Wiring DIYAutoTune Crank Sensor on MicroSquirt v2.2

[jfbrink]

Hello,

I have a MicroSquirt V2.2 based ECU (it is the Generic Plug-n-Play unit that Stratified Tuning used to sell).

I would like to use DIYAutoTune's hall effect crank sensor with it; it has a built in pull-down resistor.

But, this is the extent of their instructions for my board: "older MicroSquirts will need to use the Hall effect input".

Does that mean that I should be connecting my signal wire from their crank sensor to OPTO-?

Thanks,

Jesse.

Yes, connect it to Opto.

This is a simplified diagram of how I did mine:
