7875 + 5.9 + E85 + Megasquirt

Is this sensor compatible with the MS3? I’ve seen Holley systems had a drop down menu and someone picked the wrong sensor and it would do weird things. Like a Bosch 4.9 being used and the ecu was looking for a 4.2. Just a thought....
I bought this controller and O2 specifically because it has built in support in MS and excellent reviews. https://www.14point7.com/products/spartan

I’m thinking the sensor is just defective.
