A 12mm wrench will remove the CAS bolts.

I just grabbed one off a 6cyl DSM at the junkyard (all the 4 cylinder cars were stripped), the sensor has the same numbers on it as the one pictured. Just wanted to put it out there.

No such thing as a 6 cylinder DSM. A 6 cylinder Mitsubishi CAS look like this:



None of the 6cyl Mitsubishi's used a CAS identical to the four cylinder cars. Mounting is much different as well. These sensors are not a direct replacement for what's documented in this thread.

It sure looked like a DSM but I'm no rice expert. I can't see the one you posted but it looks nearly identical to the one in the first post and has "T1T49371 R" and "OY24" on it.

(edit)

Just from that picture I can see that the mounting is different and that the body dia is bigger and longer. Better pay more attention to your "rice". DSMs are built in Normal, IL BTW.

Oh well, I guess I'll sell it on ebay and try to find a 4cyl that hasn't been stripped. The CAS I have came off a 3000GT, which I thought was a DSM but apparently it isn't. I knew DSMs were American built, BTW. I call them rice because most of them are riced around here, including the ones I see in the junkyard. Very rarely do I see a DSM that is actually fast.

The final part, ecu configuration, will be done very soon. It's a difficult section to write since there's a plethora of different MS setups out there. I'm trying to keep the documentation as specific as possible to try and cover everything without writing a novel.

I'll have it up by the end of the weekend.

actually the sensor part of it is, the shell and the mechanical means to make it work, however, are not.

that's really just a longwinded way to say "hang on to it" since the senor part of it will interchange.

yep. I thought I posted about that elsewhere? I grabbed a v6 cas so I'd have a spare pickup setup.

I know that. For all intents and purposes of this manual, and to try and reach an audience with a broad range of mechanical aptitudes, I'd like to keep it focused on what works with Josh's adapter.

While poking around at the shop today, I noticed that the earlier miatas with no head mounted ignition coil pack indeed have a DSM cas.

The unit was out sitting on the bench, and it had a mitsubishi insignia on it. I was not allowed to open the unit to my dismay and inspect to see if it was indeed optical or magnetic.

Again, the internals are going to be the same. Same disk, same sensor different housing and different mounts.

What's next, people coming on and telling us that SR20's have DSM CAS' too? Just because it has a Mitsubishi logo does not mean it is for sure a DSM CAS.

Mine has "MANDO" written on all the parts instead of the Mitsubishi logo.

No. MS simply looks at where the cam tooth is and considers the next crank tooth "tooth 1." The position of the crank teeth have not changed therefore timing will not be affected.
