AFR Question


I was just curious what others are getting for AFR's when cruising at 70 mph.

My WOT is around 12.5, while cruising it bounces around between 14.6 to 15.6, just curious what others are getting on thier gage. The gage I have is an Autometer wideband.

Around 14.7 is normal. You may see some oscillation or hunting of a/f at cruise but 14.7 is what the pcm is shooting for unless you are decelerating. Then fuel shutoff occurs and a/f goes max lean on the gauge.
