AIR FUEL MIXTURES

Air Fuel ratio analyser testing a R33 GTR showed the vehicle was running very rich, especially at idle. On further investigation the oxygen sensors were faulty.
We use the latest M & W Air Fuel Ratio exhaust analyser to fault find and also to program after market computers and Apexi Super AFC fuel computers to get the ideal air fuel ratio. This is done in real time whilst driving the car on the road. The cars especially the Nissans run way too rich and with the fine tuning they run smoother, more responsive and around 10 to 20KW more power at the wheels whilst using less fuel and not choking up the engine or the environment as much. Also note our technicians are also using Accurate boost gauge and fuel pressure gauge.

We now have the latest high-tech equipment including a 5 gas air fuel ratio exhaust analyzer for accurate real time tuning on road. Large back-lit multi-funtion touch screen. For best performance and response and safety so your car is not running dangerously lean on higher boost. We also use a Pro Tuner device which logs Knock, rpm,boost, and air fuel ratio for accurate and safe tuning. This is used both on our dyno and on the road.
