Best air/fuel ratio gauge?

[b5blue]

  I'm seeing a wide variety and price spread for A/F meters. If I'm looking to just tweak my Proform 750 jetting can someone give pointers or advice? I know I've got to adapt a bung to the exhaust but I don't plan on keeping the gauge installed. (I'll plug the bung when done.)

AEM UEGO wideband . A great unit, unfortunately like everything else they are going up in price.

For the amount of work needed to install it I personally would leave it hooked up ? It is such a useful tool .

Maybe you could hide it some where ? Glove box maybe ?

I have mine in a 3d printed gauge pod that sits in place of the radio !

I'm not totally happy with this so I am making another. But you get the idea !

The entire center is 3D printed

The quality of those really took a hit when I resized them.... those circular lines should not there weird !

I'm always experimenting with the 3D printer. Good fun.
