90-93 MS3PNP and knock sensor
 

Just got finished wiring my knock sensor in via the expansion plug for my MS3PNP. Knock sensor signal is on Pin B and Sensor ground is Pin A. However I am not sure as how to configure the sensor and the settings in TunerStudio. The sensor is a 2 pin GM knock sensor from a Silverado/Sierra truck. I checked GM Service information for the correct pin out for the connection. I used shielded wire from the sensor to the expansion plug.

What settings do I use for the sensor such as input pin? The link I specified is the information I am going off of. It doesnt specify Analog 3 or Digital 3 etc, just knock sensor. So I am stuck as to what to select in TunerStudio for the correct input pin and how to activate the input pin. Any help is appreciated.

Got it figured out. Called DIY and the sensor input under knock settings should be set to Internal. Hope this helps anyone else with the same concern.

You might have an easier time using a stock nb knock sensor since it fits into a miata engine easily and the settings for those sensors are pretty easily found for megasquirt.
