I'll start by warning you this isn't going to happen overnight!
I've started wiring in the auxillary fuseboard along with the relay board, WBO2.
Hardware is as follows
MS2 v3.0
Relay board
VW speedshop crank trigger kit
GM IAT and CLT temp probes
Ford EDIS
Innovate MTX-l LSU4.9
First stage is to get it setup on the 1600 running crank fired ignition...
So far. Live from battery +ve post and fused switched live from the aux fusebox up front. Ground straight to the battery -ve post
Pink goes up front to the yellow from the MTX-l (0V = 7.35 AFR and 5V =
22.39 AFR)
That M6 stud is connected to the -ve post of the battery too, my intention is to run all of the earths to that point (inc.MTX-l earth pictured too)
This cable is shielded... Black is for TACH does white go out to the VR sensor???
Difficult to tell but I need the female half of this plug... Is this the one?

With ms2 and newer there is not much need to use the ford edis module.
Ms1 extra is capable but you have to build more parts.
I use the edis on my ms1. It is a good strong system but you do not get the diagnostic or logging when you have the module/coil driver as a seperate part. |

Thanks VWJetBoat 👍
Hey snu. Yeah I've no idea why I built it this way. It was a college project I built the board for that I kinda lost interest in once I had passed, that was perhaps 6 yrs ago! :/
Also I think I configured it for a HE crank trigger too as when I had it setup first time round I used a hall sensor on a different trigger wheel.
If I remember rightly I installed another BIP373 which is all that is needed to fire 4 coils in 2 batches in wasted spark correct?
You're right I ought to bin the EDIS off...

It sounds like you have set up for direct coil controll.
Bip is a coil driver.
So you do not need the edis module at all.
Can use the ford waste spark coil if you have it.
Or any other coil. Even cop in waste spark.
Or get a quad spark and a cam sensor and go full sequential.
Mario's drop in distributed hole cam sensor looks to be wonderful.
Makes me wish I had not deleted the distributor drive in mine. |

You're jogging my memory a little now... I think you may be right that I have it configured to drive the coils direct from the ECU and just using the EDIS coil. I remember specifically ordering another 373
So now just to rejig for the VR... Is there anyway by looking to confirm that sensor is a VR and not Hall?
I would like a cam sensor, he's not doing another batch now though till next year...

You don't need a cam sensor until you are ready to go full sequential.
If/when you do I would pop out the ms2 daughter and plug in a ms3.
That would give you finer controll, 16x16 tables and smaller increments.
Ms2, waste spark and batch fire will be fine as frogs hair on n/a.
No....i do not know the part numbers for hall vs vr.
I had it in my head that a hall was 3 wire (powered)
And the vr was 2 wire inductive.
I could be wrong though.....research it yourself.
Most of the aftermarket pick ups are hall though. Easier to work with.
Vr is just old and the signal is more difficult to work with. |

Remember mine is in a motorcycle style frame.
I do not have any of the pre fab wiring bits of ms relay board.
I am using the edis module also.
My ford vr was shielded wire. It is hooked to the edis, not to the ms.
The ford coil had 3 wires. One switched plus and the other two were the negative "fire" wires. One for each coil.
Yours will be hooked to the ms.
Download the info and wiring diagrams from the ms site.
Contact the place the new pick up came from and ask for any info on it. |

I have had the ECU powered up and connected to MSdroid with the engine running just to see a Tach signal...
I'm getting 65000 RPM at idle which is a bit beyond even this counterweighted CB crank eh? 
I have twiddled R52 and R56 (Trigger and hysteresis points) to no avail so now I am looking for noise... I think I'll run the shielded cable from DIYA direct from the DB37 as opposed to through the relay board. Good idea?
White from VR to Pin 24
Black from VR to engine ground or Pin 1?

That would only be for the relay cable between the ECU and the relay board.
It is a direct pass through on the D-plugs so no need for different colors.
Mario makes them up that way.

Bypassed the relay board for the tach input from the VR in a quest to minimise noise.
Going to do similar for the two coil outputs too.

I don't know much about the Relay board and the ECU wiring internally but I can't understand why you are butchering the cable to bypass anything.
I ran a VR Sensor on my Ver. 2.2 board for 4 yrs and never had a noise problem.
Are you using twisted pair wires on all your sensors and injectors????
Here is my harness all put together and wrapped into a bundle.
My VR wires aren't even shielded and I have no issues. They are just twisted pair like everything else is.
Everything runs through the Relay board.
