AEM30-0311 X-Series OBDII Gauge

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 $$.

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.

The media could not be loaded. Awesome gauge to have. Easy to hook up. Easy to setup what setting u want. Super simple & clean looking. Will buy more.

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).

Gauge does not work just flashes obd2 then blank car that it's going in is a 2003 bmw m3.. tried in 3 other cars same thing my guess is its defect getting a new one sent to me so hopfully it works...

Works perfect for my car, tells me everything I need to know. Great Product.

Figure I would try it out, rand everything and to my disappointment the gauge didn’t work. It just says obd 2 then flashes obd 2 again and goes black. Being my car is an 02 with Can OBD 2 I figured it would work just fine. No luck. So to those who buy it plug it in first run the car and make sure it works before you spend the tome doing the install.
