This is something that i have been thinking about as of late. Does the leading coils spark both rotors at the same time, the rotors are out of phase and at different times in the rotation. If it does how does it spark at the same time since the coil is on the same signal one signal say logically one spark. Also is it the same for the trailing? Thanks

There is a "waste" spark right as the rotor is about to pass the leading coil.

 

So it fires at BDC in the exhaust.

 

It seems a little before then, but here is an animation to show how it all works.

Well thanks for the responce i was thinking that maybe there was a delay in the coilsor something. Im hooking up my MSD to my haltech and its already a confusing me and worring me all at the same time so i started to over think.

Thanks
