## Description

AEM 30-0311 X-Series OBDII Gauge

Review: Great Gauge - Awesome gauge to have. Easy to hook up. Easy to setup what setting u want. Super simple & clean looking. Will buy more.
Review: Simple and easy to use for 2012+cars - 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...

## Questions & Answers

**Q: Does this continuously use power or does it go to "sleep" so that there is no constant battery drain if the car is not running?**
A: It goes to sleep if engine is not running. Read on AEM website, it has a full info on how it works

**Q: i have a 2006 pontiac solstice. would it read my OBD2?**
A: Yes! Works for your Pontiac! Juts plug and go!

**Q: Will this work on a 2000 bmw e39 5 series?**
A: It will not unfortunately. The CAN protocol that this gauge operates on was not made standard across OEMs until 2008

**Q: Does this include the white faceplate?**
A: Hello thank you for your interest. This does not include the face plate.

### ⭐⭐⭐⭐ Works but needed to modify mine: warning electrical skills may be required
*by P***K on March 14, 2024*

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.
