OBDLink MX+ vs. LX: Why is MX+ more costly, but preferred by drivers? Review – Quick Verdict
After weeks of testing both the OBDLink MX+ and LX on multiple vehicles, including a modern Ford, an older GM truck, and a European import, the MX+ consistently proved why it commands a higher price and driver preference. The LX is an excellent, no-fuss adapter for reading and clearing check engine lights, viewing real-time sensor data, and performing emissions readiness monitors. It works flawlessly for these standard OBD2 functions. However, the MX+ operates on another level entirely. Its ability to connect to enhanced, manufacturer-specific networks (like GM LAN, Ford MS-CAN, and many others) provides a staggering amount of additional data. I could view live data from the transmission control module, run tests on the anti-lock brake system, and check battery voltage of individual modules—functions simply unavailable on the LX for most vehicles.
The preference among drivers, especially enthusiasts, DIY mechanics, and those with newer or more complex vehicles, leans heavily toward the MX+ because it future-proofs their investment and delivers a depth of information that feels professional. While the LX handles the basics with aplomb, the MX+ answers the “why” behind the code, not just the “what.” For anyone who wants to go beyond simple code reading and truly interact with their car’s various computer systems, the MX+ is the unequivocal choice.

OBDLink MX+ vs. LX: Why is MX+ more costly, but preferred by drivers? Overview
The OBDLink MX+ is a professional-grade, Bluetooth and Wi-Fi OBD2 scan tool designed to bridge the gap between basic code readers and expensive dealership diagnostic computers. Its primary purpose is to give you, the driver, access to the same depth of information a technician would see on their high-end scanner, but through your own smartphone or tablet. It reads all standard OBD2 protocols, but its defining characteristic is the robust support for manufacturer-specific enhanced diagnostics. This means it can communicate with modules beyond the engine computer, such as those controlling the transmission, airbags, ABS, and instrument cluster on a vast array of vehicle makes and models from 1996 to the present.
This product is designed for a specific type of user: the automotive enthusiast who isn’t satisfied with just clearing a check engine light. It’s for the DIYer who wants to diagnose an intermittent ABS warning, monitor transmission temperature while towing, or test window and sunroof functions. It’s also incredibly valuable for owners of newer, more complex vehicles, or specific brands like European imports, where basic scanners often fail to provide meaningful data. The MX+ is also a favorite among those who use their vehicle for performance tuning or data logging, thanks to its fast update rate and stable connection.
Key specifications that set it apart include its dual Bluetooth and Wi-Fi radios, a fast 32-bit processor for handling large data streams, and a sturdy, compact casing that can be left plugged in. It’s compatible with a huge ecosystem of apps, from the feature-rich OBDLink app (which is free and tailored for the device) to powerful third-party options. The build quality feels substantial, and the bright LED status lights provide clear connection feedback. In essence, the MX+ isn’t just a dongle; it’s a gateway to your vehicle’s complete electronic nervous system.

Key Features & Performance
Understanding why the MX+ is preferred requires a closer look at what it actually does. In my hands-on testing, these features made the difference between guessing and knowing what was happening with my vehicles.
Enhanced OEM Diagnostics & Module Access
This is the flagship feature and the core reason for the MX+’s higher cost and driver preference. While the LX reads generic OBD2 data (engine RPM, fuel trim, standard trouble codes), the MX+ can access proprietary vehicle networks. On a 2010 Ford F-150 I tested, the LX showed me engine data. The MX+, however, allowed me to connect to the Body Control Module (BCM) to check for door-ajar switch codes, the Instrument Panel Cluster (IPC) to run gauge tests, and the Restraints Control Module (RCM) to check for airbag history. This level of access is transformative. For a modern vehicle with dozens of computers, this feature turns your phone into a powerful diagnostic station, letting you pinpoint issues in specific systems without a trip to the shop.
Dual Bluetooth & Wi-Fi Connectivity
The flexibility here is a significant performance advantage. The LX is Bluetooth-only, which is perfect for use with Android phones and tablets. The MX+, however, adds a dedicated Wi-Fi radio. I found this invaluable for two reasons. First, it allows seamless connection to iOS devices (iPhone, iPad), which typically work better with Wi-Fi OBD2 adapters. Second, it allows you to use apps that require specific connection types. For instance, some advanced tuning or logging software prefers a Wi-Fi connection for its higher data throughput and stability. Being able to choose the right connection for the device and task at hand makes the MX+ a more versatile tool in your kit.
Superior Data Logging and App Ecosystem
Performance isn’t just about what data you can get, but how reliably and quickly you can get it. The MX+ uses a more powerful internal processor than the LX. In practice, this meant smoother real-time data graphing and the ability to log dozens of parameters simultaneously without dropping frames or disconnecting. I logged a 30-minute drive while monitoring engine load, fuel pressure, short- and long-term fuel trims, and transmission fluid temperature with zero hiccups. Furthermore, the MX+ is officially compatible with a wider range of third-party apps. While the LX works with many, the MX+ is certified and optimized for powerhouses like Torque Pro (Android) and Car Scanner (iOS/Android), giving you immense control over how you view and interact with the data.
Professional-Grade Build and Reliability
From a usability standpoint, the MX+ feels like a tool built to last. Its casing is robust, and it gets noticeably less hot during extended use compared to many cheaper adapters. The status LED is multi-color and clearly indicates power, connection, and network activity. Most importantly, the connection stability is exceptional. I’ve used other adapters that would randomly disconnect, corrupting data logs. The MX+ maintained a rock-solid connection even during long, bumpy drives. This reliability is critical when you’re depending on the data to diagnose a tricky intermittent fault. It inspires confidence, which is a key part of why experienced users prefer it.
