LC-1 Digital Air/Fuel Ratio (Lambda)  

Sensor Controller Manual 

 
 

 
 
 
 
 

 Warning! 

 

 

The Oxygen Sensor used in this device gets very hot in operation. 
Do not touch the hot sensor.   Do not let a hot sensor touch a 
combustible surface.  Do not use the sensor with or near flammable 
liquids or gases.  Failure to heed these warnings may result in severe 
burns, explosions or fires. 
 
When installed in the exhaust, the oxygen sensor MUST be 
connected and operating with the LC-1 whenever the car is running. 
An un-powered oxygen sensor will be quickly damaged when 
exposed to hot exhaust gases.
