The 9 Best OBD2 Gauge Displays
This wiki has been updated 27 times since it was first published in December of 2018. Your dashboard can give you plenty of information about the health of your engine, but if you want to go even more in-depth, you'll need one of these OBD2 gauge displays. They plug into your onboard diagnostics system to monitor everything from speed to fuel efficiency, while also warning you if there are any problems. You can use them to understand and clear fault codes as well. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki.

Editor's Notes
February 26, 2021:
Note that most options do have a speed offset – that is they show a higher speed of about 5mph in most cases – in order to ‘encourage’ you to slow down. This is done in the interest of safety, but can obviously be adjusted.
I’ve removed options like the BlueDriver Professional and PLX Devices Kiwi 3, because I really feel like they belong in our list of the best obd2 scanners and not so much here. Of course, most gauges also offer diagnostics nowadays, but they’re definitely designed with the primary intention of displaying a gauge. OBD2 Gauges like the VGEBY Projector and Arestech A8 reflect onto the windscreen while most others are mounted options. Both have their unique advantages, though you may find the windscreen-reflected options take a little getting used to.

All of the options on this list should be fairly easy to install, as most are plug-and-play models. The primary decision users need to make is how they want to get the information — whether they want to read it off their phones, have it displayed on their windshield, or shown on the device itself. It's a personal decision, and one that should be made with your safety in mind. Whichever one is least likely to take your eyes off the road is probably best for you.

Kaivaan grew up in a little town called York in the north of England, though he was whisked off to sunny Jamaica at the age of 14, where he attended high school. After graduating, he returned to the UK to study electronic engineering at the University of Warwick, where he became the chief editor for the engineering society’s flagship magazine. A couple of uninspiring internships in engineering later however, and after some time spent soul-searching and traveling across Asia and East Africa, he he now lives and works in in Dubai.
