DIM Electronic Advance Ignition

trailbeast,

HEI?
My system is high energy, however it does not use the GM module. The one box system has an internal solid-state switch for the coil, the micro-controller controls dwell and ignition timing. The GM module would be additional parts, wiring, bulk, and expense. There is no need for it.

It is too early for price, that changes much with build quantity. Some depends on how much is included to make it totally plug-and-play. Having the complete harness, coil, distributor, and plug wires, would make a near fool proof install. The components would be excellent quality, and verified to work well with the system.

About a controller.
Your HEI setup uses a mechanical advance distributor, controlling the timing over that, would be a disaster. Good control systems, have a single driver behind the wheel.
