Ford edis with megajolt - Page 12

All this clunky hardware bolted to the flywheel or inside the mag case to use magnetic sensors which have timing drift with rpm.

Hall Effect= elegantly simple, inexpensive, accurate and reliable.

You can run dual EDIS units from one timing wheel by mounting the second pickup 180 degrees (other side of engine) around the wheel. Then the spark plug leads would be swapped rear to front.

If finding two pickup mount locations 180 degrees apart is problematic, you can mount Ign#2 pickup 15 degrees before ign #1 pickup. Then, like most mag setups, you always start the engine on #1 ignition only. At cranking speed Ign #1 will fire near TDC, while ign #2 will fire near 15 deg BTDC.

Once running, the EDIS advances 10 degrees at around 400 rpm, resulting in 10 fixed advance for ign #1 and 25 degree fixed advance for ign#2. Megajolt can be connected to ign#1 with 0 degrees pickup alignment correction and run an appropriate advance map. Megajolt #2 can be set with a 15 degree pickup alignment offset and run the same advance map. Pickup alignment can be adjusted electronically in Megajolt up to 30 degrees either direction.

Kirk;
I like your thinking re; 15 degree sensor offset. Would work as a passive fixed 25 degree advanced with Megajolt failure too.
I have a Pmag on the left side. It replaced a Bendix 200 Shower of Sparks combination that was making radio noise in flight.
The other Bendix (on the right side) is running fine, but I've accumulated a pile of EDIS parts, and I like the trigger wheel inside the pulley idea presented on this thread.
FINALLY there is enough forum interest for EDIS to approach 'Critical Mass'.
Get several great minds on a project and watch it grow!
Who is having a "inside the small diameter pulley" 36-1 timing wheel made? Want to make a few and share costs?
I have a large pulley flywheel on my T-18, so I might be interested in an inside the pulley timing wheel for it, should that be my only choice...

Sort of a long distance trade, but Graham ("Airtractor8", above) might be happy to swap EDIS modules for wheels. Trust me

I had an inside ring for the large pulley made yesterday at the local Water Jet shop.
It was easy with Dan's Cad drawing

I did have them increase the OD to 8"to allow enough meat on the edge for me to countersink the holes for 8/32 screws. Made it from .125 Mild Steel. It cost me all of $37

Will probably get it plated before fitting.

Here is a test fit on a flywheel I found lying around. The hole centres line up right in the middle of the flange bosses and it has just the right amount of clearance from the radius on the inside of the pulley.

As far as sourcing EDIS components are concerned, I am having a lot of trouble finding a 4 cylinder 12 pin module connector plug.
Does anyone know where I can get a new one? There seems to be plenty of the 8 cylinder type but these won't fit. The keyways are different.
I managed to get a module of ebay and it seems that the reluctor plug and coil plug are plentiful but non genuine.
I would go to the Wrecking yard for a used one but this system was not fitted to Aussie cars unfortunately

I used a 6 cylinder plug on a 4 cylinder EDIS. It has all the right pins and it clips securely in place. Just trim the key tabs from the ends of the plug. Use a little more care when assembling connector to module. Once it snaps in place it ain't going anywhere.
