30-0311 X-Series OBDII Gauge

Awesome gauge to have. Easy to hook up. Easy to setup what setting u want. Super simple & clean looking. Will buy more.

Easy to use. Best for 2014+ cars due to more data avaliable. Instructions not included. Cord isn't very long but can be extended. Only reads OEM PID's which means its limited by your car manufacturer. Most cars it will read coolant temps, intake, battery volts, codes, RPM etc. Also wideband AFR, oil pressure, fuel pressure if your car stores that info. Only reads 1 thing at a time so its not a multi display. Gotta go to the vendor website for the instructions and code meanings...

They say it has an algorithm in the can bus circuit that can tell when the car is running and when to turn on the gauge since its technically connected to constant power through the OBDII. However in a 2014 chevy sonic, I couldn't get it to start up and shut down reliably so I just de-pinned the power wire from the connector and re-pinned in my own power wire that I tapped from an accessory 12v line. So now the gauge receives its data from the OBDII but it only receives power when the accessory line is on. Minor thing but work I wasn't planning on doing. I also wish this had passthrough since all it should be doing 99% of the time unless you are clearing DTCs is reading the can line. I've run this alongside a tuner using a splitter while data collecting on both, it works for a while but the can signal eventually weakens through the splitter and it fades out and turns off. But all in all when it is turned on and reading data its fairly accurate and helpful. I use it next to my Wideband AFR so I can compare requested lambda to actual lambda while driving.

I was able to plug it into the OBD II port, just like the product said. I got it because my 2022 Volvo has no temperature gauge, which drives me nuts. This unit gives me extremely precise readings of the car's engine coolant temperature. It also gives information on lots of other elements of the engine, but I only use it for the engine coolant temperature. I bought it with the GlowShift Universal Black Single Gauge Swivel Dashboard Pod and it all works well together (although I had to widen the hole in the pod for the very thick rubberized cord that runs from the gauge to the OBD II port).

It’s a good gauge it just didn’t work with my 2002 Silverado 2500hd, but I tried it on my dad’s 2021 Nissan Titan and it worked just fine and looked awesome, all setting working etc. Definitely bummed out but oh well Ill find another option, just wanted something to verify my gauge cluster was working right with my new cam

The ARM AFR gauge that is received looks like an open box or previously used. No foam or bubble wrap of any kind, and no instructions. Just as the way you see in the video.

My car doesn't have a coolant temp guage and is prone to coolant leaks and overheating. This guage allows me to monitor my coolant temp, along with many other things, and even check/clear engine codes! More accurate reading than a temp guage in the radiator hose because the cars temp sensor is in the engine block. Worth every penny!!

This is an awesome little gadget. Took about 20 minutes to install, most of which was me trying to rout r the wire and mount it to my A-pillar at a difficult angle. This is easy to use (once you remember all the gauge reading abbreviations) and easy to see even in direct sunlight. Wire harness feels extremely well made, as does the gauge face itself..which is nice considering the price tag. Worth the $$.

Recomendo

i use for diagnostic tool for reading and repairing bad obd codes

Lo instale en un Gti mk7 y no me marco el boost que es para lo que lo quería , y aparte a la primera limpiada con una microfibra se rayó

Qualitativ hochwertig. Leider nicht mit einem Alfa 159 kompatibel

Ottimo strumento multifunzione, peccato che non legge tutti i protocolli della OBD2. Le OBD2 è uno standard ISO, ma ogni casa automobilistica usa un suo protocollo, i protocolli sono 5. La mia auto è una marca Italiana e usa probabilmente un protocollo europeo, questo strumento non legge questo tipo di protocollo. Evidentemente legge solo il protocollo Americano (statunitense). purtroppo è un grave errore che la AEM Elettronics non abbia pensato ad uno strumento OBD2 compatibile per tutti i protoccoli della presa OBD2.
