Is this the promise land?

then, I just go to the tooth-logger and count the number of teeth and make sure the CMP is dropping just before tooth #1, right? In my case, that's 2-teeth after the space, right?

So the CMP needs to drop between teeth 2 and 3?
Logger should look like:

Tooth #1 is the first tooth to pass the main sensor after the single tooth has passed the second sensor
edit: aw crap, that's the non-missing tooth chart. let me re-read and update the wheel if needed.
acutally, looks like it doesnt matter as long as they dont overlap:
With a missing-tooth main wheel, the missing tooth provides the main position reference to the Megasquirt. The cam signal should occur away (not co-incident with) the missing tooth, the exact angle is irrelevant, so long as they NEVER overlap.

That's what I tried, (quite badly I might add), to say before. The cam position signal can go anywhere really just as long as it doesn't cross the missing tooth.
You basically have almost a full crank revolution to play with.
Hustler, you're making this much harder than it really is

Miataturbo built my hot poz rod.
So basically, my process is:
So basically, my process is:
- Set engine at TDC
- Rotate crank 360*
- Make sure CMP/CAS tooth crosses pick-up in the next 300* (missing tooth area reduces CMP window by 60*)
- pull the plugs, flood clear, look at the logs, ask MT if it's okay to crank
- win at HPDE

Actually. What I would do is make it my bitch. Witness and learn:
I would dremel off the female plastic surrounding the prongs.
Then I would solder wires onto each prong, and heatshrink each wire.
Then I would heatshrink all three of the prongs together (yes i have big heatshrink 8x shrink too)
Then I would junkyard a nice small 3 prong connector, both male and female.
Then I would solder the connector bitch onto the wires on both sides and fluff my *****.
