Ok im gonna see if i can make the dsm ignitor work with the trailing coils due to dsm ignitor are plenty on the salvage yards. if it works i will post how to here soon.
the dsm igniter is similar to the fd igniter but it can only control 2 coils.

 

it won't work with a stock FC ecu, but it should be fine with like a power FC

 

I'm running a megasquirt

 

you should have no trouble. you just need to set the trailing up to fire direct, like an FD
