New DynoTune Air/Fuel Ratio Gauge.
It will come new in the box with installation and tuning instructions plus everything you need to install into your vehicle. It works off your Existing factory oxygen sensor. This auction is for one standard square key-Chain sized package where it can be mounted anywhere.It will come with the Red LED display.
A quality Gauge with unmatched performance!
The DynoTune Air/Fuel Ratio Gauge is one of the smallest, lightest, most accurate A/F Gauge available. The superior Digital Display is available in Red LED Display for a more traditional look. The display can be seen in direct sunlight, lets see those flashing LED models do that!
All the DynoTune A/F Gauges work with your existing oxygen sensor!
NOTE: Only works on 0-1 Volt Oxygen sensors, may not work on volkswagon and some hondas. Check with your shop manual to make sure you have the 0-1 Volt oxygen sensor output(Most Vehicles do).
DynoTune Air/Fuel Gauges are superior to all others because they give you a real oxygen sensor output in millvolts. 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 Gauge is a must!
Yes this will work great with Carburetors Also. You need to weld in a “Bung” or nut into the header at the collector junction. Screw in the oxygen sensor and wire up the three wires on the gauge and you are done. This will allow you to tune for wide open throttle or cruise. You can use it to tune for cruise as well but it takes some practice reading the display. With a perfect 14.7 to 1 A/F ratio the display will cycle up and down
example Case #1 “ .800 .300 .750 .250 .850 .200 etc…”
This is the perfect example of the perfect ratio.
Now if you see this “ .900 .750 .800 .700 .900 etc….” this would tell you your running rich during cruise.
If you see it run on the other end as follows “.300 .250 .400 .500 .375 etc….” Your running lean during cruise. You make adjustments to jets or fuel pressure to make sure the display cycles as in case #1.
Running wide open throttle should result in readings as follows “.900 .905 .908 .910 .911 .911 etc…” it should be very stable! No jumping around, rock solid….

Lada is set to relaunch in western Europe - including the UK - by 2012-2013 to counter the threat of Chinese car makers, senior sources admitted last night. Renault's global marketing senior vice president, Stephen Norman, told CAR that Renault-Nissan's stake in Russian firm AvtoVaz would help bring about the return of Lada to Britain. 'The UK is one of the few markets where Lada was a success,' said Norman.
