The right EDIS coil pack wiring? (uber simple picture)

[paulc]

Looking for a Yes / No. I searched Google, here, megasquirt forums and couldnt find anything as simple as this - so i made it.

edit: see below for picture.

Not an answer to your question about the plug.
But what you have incircled as coil A - that should be cylinder 1&4, not 1&3. Since either cyl 2 or 3 fire after cyl 1 on a 4cyl engine.
Shouldn't it ?

The coil pack annotations are correct, its a coil pack not a distributor.
A coil pack like this is effectively 2 coils that fire from both ends so when a spark is sent through plug lead to cylinder 1 a wasted spark also goes to plug 3, coil packs usually pair odd and even cylinders together hence 1 + 3 and 2 + 4

Yes, I know that. But at least in my installation - cyl1 and cyl 4 fire together with a wasted spark on cyl 4 when cyl 1 ignites - and same with cyl 2 & cyl 3.

Seems the same as I had mine wired to start with, before fitting the Rev-limit module.
Only thing I did was move the earths/shields to seperate pins, they are all common inside the EDIS unit.


My simple diagram (modified from one on here)

............ patriq is right about the coil labelling being incorrect. one coil fires 1&4, and the other fires 2&3. the above diagram incorrectly says otherwise.

It all depends on the firing order of your engine. Mine is 1-4-3-2, so 1 & 3 are together, as well as 2 & 4. Most inline 4s are 1-3-4-2, so check before you wire it up.

[paulc]

mine is also 1-4-3-2 (VW Type 4)

So, that means that 1 and 3 should fire together and 2 and 4 should fire together? (for this application)

sorry paul, you are correct. i have not come across a motor with that firing order - just my lack of wide experience i guess - and had neglected that possibility.
