Calibration of the WB wideband gauge that Danny and I have is as follows, according to their website:
-Hook red wire on the wiring harness to a positive source and black to ground.
-Plug wiring harness to gauge and oxygen sensor. Sensor is not installed to exhaust yet. It's in open air.
-Turn the positive source on.
-Wait until the gauge shows 19.0.
-Push the button on back of gauge and hold it until it shows A 6.
-Release button and wait for the gauge to read 19.0 again.
-Done, install sensor into exhaust and go brapp around the hood.
