I have seen the twin spark dizzies. Straight forward.

Then there are the crank fire twin pack setups. ok.


what else can be used?
Piggyback systems?

EDIS-4 90-93 4cyl models, this info came from the Megasquirt website, MS11 ignition .
Tells all about setting up the VR sensor and trigger wheel.

EDIS-4, 1990 to 1993 1.9L 4 cylinder engines. Ford Escort, and i think Mercury Lynx.

Grab the trigger wheel, the VR sensor, the module, the coil and as much of the wiring harness as possible. In patricular, the wiring from the sensor to the module and from the module to ECU are shielded. Also the connectors are important.

How are you going to do it? A Milling machine?

I would like to see it when you are done.

what about orientation?

doesnt it matter where the missing tooth goes? ie... it dictates where you need to put your sensor?

and the fan only goes on one way right?

i have an extra fan i think i could donate to the cause

sensor position would need to be decided first, based on mounting surfaces.
Then you would want it to have a bit of adjustment for fine tuning i'm guessing.

is the big notch TDC? or?

set crank to desired position, mark the fan where you want the big notch to fall with respect to the sensor.


I had though it would be cool to mount the sensor in the timing access hole.
incorporated into a screw in device to replace the plug.

I have a fan with two busted blades I could play with.

the toothed fan doesnt mean twin blug... you can utilize that for ANY crank fire system.....

big red line/notch on fan is TDC iirc....

doesn't the gap have to be at a certain position?
is it reading TDC or just revolutions?

but i have no experience with edis/crankfire/sds/megasquirt
