Its actually a very simple device for someone making VR sensors, its just that someone need to fork up the money for the design and tooling. Someone in this case should be Porsche, but they dont want to because they they wont make any money on it probably due to low volumes and they couldnt care less about 931s.

Thats surely the case.
There was one guy who tried the BMW sensor i proposed but with the wrong gap so he didnt get the car running.
If anyone has an S2 car that can be used as the mule, the correct gap needs to be found for the BMW sensor to work..then it should be just a matter of providing the correct spacer.
I was going to develop this but since i got out of the 931 story line i lost interest.

In reality, how many 931 S2's and CGT's are there overall on the road, and how many in need of a sensor annually? Less than 1000 globally on the road at any one time? And less than 20 per year needing a sensor? Not commercial sense for Porsche bean counters given they would have to open tooling with a supplier and have multi hundred minimum order quantity to cover opening and stocking cost.

It would make a little more sense for a small indie to create them, but as I found out trying to get a US guy to make us a solid state FPR, its not easy as everyone doesn't want to waste time and money for small orders, and this would be a circa £80-100 relay, so not cheap.

I get a couple of people a year asking me about my Mittelmotor dizzy and my opinion before purchasing. Usually Ricky as he forgets I told him details already...... :whistle:

Porsche are probably tied in with Bosch, and if Bosch aren't interested, they won't pursue it.

It is a Siemens part and the last one I saw up for sale went for around £125(about 12 months ago).

That sounds familiar. I was guessing.
