On arrival I thought the product was well packaged and looked like a quality product. After welding the supplied plug into the exhaust system, as recommended in the instructions, I warmed up my vehicle then installed the O2 sensor. Then connected the LambdaKing Mk II and restarted the engine to take some readings. The LambdaKing Mk II did not respond as I expected, and it quickly locked in the centre of the dial. The only way to get it to respond was to power it down and then power it up again. It did the same thing again. After much trial and error and re-reading the instructions, I called the manufactures for help. Beware! There is no help given. They would not enter any conversation to help me decide if I had made an error in installation or if I was using the LambdaKing Mk II incorrectly/correctly. They just kept on saying, “If you think it is faulty, return it. We will check it on our test bench. If faulty, we will honour the warranty. If it is the 02 sensor that is on you. No warranty.”
Hello Peter,
Thank you for your feedback.
We are somewhat surprised by your assertion that no help was given, because we spent quite some time on technical support on the phone, during which various fault finding options were discussed. We also discussed a possible warranty repair of your device which was declined.
As we tried to explain, we are not able to remotely determine why your vehicle produced unexpected readings without knowing all the local variables. What we can do is make sure that our products work reliably by 100% function testing each device, and offering a 1 year return to base warranty, which on this occasion was declined. That leaves us without any real options to assist you.
As stated on our website and in your manual, the sensor is warranted is limited to dead-on-arrival cases because it is a wear part that is sensitive to contamination. In this case it did appear that exposure to high levels of unburnt fuel may have been a factor.
