As soon as one of these is cut out for real use on a real vehicle, I will write a decoder for it, and we will have one of the best, if not the best, CAS based RPM and position sensor setups, period, and exclusively.

Thanks to Jammi for drawing it up for us! :-)

Re: FreeEMS Exclusive Decoder
Never linked to this repo that I created at the time: https://github.com/fredcooke/FreeEMS-CAS-HW
Just updated the spreadsheet to reflect something closer to reality.
In summary, the pretty 72 slot variant will not work with a Mazda/Mitsu housing, or any other housing that I know of. Summary:
Will try to convince slackercam to draw these up for us. The old DXFs are more or less useless, sadly.

- 72 Impossible. Literally.
- 56 Unlikely, hard to machine, unlikely to be reliable if it works at all.
- 42 Dubious, might be OK, or not.
- 30 Certainly will work.
- 20 Certainly, but worse.
- 12 Not really better than a DSM disk, not worth the effort.

A few questions:
Is AutoCAD still the industry preference for design submission?
Is there a preferred company in mind for cutting them or just any machine shop one prefers?
What are the specs on the trigger wheel itself (metal gauge, etc.)?
As this is a speciality item (I can't find any companies who emphasize CAS trigger wheels), I'm guessing the first two questions depend on who's doing the machining.

Re: FreeEMS Mazda/Mitsu Exclusive Decoder
DXF is a generic format that 2D cutters are happy to make things from. It's easy enough to design things in it. I did my exhaust manifold flange myself in it years ago.
No specific company, however accuracy will matter. To what extent I'm not yet sure.
Off the top of my head, not sure on thickness, however I have plenty to measure. Stainless steel is the material to use, though.
