ATV dynotuning

Dynojet 250ix has been designed for testing and tuning of not only motorcycles, but also ATV’s. A second drum allows both rear wheels to turn at the same time. This gives accurate measurements of horsepower and torque. The 250ix also has the ability to put various loads on the engine to simulate different riding conditions. There are two O2 sensors for monitoring the air/fuel ratio. On twin cylinder engines this cuts the testing and tuning in half by being able to monitor both cylinders at the same time.

When an ATV engine is modified the fuel must be adjusted to match the air flow through the engine. Some of the most common components that are changed, is the exhaust and air filter system. Whether it is fuel injected or carbureted the engine will not have the best performance unless the fuel is changed to match the air flow. . This is why a fuel management system is needed to provide correct amount of fuel to match the air flow. On carbureted engines different jets are required. On fuel injected engines some type of fuel management system, such as a power commander is required. Some of these systems come with pre programmed maps that were made for a specific set up. Each engine has its own characteristics and these maps could be made in a part of the country that has different weather conditions. These maps may be close but not give the best performance that could be achieved with a custom built map. With the dyno a custom map can be built that matches the exact set up of the ATV .
