    replacing injector drivers in SBEC/2

    Have you replaced injector drivers in your SBEC or SBEC2?
    I developed an easy procedure to get them off the board that I will write up shortly.
    First does any one know what to replace these with.
    They appear to be a 5 pin TO-220-5 MOSFET of some sort. Is something for peak and hold?
    The V6 uses a standard TO-220-3, the 3 pin N-channel MOSFET. I was able to identify this with my "transistor tester" with a Vgs of 1.4V

    I have wondered this for a while. I mean, I know you can get injectors in both types, but I think I remember there is an advantage to the type we *don't* run. The question is, can the other hardware on the board support it?

    Yes the board can support both, look like it is the driver chip (a TO-220 package) and 62 ohm resistor. I hope to verify this over the next month or so
    We use the peak and hold for the low impedance injectors.
