| Using EDIS alone, it outputs a fixed spark timing of 10 degrees BTDC. You can drive the car like this! But it won't be very fuel efficient or particularly powerful. Using a relatively simple timing controller ($89 kit) completes the picture. Optionally you can program an entire spark curve map using a standard PC. | Using EDIS alone, it outputs a fixed spark timing of 10 degrees BTDC. You can drive the car like this!

The Ford EDIS (Electronic Distributorless Ignition System) is a computer-controlled ignition system that can operate independent of an ECU. This makes it a great low cost system for swaps. The parts are unbundant in American wrecking yards. The 4-cylinder version of EDIS is used on with 1.9 liter CVH engine in the 1990-1993 Ford Escort and Mercury Tracer, US models. You can make your own crankshaft wheel, or adapt one from the Escort, Mustang, Taurus or other Ford models. Unlike other similar system that require a Camshaft Phase Sensor, this uses a simple crankshaft toothed wheel. It is a wasted spark system. This system has been succesfully used on vintage Beetles, recent BMWs, Datsun Roadsters and just about everything else.
The parts from the wreckers needed are about $25-$100:
- Crank wheel trigger
- Crank sensor
- EDIS module with a bit of the wiring
- 4-tower coil pack
- Spark plug wires
A brand new EDIS module with wiring connector is about $200.
Using EDIS alone, it outputs a fixed spark timing of 10 degrees BTDC. You can drive the car like this! But it won't be very fuel efficient or particularly powerful. Using a relatively simple timing controller ($89 kit) completes the picture. Optionally you can program an entire spark curve map using a standard PC.
MegaJolt Lite Jr Complete kit (MAP sensor option) $89 USD
For detailed technical information, see Ford EDIS technical information
Our own club member sundat1200 has used EDIS on a 1975 VW Rabbit and a 2002 BMW with "great success"
Crank Trigger Wheel
The trigger wheel on the crankshaft has 36 teeth, with one missing -- the 36-1 style. Any wheel of this style can be used.
- You can make your own crankshaft wheel out of sheet metal
- or adapt one from the Escort, Mustang, Taurus or other Ford models
- Ford UK trigger wheel Part No 1078767 is only 13 UK Pounds, and can be glued or bolted to most crank pulleys
For many details, see KEW Engineering
Parts
- FORD EDIS-4 from 1990 Escort/Tracer 1.9L. Part Number: F1CZ-12K072-A
- new Accel 4-Tower coil pack $56.95 at Summit Racing]
