AEM X-Series Wideband UEGO AFR Sensor Controller Gauge with OBDII Connectivity

Q: 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.

Q: 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.

Q: 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

Q: 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.
