Well i guess ill add what i've found searching...
Bee*r i guess is not specifically not designed for 240" style ignition system
"its designed to be used on ignition systems that use an igniter-rb/sr/jz "
Honestly i thought they were the same exact thing just igniter converts ignition from crank signal....ok i cant explain it but you feel me something like that.
I reviewed some schematics and i guess it interupts the signal sent to the power transiter that supplies the signal for the ground side of the coil. DUH Well if you look at it there are two wires coming from the ecu that go to it. I has like a cylinder looking symbol around them both i think its shielding if i remember. Anyways i dont really know ill have to take it to work and ask around maybe a local shop owner i know. Im not much for electricity at all I CANT EVEN DO PARASIDIC DRAW without remembering to switch my multimeter leads.....POP fuses much
anyways its all good i just put it to 0 yellow knob turns it off so just turn it up at track probly a good thing
