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
