Help Xdi electronic ignition

[Gre@semonkey02]

I’m running electromotive xdi Kit do I need to run a tach adapter for the stock tach or I can just hook it up to the proper wire ? Also does anyone have spark plug wire layout thanks

I ran a simple relay coil adapter to make the tach work. The MSD 8920 might also work. I had the 8920 as a signal for EFI, but it would not run the tach, so I made a simple one from a relay. I will do some searching to see what I did. When I find it I can post it here. Feel free to contact me by IM.

Found the modification...

 

Relay Coil Tach Adapter

 

The one I used was posted by The Witzl. It is pretty easy to make and worked very well.

This is an earlier version of the same ignition. The plug wires are the same on the XDi.

 

 

I ran the XDi for about 6 months using this tach adapter.

 

Hope that this helps.

I use this with my Megasquirt 2 systems. It runs off the signal wire to the coil pack.  I haven't had any issues.

In the manual that I have for XDi one coil fires 1&4 the other 2&3.

That is the way I ran it for 6 months and the previous version for 15 years.

Well why does manual say the right firing order for m10 but your is different?

The manual reads "1st to fire", this is not necessarily cylinder no 1.  It all depends on what cylinder is ready to fire following when the missing teeth gap passes by the VR sensor.   The wheels/pickups are apparently positioned on the engine differently.

(I've run a TecII, TecIII and a GT on M10s in the past.)

My manual says to do like this but I found other picture of someone else and the 4-1 are swapped

1 and 4 no matter because it's waste spark firing.  The importance is that 1 & 4 and 2 & 3 are on common coils.
