Motec - going from 1 coil to 8

[damage]

I guess it depends on how long you want your coils to last as far as I'm aware if you run wasted spark through a CDI coil set up it overheats the coils and you end up with capacitor failure and or premature coil failure, the other issue is excess temperature also causes spark break down.

I suppose it's a budget toss up as to what's worth more replacement coils or the expander unit.

The other option you can also look at if a cam sensor is an issue is 2 opposing crank sensors and then tell the computer what it needs to listen too.

To be honest we couldn't ever run wasted spark on 2 stroke applications at all so I haven't had a great deal to do with it.

If you set them up correct on CDI I know they will run 15,000 rpm and never miss a beat. A pulse input of 350-400 volts to the Mercury coils produces a nice fat 40,000 volt spark so you know your alive when those suckers bite you.
