## Questions & Answers

**Q: How would this interface with a microsquirt stand alone ecu and on a car pre-obd ii?**
A: 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?**
A: 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.**
A: 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.**
A: 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.
