Is the AFX compatible with leaded fuel?
Yes. The AFX welcomes tuning using leaded race fuels. Note however that the sensor deteriorates faster with leaded fuels than with unleaded fuels. The AFX’s proprietary calibration procedure helps extend the sensor’s usable life and maintains accuracy throughout that lifetime. Q: How long of a life can I expect from the sensor? A: The AFX has been designed to extend the AFR sensor’s life as long as possible. However, since sensor life depends on sensor operating conditions, it impossible to predict sensor life without knowing the conditions under which the AFR sensor was used. Therefore, the AFR sensor should be considered an expendable part; a cost of tuning, just like gasoline and your time. Some tuners will never kill a sensor. Some tuners will kill two sensors a race season. You may use the AFX as a constant AFR monitoring tool, but keep in mind that this will consume the sensor faster. If you are not using the sensor to tune the engine, we generally recommend you take it out. It m
