Helpful for monitoring your fuel ratio while tuning your car.

I've had the gauge for a while now and still working as expected. Great for helping with tuning your motor or if your running boost or nitrous. It also has two wires that provide 4V linear output to use on your ecu or data logging port.

Good quality

Works as it should, makes tuning your carb a breeze

Good product for gasoline AFR tunning.

This AFR was easy to instal and had great instructions. It's 2 1/16 diameter, which was kind of confusing according to Amazons description. You cannot change the AFR ratio if you're planning to run and type of E50 or E85. Autometer does make a wideband that you can change, but its $100 more. The output is from 0-4v so you can use the wideband output to log AFR in your tuning software. I wish it's output was from 0-5v. That would make tuning a lot more precise and there are alot more math PIDs available.

A good company to do business with.

Have not installed it yet, but I'm confident Autometer has built a good instrument. I will update my experience with it once it is installed.

Nice gauge

Heads up. This is kind of a pain to install. Not for Newbies. Great product otherwise. Looks good. Works good.

Actually works!

Opted to try this gadget to help tune an older carbureted engine. Purchased a sleeve from Glowshift with pre welded O2 bung and was up and going with accurate tune about an hour later. Kicking myself for wasting so much time trying to “ear tune” my old truck at different RPMs.

Great quality

Very nice quality. Nice heavy wiring to sensor and plenty of wire for inside cab hookups. Had a aem first it only lasted 20 minutes. Wish I would have bought the auto meter first. Definitely worth the little extra money.
