Would this work on my VX to let me know when I'm in lean burn mode? If it does it'd be worth it to me to put one in, installation sounds easy enough.
It's designed for 0-1 volt narrow-band sensors :
The most commonly used sensor generates its own voltage output, which varies between 0-1 volt. In round terms, if the sensor output is about 0.2 volts or less the mixture is lean, and if the output voltage is over 0.8 volts it is rich. However, the precise value of the output voltage is less important than its relative value - whether it is "richer" or "leaner" than the mid-point voltage.
Your wide-band would be running 0-5 volts. I'll bet if you google around, you can find an LED wiring diagram for a wide-band sensor.
Do you think I could install a narrowband 02 and be able to use the home-made AF gauge to be a real-time signal as to when the car is in lean-burn? Problem is, I wonder how slow the delay would be between the car going in lean-burn and the sensor telling me it's running lean?
