ACCURATE, EASY TO USE AND ECONOMICAL

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, use a third part tailpipe adapter to place the sensor directly 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:

  • Standard - 1900mm
  • Extended 3m - 3000mm
  • Extended 5m - 5000mm

A Lambda blast from the past

This tool has increased my MPG and no soot deposits on the tail pipe, so simple to use. The air that I breath is so much fresher.

I like the idea of no internal Batteries no leaks and who has not got access to a 12 v batt. on their vehicle?

Best tuning tool you can buy!

I diagnosed a problem with a bike that had been running rough within seconds of hooking it up. Takes out all guess work when jetting carby. You can tune your bike to perfection without a dyno! Best buy ever!

LambdaKing Mk II Review

This was the first time I have ever used an AFR gauge, but the instructions were clear and easy to follow. The LambdaKing Mk II is turning out to be a very valuable tool in tuning a project car. The gauge is easy to use and while our car runs on pump gas the gauge can be used with a variety of other fuels if needed.
