    image 1.jpg

    This AFR commanded is a bit rich (this is on higher boost testing).. but you can see how the AFR will taper down as flow increases.

    vs stock which is just a set value

    What are the x,y,z axis on the 3d table?

    No hints on power yet?

    X = Absolute load
    Y = RPM
    Z = Command fuel compensation (add to)


    Hint: we're over 300ftlbs @ 2300 rpm on 3psi.

    I'm tuning from 3psi to 10psi. This engine loves the boost. However tuning for it is quite tricky, requiring a bit of code.
    But it's running and pulling beautifully.

    Are you doing boost by gear? Perhaps limiting 1st gear to only 3psi for example, and what about when 4lo is being used?

    smashed this, broke that, covered it up with tape and paint

    What is this item?
    Is it a MAF sensor fitting for a auxiliary air box?

    I am wanting to install this in mine this weekend and that looks like the part I’m missing haha

    I can't boost by gear yet, but I can control torque by gear by throttle limiting, but who wants that?

    4Low yes throttle is limited

    Are we getting supercharger numbers this weekend too, or just turbo numbers?

    Will this quench your horsepower thirst for a little bit?
    3-4psi runs,
    85+ ft lbs gain, 85+ whp gain
    This is on a HOT run from this morning.
    This is on the lowest boost setting.
