Press Release Summary = To calibrate the sensor of the LM-1 the sensor must be operated in free air.
Press Release Body = To calibrate the sensor of the LM-1 the sensor must be operated in free air. On many exhaust systems the 6-8 hrs dissipation time stated in the LM-1 manual is not enough to allow all exhaust gas to dissipate out of the exhaust system. To avoid unscrewing the sensor from the exhaust system for calibration the following trick can be used on EFI cars (and only on those):
Most EFI systems shut off the injectors during coast-down condition as fuel-saving measure. No fuel is injected when the throttle is closed and engine RPM is above 1500 RPM typical. In this condition the engine pumps pure air and therefore quickly purges the exhaust system of remaining exhaust gas. During this condition the LM-1 sensor can be free-air recalibrated. To test your system, first establish a base-line by calibrating the sensor in real free air. Then do a coast-down either on a long downhill stretch or by getting off the throttle after a high-speed run on the freeway (high gear). Check if the LM-1 will read steady 20.9 or 20.8% O2. If so, you can calibrate the LM-1 during coast down. Don\'t get on the throttle while the calibration is in process. If you have to anyway, repeat the calibration until it is finished while you are still coasting down. You can follow the purge process by watching the LM-1. If the displayed number does not change, the system is purged.
