📊 AEM X-Series OBDII Gauge: Ultimate Performance and Efficiency Monitoring Review

The product is good value for money, the pressure gauge is very good, but the downside is that I would like more PID for my car.

I love this sensor. It has so many different features, looks great, is very thin and light making it very easy to install, and there are no splicing or running vacuum lines. Just plug the connector into the OBDII port and you're done.

Everything is fine! The only downside is that my car is a 2021 turbocharged model and the boost option doesn't work (original reason I bought it). It works well, everything else was very easy to install! Since my car is NEW, the sensor does not read all channels.

Image I would try going through everything and to my disappointment the sensor didn't work. It just says obd 2 then flashes obd 2 again and goes black. Since my car is 02 with Can OBD 2 I thought it would work fine. Vain. So for those who buy it, connect it to the machine first and make sure it works before wasting a lot on installation.

Excellent and accurate sensor for PID that you can access. I wanted to access multiple sensors but didn't have the space in a small car, no wiring, cutting or drilling, just plug in and go. The red LED numbers are a bit brighter than my other AEM X-series sensor, but it's tolerable. OBD above, voltmeter below.

This is an amazing little device. Installation took about 20 minutes, most of the time I was trying to route the wire and attach it to the A-pillar at a tricky angle. It's easy to use (if you remember all the shortcuts) and easy to see even in direct sunlight. The wiring harness is very well made, as is the device itself. Which is nice considering the price. worth $$.

When I first read the description of this and some questions I thought it would be a great sensor to add to my turbocharged Outback Onyx XT I knew Already that Subie OBD2 had data for the turbo boost because the OBD app on my phone connected to a good OBD bluetooth device shows it very well and with very little lag. I needed a custom boost sensor so I decided to give it a try. When it arrived and I read the instructions that came with it, it became clear that it didn't support the feature I…

I bought this because I wanted to control AFR on my 04 Rx8. There was little information on the web. It seems like most people install their own aftermarket sensors or don't even try to read the AFR unless their car is supercharged. AFR can easily detect a huge vacuum leak. The condition of the engine is terrible and this gauge gives me added confidence that a loose rubber hose is not going to kill my engine. The pressure gauge itself is quite Finnish. He's the only one on the market like him…
