Rice Racing M&W CDI COP Set-up

The CDI box sends the DON MEGA high voltage to the low resistance CDI specific coils, the coils act as a step up transformer amplifying the voltage to INSANE levels. This process is super fast!... NOTE: it still takes time to build up the 'power' in the Capacitors and this is why even with multi channel boxes you need a certain minimum time between firing events to make the full rated capacity of that specific CDI box. For the M&W rotary box it can only do this on a sequential 4 channel ECU sending even spaced spark events out of the ECU (IE Apexi PFC does not do this on Leading plugs).

It IGN-1A uses inductance and takes time to build up the primary side voltage and current to a level that is acceptable enough, then as this field collapses it induces a secondary high voltage through magnetic inductance in the secondary winding of the coil, its a slow ass process, that is very dependent on 'dwell' or charge time. IF you don't have enough time to build up the charge then the c-u-n-t-s have very low power and will misfire, so cant be used on wasted spark engines (OEM and PFC), and they always struggle at high RPM due to the proportional loss of dwell time available to build up sufficient energy through this slow ass process...... this is why the c-u-n-t-s are shit on 2 stroke / WANKEL high rev applications as there is such low time between firing events ........... hope this makes sense?

Yes.. so its for speed and strength of the spark the coil is giving. So it would work fine with out the CDI box if it was run on a standalone system like Haltech?

Haltech (only one that cant is the PFC) can use the IGN-1A effectively, yes.

gotcha. Well... eventually ill be very interested

as soon as I'm ready to get the engine all built up. I'm working on getting the rest of the car ready to receive the good ol engine.

by the way .. your use of the term "donmega" makes me giggle. I assume it means "awesome" but i like it

I coined the term eons ago, its derived from the 'megladon' which is a big fuck off shark that rules the ocean, I thought it sounded catchy so reversed the saying to Don Mega!
Been using it everywhere since haha.

Almost ready !!!!! Want some ?????
