F/S A/F ratio gauge $40.00 plus shipping OBO
I have a dyno tune A/F ratio gauge for sale. I have not posted much on here but have been on the Corvette Forum for over 3 years. (1 NASTY Z) This is brand new and never used with even the bag it was shipped in. If I remember correctly it has the blue back light.
Here is the info from the Website:
The DynoTune Air/Fuel Ratio Gauge is the best made, lightest, most accurate A/F Gauge available. The 100% billet aluminum package is show quality (2-1/16" round). The display options are as follows:
Green or blue backlight LCD display for stunning night time driving. The RED LED display is fantastic and more traditional. All the displays are so good they even work great in direct sunlight lets see those flashing LED models do that!! This A/F gauge works with your existing oxygen sensor!
DynoTune Air/Fuel Gauges are superior to all others because they give you a real oxygen sensor output in millvolts. The DynoTune Gauges work with your existing oxygen sensor. Just three simple wires to hook up.I have tried many of the competition’s Gauges and they don’t even come close to the DynoTune model, Vehicles with Carburetors, Fuel injection, Nitrous, Blowers, Turbo’s, this meter is a must!
