You already broke out the blue/yellow to the ecu though?

Arg, you guys are talking too much before I get to try anything!!

I twisted the black/white and yellow/blue wires back together, and set tach out to TACHOUT pin, everything is working now. Thank you.

I'm hoping this same change will fix laz. Thanks!

If you want to make it cleaner, you can send the tachout to the black/white and not run the blue/yellow.

God dammit aiden, listen to us.

The yellow/blue wire is already in the harness. It's wrapped and pretty from Mazda from the tach all the way to the ignitor, and now goes along the black/white wire to the ecu. It's not getting any prettier than that.

Haha I thought you added a wire from the blue/yellow all the way to the ecu. I broke out the booze a little early today.

****, didn't load the second page on mobile. Ignore the necro bump.

* Since I already bumped this thread, and it was a great help. Let me aid for anyone in the future wanting to solve this issue, this thread really helped bridge the gap for me.

DIYPNP.

Run pins 4I to TACHOUT inside megasquirt (90-93 cars). Open TunerStudio, go to Tacho output-> ON, select output pin-> TACHOUT, Select speed-> normal.

If you open your Ignitor and solder the joints like I did, there will be no reason to crimp wires. Everything will be ready to go.
This is what your soldered ignitor should look like, probably a better solder job because I am using some shitty equipment.


A horrible diagram of how it is all connected and run. I'll also link a youtube video on me installing them but I do not setup my megasquirt in the video.
