Product Details

Extra O2 Bung and Plug by Starting Line®. This AutoTune module is another helpful fuel injection tuning aid. How it works is the user programs a target O2 map into the module based on throttle position and RPM. Once it is connected to a PCV with the AutoTune feature turned on, the fueling will self adjust to achieve the target O2 numbers as you ride. Starting Line have found the best results are achieved when running at a constant throttle position (the use of a throttle stop is beneficial to keep the throttle position constant). There are some areas where manual tuning is still mandatory due to other systems that are in place on the factory fuel injection system. SLP has initial O2 map recommendations for you to start with. Please inquire for more detailed information specific to your model.
