anyone tell just by looking?

Im not sure but it looks smart!

Brings me to another question, is there a way of replacing the ford coil pack for coil on plug in a megajolt setup?

cheers lads

@ carl yes but you would still have to have it as a wasted spark settup

Yes but the coils need either built in ignitors or you need one of these http://www.efi-parts.co.uk/index.php?productID=259

This guy has used Ford ones, they look like they'll work and fit perfectly with a little bracketry on a 5 port. http://forums.hybridz.org/topic/97322-edis...illet-aluminum/

Is MJ not stuck with EDIS coils ?

You will not find a COP that is EDIS

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

You still have to use the Edis in conjunction with megajolt, but not the big bulky ford coilpack it seems. I'm willing to give it a go after doing some reading up. Some people use two Edis units, each firing two coils, but some have used one and has been okay.

A single EDIS module should be able to charge two COPs in parallel, it might have a shorter life as the IGBT chips (the high current transistors) will be carrying twice the current when doing so but they are normally well over-rated.

But the COPs must be old style 12V ones.

A lot of modern COPs (or CNPs) are "logic level" devices, ie they have the IGBT built in and a seperate 12V supply and just get commanded by a very low current 5V signal from the ECU. The standard MJ/EDIS combination doesn't do that.... AutoSport do make a unit that does but it isn't the normal EDIS one.

Schrödinger's cat - so which one am I ???

I did notice there were two types, a 3 pin and two pin, so a 2 pin coil is used it should be fine? Sorry for the thread hijacking Brett haha

Yes, Sorry Brett

Carl, your logic is sound but sometimes manufacturers do sneaky things, like a module with two pins might also have a metal sleeved mounting bolt hole which makes the 3rd (ground) connection.

To be certain, choose a donor and look up the car's wiring diagram on the web (worst case buy a CD off ebay, I have the wiring diagrams of every Ford up to 2005 on a CD that cost £1.50 a few years ago) and the wiring diagram will usually make it obvious whether it's a straight coil or a logic driven device.

Okay, thanks for the heads up Rod :)

the edis should be ok i would make sure its mounted correctly onto body though as the mountings are its heatsink

something else to think about though swapping coils on the edis is dwell, the ford coilpacks like a large dwell and its fixed value on the edis module
alot of modern coils run at a much lower dwell value and could potentially over heat
( COPs i have for instance are 0.7-1ms dwell )

I've seen bike engines with two COP wired in series to give you the 'wasted spark'

Now the coils might be specific for that as you are halving the voltage available to both.

I was also led to believe that using two coils on one output was BAD as in essence you have halved the impedance and doubled the current, but the main reason I was told is that it is an increase in transient voltage that kills the output.

You can buy inductive COP's too. Ive seen mention that some motorbikes use them. And inductive can still have 3 wires, although it is more normal to have 2 wires.

TTL coils....usually 3 or 4 wires.

Yes you can wire inductive coils in series, but as above, you will lose power

But more to the point, what engine is this actually for ? Cant see a pencil style coil ever fitting an A-series particularly well.

Plenty of coil near plug options though ?

It'll be for my 1380 T3 build when I eventually get round to it. If you scroll up and have a look at my link to the ford coilpacks they would fit well, I think the key is having a flexible cop and not a rigid one.

The reason I may have a go at it is because IMO it could look a lot tidier, no bulky ht leads, no bulky coilpack to mount and it is just something a little different to try. I am pretty confident that it will work, but if I ever run into a problem, fitting a ford coilpack and leads would be very easy.
