How would this interface with a microsquirt stand alone ecu and on a car pre-obd ii?

Don't get this one. Get the 30-0300, it comes with the complete harness. The 30-0333 is for new cars that can read the sensor off the canbus. Get the 30-0300.

Why does it show pictures of the 30-0311 but states this product is the 30-0344 for “piggy back” capabilities with hp tuners?

Not entirely sure what you mean. My kit came as pictured and works as advertised.

Will this wideband gauge work in “standalone mode”? i have a carbureted vehicle i need to tune and have no use for the obdii connectivity.

Yes. The gauge will display AFR on its own without connecting any of the obdii wiring

Does the digital gauge still work if the obd port is not connected? I would use this wideband for multiple car use not a single install.

Yes. The OBD pass through connector is just to get the information into your data logging software. The sensor reads into the gauge and then sends signal through a separate plug to the OBD port.
