First MegaSquirt 3 datalog and msq
So last night 
got an MSQ file setup for MS3 without any conflicts. I then promptly stole it and got my car started on it.
Today I modified his msq with my timing settings and put in my fuel and spark tables. I then went out and burned them to my ms3. Car then started up after a few cranks and seemed to idle well. Next on my to-do list is to check and make sure my timing is set correctly and then work on startup settings and tune.
Here are links to my datalog and MSQ files if anyone is interested in looking at them.

MSQ file
I take no responsibility if you use the MSQ and blow your motor.

Hopefully tonight and this weekend I get some road time on the car and can iron out some more bugs with it.

I was simply shooting to get the first Miata running on MS3. Knowing I most likely have the first running one on a car out of the production batch makes me feel even more special. I am going to go get myself a cookie.
Hopefully tonight and this weekend I get some road time on the car and can iron out some more bugs with it.

Scott, it actually doesn't just have a 2-step, but has a 3-step launch with burnout mode.

Edit: I'm also thinking about building a little circuit to convert the TXS output into something MS1 can use. Nothing fancy, just a little 555 timer similar to the one in the MSExtra hardware manual. In the event that it works, I'll post a write up.

Actually starting with MS2 there is software selectable knock input parameters. You could take a TXS knocklite and plug its digital output directly into the MS (at least in theory). Once I upgrade, I plan to test it out.

Got any specifics on the output?
Cheers!

The way I figure it, as long as it is outputting what it sounds like it is, at most the signal might need to be inverted and trigger a timer to hold the line low for a few hundred uS.

You would need to relocate the power filter capacitor, the case would need to be clearanced for the USB port, and it might be a little bit tough to work with the SD card slot, but it looks otherwise easily doable for anyone who wanted to upgrade their MSPNP.
