Hello Paul, I tripped over this product while surfing to-day, someone
may find it interesting!

Programmable High Energy Ignition System
Refer Silicon Chip
This is Silicon Chip's most advanced and versatile ignition system yet and
can be used on both two & four stroke engines. The system can be used simply
to intercept and modify the factory ignition timing or turned into a stand
alone ignition system with remapped timing, electronic coil control and
anti-knock sensing. The unit will trigger from a range of sources including
points, Hall effect sensors, optical sensors, or the 5 volt signal from the
car's ECU. Timing can be mapped against engine load and RPM and adjusted in
step as small as 0.5°. Requires KC5386 and WC7502 with all pins connected.

Programmable Ignition System For Cars; Pt.1

Want to program the ignition timing on your car? Now you can, with this
completely new design. It can be used in older cars which presently do not
have electronic ignition or used as an "interceptor" for cars with engine
management systems.

Our previous Programmable Ignition was originally published in March 1996
and proved to be a very popular project with readers. This was subsequently
updated as the Programmable Ignition Timing (PIT) Module in the June and
July 1999 issues of SILICON CHIP.

The updated PIT module included a basic 2-step advance curve and a 1-step
vacuum advance that changed the timing according to engine load. In
operation, it was used to control the High Energy Ignition design from the
June 1998 issue.

This latest Programmable Ignition from SILICON CHIP is far more advanced in
features and its ability to produce an accurate advance curve. It is also a
complete stand-alone ignition system that is triggered by an engine position
sensor and then drives the ignition coil. It can be triggered from one of
many sensors in a distributor, including points, reluctor, Hall effect,
optical trigger and the 5V signal from the car’s Engine Control Unit (ECU).

In order to measure engine load, the Programmable Ignition can use a Sensym
absolute pressure sensor. In fact, provision has been made to mount this
sensor directly on the PC board, the sensor then being connected to the
engine manifold via plastic tubing.

Alternatively, you can connect the ignition circuit to an existing manifold
pressure sensor if present. This is commonly called a Manifold Absolute
Pressure (or MAP) sensor and is found on many cars these days. You could
also use a secondhand MAP sensor from an auto wrecker.

Here is some of the original stuff.
It required the olf fashion coil with out the built in switch like the LS1 or RX8 coils.
