Stop in for a cup of coffee

Set it to 6 cylinder, hook to any of the 3 coils, divide by 2? Is it that simple?
Maybe. If my math is right. Lemme think again.
Maybe not.
If it was a single coil on a 3 cyl. dividing the 6 cylinder sale by 2 would be it. right?
But with a single coil it fires 3 times per revolution.
With your coil/cyl. it fires once per cylinder. So then I guess that will read 1/3, so I guess we need to multiply by 3.
does that seem right?
