Will These coils work with CPR?

Post by beanbooger » Mon Apr 03, 2017 4:05 pm

I have a set of these GM LS2 Truck coils that I'd like to try. They are actually "coil near plug"
(needs to have a short lead). I will make a bracket to fit these above the valve cover on a turbo D16Y8.
Based on the schematic below, would they work? In this case, the sequencer would be the CPR.

Supposedly, these throw a huge spark...

I would not recommend it as it will more than likely cause a lot of interference and be a larger headache.

Sorry, that schematic may have not shown up. Lets try again.

Does the CPR use a 5v signal to fire the coil?

Can you tel me more about the interference concern? Thanks!!

We can't say if it would work without testing them and measuring the electrical characteristics of the LS2 coils (eg trigger current, trigger polarity, back EMF).

The interference is because there still is a plug wire with unknown high frequency damping compared to the coil being right on top of the spark plug and enclosed in a nice grounded steel tube.
