That's awesome. I've been pondering this the last couple days. Would you mind drawing up a diagram and maybe a how to? This would be a great helping hand for the Evo community! Good job.

i'm sure you can work out what goes where

and if you can't -
Honda
Power - black/white = 12v
earth - black
signal - multicoloured wires

Mitsi
power - black/white = 12v
earth - black
signal - black/yellow(1+4) black/green(2+3)

Cheers, Mike

Good to hear!

yeah that 2nd pic will work, just make sure the wiring gauge is large enough to flow twice the current (before it tee's off).
i'm not actually sure what 2 or 4 coils would require to run, i ran all my wires as 16gauge, total overkill

ALSO!! did you reuse the stock capacitor or did you install another one?

So with the COP, what gap can you run and what benefits do you think the larger gap will provide ? I have the SpoolnUp COP and am running the stock 9 gap....

I went from stock evo 8 coils with ngk bpr7eix (iirc) iridiums at .024" to spoolinup cop kit with same plugs at .031" and gained an extra 30 miles per tank with no issues boosting.
