Is this wideband standalone?

Yes it is. But you can always hook it up to a stand alone ecm

What exactly is included in the purchase , it seem like the full kit with all cables to instal but i dont see the necessary exhaust bung or wire insul

Yes, this is not included. It is optional, up to your requirements !

Will this product work on a carburetor engine with no ecu? mine is a 1990 corolla with a 4af engine. do i need to buy the exhaust bung and sensor?

Yes as it's a standalone gauge with a ecu reference if you had an ecu. It comes with the sensor and weld in bung

Good product, but ntoe it works differently to the non-plus model

Works great and and the response time and signal level are excellent. Setup with my Miata and a speeduino EFI, it's important to note that this product has no analog signal from the sensor, if you plan to connect this to the ECU, the signal comes from the Gauge. This would be cool, but my little miata didn't have enough power and the gauge was rebooting during crank. Added a voltage stabilizer to resolve that issue and its all good now.
