    aight....i have a d16z6......stock bottom and top end....just put my turbo on last weekend and it is just now starting to detinate real bad.

    i have the stock feul injectors, walbro 255lph feul pump, vafc, to a t28 DSM turbo running 10psi. it doesnt detinate till i reach high rpms and floor it.


    i really just dont know how to set the vafc, i also have 450cc DSM injectors but i have yet to put them in....

    you're detonating cuz you don't have any fuel.

    STOP DRIVING THE CAR NOW

    detonation = bad. very bad.

    put the injectors in. its easy enough.

    then, take it to a dyno and have it tuned to roughly 12:1 a/f

    yeah, use the 450 injectors. with that much boost, you need to get more fuel. you shouldn't be reving past 4000 rpms even with the vafc turned completly up. also, the stock fuel pressure regulator might not bee lean enough with 450 injectors, I am using an aem turned a little below stock fuel pressure and still have the vafc tuned to lean on idle. play around with it a little and fugure it out. do you have a a/f gauge. its not the best thing to tune with, but it is betteer then nothing. don't drive it hard until its turned, or kiss the motor goodbye

    As quoted from the autometer site on their a/f gauges:


    Basically what that's telling you is that their gauge is useless at WOT. I really don't know why everyone pulls these so much.

    just curious... how does that have anything to do with this thread? and btw, no one thinks that the autometer type a/f gauges that use the stock o2 sensor are good for anything.
