I really really appreciate the info in this thread. Like EO2k, this stuff is well beyond my comprehension and the spoon feeding really helps.
Just to make sure I understand (before I go hacking up my brand new $125 trigger wheel and make it even more useless)... your suggestion is to hack off the 2 "extra" triggers and make it a 12-1, correct?

Can anyone provide me with an accurate diagram of the location of the NB crank sensor relative to the engine / plate, preferably with some info as to how many degrees ATDC the sensor itself is?

I have searched google with every combination of search phrase I can think of but find that only TODA has the triggers. There is the blox that you mentioned, but has gotten bad reviews in other forums. I was just looking to if anyone else had come across other makers.
The performance gain worth the money for the TODA's?

The angle was measured using a 36-1 trigger wheel. From the very top, I counted 11 teeth to the sensor when positioned with a credit card gap (despite what the picture shows, there is indeed a gap).
Since each tooth is 10° from one another, the angle of the sensor would then be 110° ATDC. It can be argued by the poor quality photo that the sensor location is just slightly after 110° but it is within 5° (the angle between the center of the tooth and the center of the gap).
Just as a reference, tooth #1 of the SuperMiata Damper/Trigger wheel is positioned 180° from TDC
Crank at TDC

the 11th tooth falling on the sensor

I hope at least some of this is useful

Can I use the Crank Sensor off my 97 on the 99 I am installing? The part numbers are different and they look different too but I wonder if they are functionally the same.
Also I am going to buy the 99 CAM angle sensor, but cannot find the wiring connector. Does anyone know where I can get one or what type of connector is used?

The '95-'97 cars use a "bare" VR sensor on the crank (literally just a bar magnet with a coil of wire wrapped around it, encased in plastic.) This sensor has a differential output which produces an AC waveform between the Y/B and Y/W wires. The third terminal at the connector is just a shield, and is not functionally active in the circuit (the output signal of the sensor is not referenced to it.)
The '99-'05 crank sensor is a "conditioned" sensor, much like the CAS of the earlier cars. It has an open-collector output which produces a squarewave signal when supplied with an external pullup voltage.
The cam sensor on the '99-'05 cars is electrically identical to the crank sensor.
Here's a link: Yazaki SSD Sealed Connector Series 3 Position Female Housing [Black]
The pins are sold separately: Yazaki SSD Sealed Connector Series Female Terminal 0.3-0.5 mm2 [Tin Plating]
With terminals of this nature, where you don't have the proper crimp tool, it's advisable to buy more than you need, because you will be screwing some of them up. Eg: if you need 3, buy 20. They're quite cheap, right until the point where you run out of them.

Ben, why does diyautotune support the FM wheel when FM doesn't sell Megasquirt ecu's?
I realise it's not diy writing the code, but I'm sure it was diy who asked for the code to be written for FM's wheel.
Why don't you support the oem Mazda 36-2 wheel? It's cheaper then FM's, available from any Mazda dealer and a straight fit on a miata.
For the price of having one FM wheel shipped overhere, I can buy 3 oem's at the local dealership!
