The LambdaKing from RaytechAutomotive is a workshop tool for measuring the oxygen content of exhaust gasses, to enable fine-tuning of the air to fuel ratio (AFR). Featuring the latest LSU 4.9 technology wideband sensor, the LambdaKing is accurate, easy to use and an incredibly economical option for both the professional tuning workshop and the enthusiast.
PETROL, DIESEL, E85, LPG AND METHANOL
The LambdaKing MkII will work with any piston engine running on gasoline, diesel, LPG, Methanol and E85. Whether you’re tuning a single, twin or quad cylinder motorcycle, a petrol V8, turbo diesel 4x4 or track car running on dedicated E85 the LambdaKing will deliver the same ease of use and accurate readings it's renowned for.
VERSATILE SENSOR INSTALL OPTIONS
Included with the LambdaKing is a premium LSU 4.9 wideband sensor, that can be inserted into an existing socket in the vehicle's exhaust system, or via the included weld-on bung. Alternatively, our Sniff Stick tailpipe adapter to place the sensor into the exhaust stream.
IMPROVE THROTTLE RESPONSE, FUEL EFFICIENCY AND OVERALL POWER.
Use the LamdaKing to fine tune the air-fuel mixture in your vehicle, one of the most critical parts of any engine tuning exercise. Optimal air-fuel ratios are the key to good engine performance, throttle response and economy. Running too rich will cost you power, response and economy, while running too lean can endanger your motor with critically high temperatures.
Run your engine smoother, more economically and with higher power output with smart, data driven tuning.
EASY, VISUAL AND ACCURATE READOUTS
The LambdaKing measures oxygen content in the exhaust system in real-time, and so displays current oxygen content in the system - enabling reliable and accurate tuning.
The main numerical display shows the Lambda number within a 0.67 to 6.50 range. The main display can be switched between Lambda and AFR display as preferred with the press of a button.
The sliding bar-graph offer a supplementary at-a-glace display of Lambda within a 0.75 to 3.75 range.
Select the fuel-type from the provided options to allow the LambdaKing to calculate the AFR from the Lambda wideband measurement.
VERSATILE POWER SUPPLY
The LambdaKing MkII runs from the vehicle's electrical power but will accept any 12-14.2V DC supply, and doesn’t require batteries. The LambdaKing MkII comes with a built-in power lead and clamps for connection to the vehicle battery poles. Cable length options are:

Excellent product. It did exactly what I needed to do and was easy to set up
LambdaKing Mk II - Air Fuel Ratio Tuning Meter
There communication and after sales service is bad. I have called and sent emails in regards to a problem I have with the unit but unfortunately they will not return calls or emails. Very disappointing as I am supporting an Australian business and one of this the reason I purchased. Also purchased carburettor balancer and have had no issues with that at all its a great unit so that is also why I purchased agin.
I think you might have missed our message on the 17th of January in response to your query about the sensor being 'a lot larger than anticipated'. If you still require assistance feel free to contact us on firstname.lastname@example.org.
Very easy to use and has really assisted with carby jet tuning. The first unit received was faulty and within 24 hours another replacement unit had been sent out. Support was responsive and easy to deal with. Fantastic to see an aussie product backed up with great customer service.
100% happy with this tool, needed for trouble shooting and checking carburettor vehicles/motorcycles
Very happy with my purchase
