EDIS/COP question

[357supermagnum]

Can megasquirt controll EDIS/COP wit just a camshaft sensor ?

[8974Ollie]

No, it uses the 36-1 trigger wheel.

[357supermagnum]

No, it uses the 36-1 trigger wheel.

i mistyped, it should have been:

Can megasquirt run EDIS/COP with only a crankshaft sensor ( 36-1 trigger wheel ) ?

[8974Ollie]

Yes.

The coils will be fired in a wasted spark mode but it is doable, at least with Ford coils.

what about doing this on rb25det coils can i use the edis ignitor in example
the wiring going for coil 1&6 (pin 10) go to both 1 & 6 rb single coils or do i have to use the edis or chrysler coil pack
does this make since i would prefer to use my stock rb coils instead of the edis coilpack if possible

[Matt Cramer]

I haven't seen this one tried; unless you've measured the primary resistance and inductance of the RB coils, you'll pretty much have to try this and find out.

[matthunter1448]

primary resistance is .6 to .9

[Matt Cramer]

How about the inductance?

[matthunter1448]

how do i check that?

[Matt Cramer]

The easiest way is with an inductance meter, although those aren't cheap.

[matthunter1448]

know anyone i could send one to to get it checked

Hi there,
you might just connect the non-EDIS ignition coils to the EDIS and see what happens .
I have measured a number of EDIS ignition coils, and they have about 0,52 Ohm resistance (R) and
about 7,7 mH inductance (L).( on the primary side
If you live in the vicinity of a good technical college with an electrical egineering department, they can easily measure the coils you have.
Will take all of 5 minutes once you find the right person.
Since your coil has a higher resistance than the 0,52 EDIS value, saturated current will be lower and the EDIS drivers will not be overloaded.
If it works will depend on the L/R of your coils. EDIS dwell is not accessible or adjustable.
EDIS modules, at least some that I have tested, have built in monitoring of charging current waveform with some kind of shut down
function implemented.
But , the worst that can happen is that EDIS defines the coil as not performing correctly and shut down.
Give it a try!

best regards

Heribert

i guess it's worth a try i just don't want to take the time to wire them all up an it don't work

Just curious if you have tried this yet or found a definitive answer. I have been wondering about this scenario myself, as I would like to use some kind of pencil coil over the stock EDIS style wasted spark coil packs. I was looking into Hyabusa coils, and AEM coils and wondering if they would work with the EDIS module.

is there a difference in f450 cops & mustang cops when running with edis?

[62 f100]

tried with intrepid coil in parallel with no luck & in series i got the led to flash a few times them nothing. going to switch to ford coils but need to know if it matter which car/truck i get them from? on ebay there is some from f450 for $80 for 8.

[8974Ollie]

Does not matter what vehicle the coils come from.
Ford EDIS coils are in groups of 4 or 6. Use 2 ea. 4 coil sets for a V8.
Also the correct control module.

[62 f100]

im talking about coil on plug difference between car & truck.

[8974Ollie]

I believe the EDIS truck and car coils are the same.
