OBDLink® MX is a budget-priced, pocket-size Bluetooth OBD-II adapter for all OBD-II compliant vehicles (except hybrid or electric vehicles). It can be used as a diagnostic scan tool, trip computer, logger, and real-time performance monitor. OBDLink® MX surpassed performance in every competing Bluetooth OBD-II adapter, delivering 300% more data samples per second. Its BatterySaver™ sleep mode allows the adapter to stay plugged in continually, without draining the vehicle’s battery.
Unlike the vast majority of Bluetooth OBD adapters, which constantly broadcast their presence and use an easy-to-guess 4-digit PIN, OBDLink® MX utilizes a unique multi-layered link security mechanism, eliminating the risk of unauthorized access. OBDLink MX’s support of the de facto standard ELM327 command set, makes it compatible with tons of third-party OBD software and mobile apps.
OBDwiz and OBDLink app, included with OBDLink® MX, allow you to:
- Turn off the check engine light, and erase stored diagnostic information
- Read and erase stored, pending, and permanent trouble codes (both generic and manufacturer-specific)
- Access freeze frame information
- Display, graph, and log 90+ real-time parameters
- Create custom digital dashboards
- Measure and display fuel economy
- And much more!

I've bought and used the cheaper OBDII units and they are fine if you only want standard and clitchy results. I came across ScanTool.net when looking for some tools and found the OBDLink MX and bought it with out even consideration of cost(fed up with poor quality products). It has been the best money I've ever spent. I use it every day on all different type's of cars for different reasons. And i couldn't be happier with it. A big thanks to the team at ScanTool.netSatisfaction

I bought the OBDLink a few years ago and didn't really use it that much because it couldn't read codes from all the modules in my car and it required a computer to connect with. For the most part, my old OBDLink just sat in a drawer collecting dust. I discovered the Torque Android app recently, and decided that I would try to add Bluetooth to my old OBDLink and keep it in my car. I contacted ScanTool.net to get Bluetooth added to my device, and while I was perusing their website I came across the OBDLink MX.Satisfaction
The OBDLink MX solves many of the issues that I would have had a hard time dealing with after adding Bluetooth to my old OBDLink. Namely, the MX goes to sleep automatically after you turn the car off (I would have had to manually unplug the old OBDLink), it supports an additional CAN protocol that my vehicle uses, it's small and has no wires that need hiding like my old OBDLink, it supports faster data rates than the OBDLink, and the Bluetooth protocol is far more secure, so I don't have to worry about some dude pulling up next to me and fiddling with my ECU.
ScanTool.net allowed me to trade in my old OBDLink for a significantly reduced price on the OBDLink MX. I made the swap and I couldn't be happier. I have the device connected 24/7 in my car and Torque Pro on my smartphone. I have a server running this guy's code (http://torque.ip.v6.me.uk/) at home and Torque will send logs from my car directly to my home server. I can then pull up any of my trip logs at home and views things like boost pressure, G-forces, speed, and mpg at any instant during my trip plotted with GPS coordinates on Google Maps. The OBDLink MX's speed allows me to get extremely impressive temporal resolution logging on over 15 different PIDs.
The OBDLink MX is a great piece of engineering, and ScanTool.net's service is excellent. I look forward to racing my car in the future and being able to go back and look at the nitty gritty details of what was going on with my car and where.

This Bluetooth adapter, though a little expensive, works very well. It includes good instructions and a simple scan tool program. You can use with an android device such as a phone or tablet by installing an app. I use torque and It works very well. I really haven't had the time to try any of the other apps. The data stream from the adapter is very quick. Not quite real time like a professional scan tool, but very close. You can install the scan tool program that the tool comes with on a laptop with the included disc, or by downloading with the security key code. I have not yet had a chance to try the computer program with it. If you are a do-it-yourself-er you may be able to save a little money by using the OBD link to aid in diagnosing your vehicle. Just remember that it is not a substitute for a well trained and experienced diagnostic technician! Overall OBD link MX seems to be a very good and well built adapter. No problems whatsoever. Very compact and the firmware is upgradeable which is unusual for similar adapters. Although it is a little expensive compared to other adapters, I definitely recommend it.Satisfaction

This Bluetooth powered OBD-II interface adapter has got to be one of the coolest products out there right now. It may be small in stature but it becomes a giant when coupled to a capable software solution such as the Android app "Torque Pro". I have used this device on three different occasions so far allowing me to successfully troubleshoot and clear those pesky "Check Engine" lights that won't get you past an emissions test. I was really impressed with the speed in which it retrieves the vehicle information including any freeze frame data available. Moreover, this tool is widely adaptable to function with other operating systems as well (i.e. Windows, Symbian). There is only one small problem I have ran into with this device. After you have poked around inside your vehicle's secret, dark digital bowels, monitored its sensors, fixed the problems and came away with a feeling like "YEAH!", it is too easy to forget unplug it and take it with you as there is no cord. But don't worry it will even shut itself off to avoid draining the vehicle battery.Satisfaction
