Got a quick question for ya - did yall notice a change in around town driving mileage when you kept the gauge sweeping and out of closed loop (ignoring o2 sensor)? I just put in an AF gauge and my around town mpg went up 1/2mpg or so....

I was like 'huh?'

 

Interesting concept...

My new A/FR gauge smooths out the data so it doesn't swing back and forth, but my old digital one certainly did. And come to think of it, that actually put my foot in it more so that I could check the A/FR at WOT.
