Operation overview
The A/F monitor will simply work off the LC-1 “output 2” as factory set. 0-5

volts is the signal used to send to the A/F Monitor. While the o2 sensor heats up
the Monitor will read full lean. For greater accuracy it is highly reccomened
that a DynoTune Digital A/F gauge be used not this Monitor.
