Use Narrowband sensor with ms?
 

For the stock narrow band one wire sensor and MS, is the wire just a voltage wire coming out of the O2 sensor that I can hook directly into the megasquirt with no issues? Anyone know off hand?

I've got a MSPnP.
In MegaTune, i can see the narrowband activity. I didn't make any wiring.

I think you can't connect directly, you must use the engine wire harness.

Did you try checking the manual?

But yes, you can plug the NB sensor directly to the MS. Just make sure to configure your tuning software and the firmware that you have a NB hooked up.
