    for MAG 44 blower motor, outlaw

    MSD shows two
    PN 8973 which says banned by NHRA and IHRA
    PN 8971

    we run outlaw so banned is not a problem
    which is best and why is the 8973 banned
    anyone have a one for sale?

    IF RULES ARE NOT A PROBLEM USE A 7569 & A SIX SHOOTER HARNESS 7569 IS USED WITH A P/C OR LAP TOP & IS VERY CHEAP NOT MANY GUYS HAVE EVER HEARD OF IT . USED TO ACTIVATE TIMMING CONTROLLER
    INSTEAD OF A BUNCH OF SWITCHES & TIMERS & U CAN HAVE AS MANY DIFFERENT IGN. MAPS U ,WANT , OR RESET IT IN SECONDS. YOU STILL USE YOUR CHIPS IN THE 6 SHOOTER YOU JUST ARE TURNING EM ON & OFF MORE ACCURATELY,

    the guy from NSA says NHRA and IHRA think the 8973 has traction control built in

    MSD says it don't

    the new one 8971 needs the 7570 programmer but the 8973 don't, it can be done with laptop

    I didn't have him get into the internal differences,

    You can also use the Digital 7 (7531) box to control the mag and get the slew rate rev limiter as well.
