EDIS / MS and Stock VW crank sensor

Post by fastback » Sun Apr 12, 2009 5:52 pm

Anyone have used the stock VW crank sensor (instead of the EDIS sensor) together with the EDIS module for Megasquirt /megajolt.?
the sensor is on Mexico cases , WBX and most of the type 4 .
Tried one Stock sensor yesterday , but no signal out of it what so ever.
suspect a broken sensor though :)
The sensor that is used for diagnostic, is it?
In the middle of a project of machining the flywheel to a 36-1 trigger pattern.

The stock sensor was for TDC measurements when hooked up to a diagnostic setup at the dealers.

I want to say it was a VR, but only going by very dusty memory.
To see a signal from a VR, a small current must be running through it, you see a change in the "output".

I'd want something new(er) anyway, there are lots that would work in that location, the one used on later WCVW would work fine, mounts on the front of the block by the flywheel, 9mm hex bolt retains it. IIRC that's a Hall.

thx Pile
The EDIS is also a VR sensor.
We hooked up a multimeter on the EDIS sensor , and it generated a ~1.5-2 V AC and also gave strong signal on the RPM setting.

Toast then.

Does the EDIS sensor fit/reach in the existing hole? (Or reasonably close?)

If you're using EDIS, a VR sensor is the only option.

i'll test a couple of other stock sensors.
the EDIS sensor is long enough and will fit with with a modified bracket.
but it would be cool running the stock sensor /bracket

4 VW sensors later and no signal.
in the meantime my friend mr Thingelstad has machined the flywheel ready.now i "Only" need to assemble the engine and test this solution :)
here's the flywheel and his own way of packing :)

That seems kinda low - my VR sensor with a ford trigger wheel generates 10v peak to peak... and that's at idle. I believe the voltages goes up with RPM. I can't remember the minimum voltage required for EDIS.

that flywheel is HOT. thats what i have plannede for my pickup, not on the pulley end. would rather have that nice and clean looking as opposed to cluttered up with sensors and such.

does that flywheel only go on one way? would the 8 doweled cranks/flywheels be the same, only going on one way?

well we used only and old analogue voltmeter.
maybe we've seen higher voltage on a scope. RMS vs peak etc. :)
the sensor's was tested on a stock EDIS triggerwheel only at a few hundred RPM's.

the WBX and Type4 flywheels have pilot hole making it only fit one way.
i asume the 8 doweling is offset??

Ok.. I was using a scope so that might be why.

We have production run of 36-1 target wheels Type-I Sand/Non-Sand (47mm/50mm).

The pulleys are 148mm for fan drive.

The missing tooth is six (6) teeth ahead of the case "split" area for correct position of the crankshaft sensor.

There is also the bracket, the same as the 60-2 bracket.

Now you just need to make one for the t4 peepz :)

I'm not sure of the alignment on the t1 engine, but does that follow this setup:

Just figured I'd ask...

Thank you for the "peepz", there are other sizes.

We have diameters of 114, 133, 148 mm ALL with a choice of seal diameters of 45mm, 48mm, and 50mm (no seal).

The pulleys all feature "V" belt drive.

Some have "no missing tooth" section for custom position of the sensor bracket. ( just grind one tooth away)

What is your requirement ?

Sorry to jump in in the midst of a thread, but i dont think that is what was asked for. the Type 4 uses a completly diffrent pully attachment system when converted to upright, since you are bolting a pully in place of a fan.

Yeah, I think it would be great if someone made bolt-on trigger wheel setup for the type4 people that was similar to this:

I definitely would have bought it instead of making it myself..
