LambdaKing Mk II - Air Fuel Ratio Tuning Meter

Great addition to my toolbox

I had concerns my engine was running rich. Put the o2 sensor in the exhaust and went for a drive. Got immediate results and peace of mind that the tuning is spot on. Highly recommend.

Very happy with this. It worked extremely well. Took all the guesswork out of tuning twin Hitachi SU carbs Good value for money
