Re: Yet another MSD crank trigger wiring question
There are a few possibilities here.
I am not a fan of the 2 wire magnetic crank sensor when triggering the Holley EFI.
I assume that you are running the timing through the Holley HP ECU.
I prefer the Holley 554-118 Hall Effect Sensor. It uses the same 4X Wheel and Bracket that you already have from MSD.
In the ignition configuration I would look at the settings for the crank sensor and the output to trigger the MSD box. The default signal output is 1.5ms. I have seen boxes that wanted more dwell time for the MSD box to trigger properly. Try 5ms and then 9ms if the 5 doesn't work.
Be sure that the crank sensor if setup to magnetic with the 2 wire MSD sensor and not digital.
Does this engine use a Cam sensor?
