You had me at "180* window".

Unplug injectors, have someone crank while you strobe the crank to check timing.

Any thoughts on where the single-tooth needs to drop in respect to the crank and tooth spacing?

you just need to rotate the CAS so that tooth #1 on your 12-1 wheel is the first tooth to pass the crank sensor after the cam sensor reads the single tooth.

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:
___________ . __________________.___________________.___________ _______.__________

I've read that, it never speaks to where the CMP sensor should drop on a -1 CKP wheel.

yes it does:

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 even easier.

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:
  1. Set engine at TDC
  2. Rotate crank 360*
  3. Make sure CMP/CAS tooth crosses pick-up in the next 300* (missing tooth area reduces CMP window by 60*)
  4. pull the plugs, flood clear, look at the logs, ask MT if it's okay to crank
  5. win at HPDE

But seriously, thanks for all the help. I will buy you beers next time I go to the liberal bee-hive of DC.

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 *****.

This is what I didn't understand from the manual, now I do. I wasn't sure how or where to enter that CMP angle, now I realize that I don't enter it anywhere.
