Evo EFI coil

[1997bagger]

M&M efi system on the Evo single fire or dual, can't find any information on the firing system, found reference on all TC's as being single fire.

Next question, if the Evo efi is a duel fire which I think it is, anyone know how to cross to a single fire. If the TC M&M is single fire, will the parts interchange to the Evo firing system?

How many post are on the coil, or how many wires going into the plug?  If it is 2, it's dual fire.  3 or 4 is single.  I think all fi is single.

I'll take a look at the terminals or wires in the plug, appreciate the help

Don't know anything about TCs, but-
Like Hrdtail78 said- A dual fire coil will have two wires connected to it (not counting the plug wires). A single fire coil has 3 (or 4) wires going to it (again, not counting the plug wires).
Can't help you with the interchangeability question.

It is single fire. No question about it.
