The Interceptor Ignition from RetroMotion Innovations works by "intercepting" the trigger signal between the distributor and the coil, allowing digital control of centrifugal and vacuum advance. You can keep your vehicle appearance completely original as the unit can be easily hidden under the dash. On most classic cars, Interceptor connects directly to the stock (non high-energy) coil. It can be used with high energy coils if installed in conjunction with an aftermarket ignition amplifier.
Interceptor is available in both vacuum and boost versions. Dwell is automatically calculated to combine strong sparks at all times with minimum load on your coil. The dwell angle can be entered manually if preferred.
The first step is to lock your current distributor to disable it's mechanical advance, to allow Interceptor to have complete control of the timing curve. After installation and wiring, the software can be used to adjust all timing characteristics, set a rev limit etc. We encourage you to download the software to your PC right now and try it out!
