MSD box install question
Ok the msd instructions clearly show how to use a box with the large cap efi HEI. But I've already switched to an aftermarket Accel control module from another tpi car I had.
Would you switch back to the stock module or leave the Accel in?
No, do I need msd debates plz, it's a S/S car n I wanna add nitrous sooner or later.

I'm running a MSD 6AL digital box with a large cap HEI distributor. I have always run an ACCEL control module, before and after the MSD box. I have no problems.

Hey BOOT; When you get the thing installed, could you measure the voltage on the "+" side of your ignition coil while it's running?

That's what I've heard, but I'd like someone to confirm that, if possible. Someone said they would in another thread, but never did.

I once had a friend who use to test for spark on his old mustang by just holding a screwdriver in the plug wire and feeling it. Then when another friend had a trans am with HEI we tried to tell him not too, but he insisted. That screwdriver ended up in my wall next to another friends face.

Copy that. I'm not asking you to check that voltage; I'm asking if you would check the primary voltage at the coil....

Try that with a modern DIS system and you might as well tazer yourself.
