Air/Fuel Ratio Gauge - New Design!


Duostyling Air/Fuel Ratio Gauge requires no mounting hardware, senders nor soldering. The gauge uses A3 dummy switch as its housing and the signal is picked up from the existing Oxygen sensor(O2) harness. Plug and play.
Why is air/fuel ratio important?
There are two ways above mentioned ratio can go wrong. Running too rich can destroy catalytic converter, as well as render spark plugs useless. Further more, too much fuel means not all of it burns in the combustion process, so the remaining gasoline washes down the cylinder walls and disolves engine oil, eventually causing low compression due to damaged cylinders and rings. Running too lean can create even worse havoc, especially in force inducted DSCars. Lean is the worst nightmare for owners of turbo and supercharged DSCars. VW engines can handle a lot of boost but only if you supply enough fuel. Most of melted pistons and blown engines are caused by running too lean.

Dual Gauge - Air/Fuel Ratio and Voltage Gauge - great, stock look!!!
Duostyling Air/Fuel Ratio Gauge requires no mounting hardware, senders nor soldering. The gauge uses Corrado dummy switch as its housing and the signal is picked up from the existing Oxygen sensor(O2) harness.

With complementary design to Air/Fuel Ratio Gauge, our Voltage Gauge is the next important instrument. Always know the state of your alternator and battery, especially on those chilly mornings. The signal is picked up from any 12V circuit that comes on with the ignition.

For the best results, you can also install the gauge adding third oxygen sensor (single wire will work). Please consult sources, such as book Maximum Boost or similar.
