## Questions & Answers

**Q: Does this kit include the weld in bung?**
A: No, it does not include the weld-in bung. I got mine from the header supplier.

**Q: I'm using it in a boat. How long is the wiring lead. ?**
A: Both wires are about 2m long

**Q: I know my 2011 suburban has two banks but if my exhaust comes off each cylinder head and y’s to one do i really need two wideband controllers?**
A: Two will be more accurate. I just welded bungs on both sides, use one sensor and switch sides if necessary

**Q: How do I calibrate O2 sensor**
A: In order to calibrate the wideband gauge, the sensor needs to be removed from the exhaust and placed in ambient air. Fuel residues present in the exhaust pipe can skew an attempt at recalibrating if the sensor is not removed
