Is anyone running an MSD with the FC coil directfire? I was wondering how to go about the wiring it up and if it will work.



Thanks, Ed

usual wiring on stock coils except, you will need to eliminate the wires from coming from the FC igniter to the coil. just connect the orange and black to + and - terminals.

Mel, I removed the FC igniter all together and just kept the resistor in place which is hooked up to the - side of the FC coil on one end and to the stock - wire on the other. Then I have the stock + wire going to the + on the FC coil.

Is anyone actually running this set up?

yeah, that how I did my newphew's budget direct fire with MSD. It works fine except, not good enough for me. btw, I used the FC coil without any resistor.

Mel, you like the 3coil set up better? You think I should just remove the resistor?


Thanks, Ed

I am running the 2nd gen leading coil with my 6A in direct fire mode. I love it. The 2nd gen igniter is no longer used as already stated. I do not have the resistor in place which was purely an oversight on my part when I hooked it up but I have never had any problems. I have a spare coil, resistor, and MSD lying around if I ever do have an issue though so I'm not too concerned. I have never tried it with separate coils on the leading but can't imagine it getting too much nicer and I have no intention of changing. It was already a huge difference from the stock setup. When I do change it, it will be to full ignition control through my Megasquirt anyways.

yup, no need for a resistor when using MSD and FC coil. I prefer the 3-coil or DLIDFS over FC direct fire.

Can you quickly clear up why YOU prefer this? I happen to have the fc coil but believe theres something wrong with one side of it, as when I had a running car, on wire wasnt getting signal.

I made comparison using a timing light and 13Btoy confirmed it. As he described it, the light is constant (like a flashlight) on a coil set-up while with the FC, the light is intermitent as in flash, pause, flash, pause. Several months ago, I converted my son's FB and my RX-3 to FC coil , but I wasnt happy as the engine didnt run as hard as before. So I switched back to coil set-up. Maybe its just me but I tried it on 2 cars with similar set-up.
