For the distributor I used a modified to fit, GM 250 Inline 6 HEI distributor. To make it computer controlled I removed the stock ignition control module, vacuum advance and mechancial advance (welded the mechanical advance arms so they would not move) and wired in a 8 pin GM ignition control module that I removed from the vehicle I got the throttle body unit and harness from (a 91 Chevy K1500 pickup with 4.3L V6). The module would not mount in the distributor so I remotely mounted it on the passenger side inner fender (as you can see in the video).

The only sensors used are the
Throttle Position Sensor (TPS)
Idle Air Control Valve (IAC)
Manifold Absolute Pressure Sensor (MAP)
Coolant Temp Sensor (CTS)
Electronic Spark Control Module (ESC) used for the
Knock Sensor
Electronic Timing Control Module (ETC) used for timing
O2 Sensor

No cam or crank sensor is used in this setup. The computer uses the ETC module which sends a pulse to the computer when a plug fires. The computer also uses this pulse to know when to fire the injectors.



Im working on the tech tip and am almost done with it. Its getting to be a few pages long already but I wanted to fill it with as much info as possible.
