hi i currently working on a coil on plug system for b series motors i got the system to work in a way it is running a 10 deg advance. now i just need to find a way to get the signal from the stock ecu (p28) to the ICM (ignition control module) to control advance on engine load and find a way to get rid of the sensors in the dizzy. so i can remove the dizzy completely. any opinion would help. again im trying to design a system that would work with the stock ecu a plug and play system. thanks

 

dude how in the world did you even get it to run the way you have it now? is each coil firing every 180 degrees?

On OBD I+ cars, the signal wire form the ecu to the ignitor module is a digital signal to control timing and dwell. On Odb 0 cars, the signal wire is actually ground and un-ground for the coil primary, and the ignitor is just a huge transistor.

You can't get rid of "all the sensor sin the distributor". The engine uses the ckp signal to determine that the engine is running, without that sensor, it won't do anything. It also needs the tdc/cyl sensors to determine injector firing order, and the ignition output signal to the Ignitor.

The only way i could think of wiring 4 coils up to the existing system would be to make it a "waste-spark" system that wires all 4 coils up in parallel and use the ignitor ground terminal to fire each coil every 180 degrees (I.E., when cyl 1 is approaching TDC, it gets a spark, and so does cyl 4, which is TDC of exhaust stroke, cyl3 is on BDC of exhaust stroke, and cyl 2 is on BDC of power stroke)

Let me know if you're going to use some sort of aftermarket parts to wire this up. I'm interested
