ok, first off i have searched and read until my brain has melted and i feel retarded,
my set up is a 2001 kawasaki zg 1000 concours that is getting fuel injection and gm coils, the question(s) i can't seem to find a good to are: 1) how to properly wire the coils to the MS v3 and also does this only fire 2 (i.e. wasted spark)and not 4 independently?

to ad more i am running a 36-1trigger wheel.

someone PLEASE help!!! i am having a brain melt down!! thanks in advance ~jeff

Jeff,

Did you see this: http://www.useasydocs.com/details/coils.htm ? And this: http://www.useasydocs.com/details/dualspark.htm ?

These are listed in the quick start guide here: http://www.useasydocs.com/quickstart.htm

like i said, my brain is melting, i have looked through all this, maybe i am missing something?
my biggest question is can i run 4 coils and trigger each one individually? or only 2 coils linked together as a "wasted spark"

Last I looked, the standard B&G code only supported 2 spark channels. The MSextra code (click the link at the top of the page; it's a separate forum, so you'll need to register there) allows the use of the ALED and WLED pins as spark channels C & D. You need to add 1k pull-up resistors to 5v to these pins; these can be in the harness, at the coils, or (carefully) inside the uS case itself.

thanks for the help, i think i will just run wasted spark as it should not be an issue, and easier.
