Re: Interesting ignition module with a LT-5 I bought
Electro-Motive, the one-time locomotive manufacuring division of GM, is now owned by Caterpillar.
Electromotive is a long time maker of aftermarket street-performance and racing ignition systems. Usually, people replace OE ignition systems with Electromotive hardware when modifing an engine for racing.

Fastlanes ZR-1 ran this system
The engine management system is Electromotive all controlled by a laptop

Lee,
Did this system tie into the stock ECM? If it does, I'd like to see the wiring.

Re: Interesting ignition module with a LT-5 I bought
The Electromotive HPV-1 system uses 4 coils to fire the plugs. Each coil fires 2 cylinders at a time. The module has 4 set points. The first is for base or initial timing. The second is for advance above 3000 RPM. The third is for a slight advance or retard above 8000 RPM and the 4th is a rev limiter.

Re: Interesting ignition module with a LT-5 I bought
So does this system fire the coils whenever the piston approaching TDC regardless if it's on the compression or exhaust stroke aka "wasted spark" ignition?
