Choosing the right OBD2 adapter can be crucial for diagnosing car issues, monitoring performance, and accessing real-time vehicle data. OBDLink offers a range of high-quality adapters, and two of their popular models are the OBDLink LX and MX+. If you’re trying to decide between these two, this guide will provide a detailed comparison to help you determine which adapter best fits your needs.
Before diving into the comparison, it’s essential to ensure your vehicle is OBD-II compliant. You can quickly verify this information by checking out Is my vehicle supported?. Once confirmed, let’s explore the key differences between the OBDLink LX and MX+.
OBDLink LX vs MX+: Unpacking the Key Differences
Both OBDLink LX and MX+ are designed to provide reliable OBD-II diagnostics, but they cater to slightly different user requirements. Let’s break down the features to highlight where they diverge.
OBD-II Protocol Support: Ensuring Compatibility
Both the OBDLink LX and MX+ offer broad protocol support, ensuring compatibility with a wide range of vehicles. They both support the essential OBD-II protocols: ISO 15765-4 (CAN), ISO 14230-4 (KWP2000), ISO 9141-2, and J1850 VPW (GM). However, the OBDLink MX+ takes the lead by also supporting J1850 PWM (Ford) and advanced protocols like MS-CAN (Ford) and SW-CAN (GM).
For most users with standard OBD-II vehicles, the LX provides sufficient protocol coverage. However, if you drive a Ford or GM vehicle and require access to manufacturer-specific networks like MS-CAN or SW-CAN for advanced diagnostics or features, the MX+ is the superior choice.
| Feature | OBDLink MX+ | OBDLink LX |
|---|---|---|
| ISO 15765-4 | ✔ | ✔ |
| ISO 14230-4 | ✔ | ✔ |
| ISO 9141-2 | ✔ | ✔ |
| J1850 PWM (Ford) | ✔ | ✔ |
| J1850 VPW (GM) | ✔ | ✔ |
| MS-CAN (Ford) | ✔ | |
| SW-CAN (GM) | ✔ |
Connection Type: Bluetooth Convenience
Both the OBDLink LX and MX+ offer Bluetooth connectivity for wireless communication with your devices. The OBDLink LX utilizes Bluetooth v3.0, providing a reliable wireless connection. The OBDLink MX+ steps up with Bluetooth v3.0 and Bluetooth v5.0 Low Energy (BLE), offering enhanced compatibility and potentially faster data transfer speeds, especially with newer devices.
If Bluetooth connectivity is a priority, both adapters deliver. The MX+ offers a slightly more future-proof Bluetooth specification with BLE support, which can be beneficial for users with the latest smartphones and tablets.
| Feature | OBDLink MX+ | OBDLink LX |
|---|---|---|
| Bluetooth v3.0 | ✔ | ✔ |
| Bluetooth v5.0 LE (BLE) | ✔ |
Voltage Rating: Standard Automotive Systems
Both the OBDLink LX and MX+ are designed for standard 12V automotive systems, operating within an 8-18V range. However, the OBDLink MX+ distinguishes itself with 24V compatibility and tolerance. It can operate in 24V systems and is designed to safely shut down if exposed to 24V, offering broader compatibility for some truck and heavy-duty applications, although primarily still aimed at standard passenger vehicles. The LX is focused solely on 12V systems.
For typical car owners, the 12V rating of both adapters is perfectly sufficient. The MX+’s 24V compatibility is an advantage for users who might work with a wider range of vehicles, including some light-duty trucks or vehicles with 24V systems.
| Feature | OBDLink MX+ | OBDLink LX |
|---|---|---|
| 12V Automotive Systems (8-18V) | ✔ | ✔ |
| 24 Volt Compatible | ✔ | |
| 24 Volt Tolerant | ✔ |
Device Operating System: Wide Compatibility
Both the OBDLink LX and MX+ boast excellent compatibility with various operating systems. They both seamlessly work with Android, iOS (Apple), and Windows devices. This ensures you can use your preferred smartphone, tablet, or laptop for vehicle diagnostics regardless of whether you choose the LX or MX+.
OBDLink LX Bluetooth Adapter for Vehicle Diagnostics
Wireless Security: Protecting Your Connection
In terms of wireless security, both the OBDLink LX and MX+ prioritize secure communication. Both adapters feature 128-bit data encryption for their wireless connections, safeguarding your vehicle data from unauthorized access during wireless data transmission. This is an important feature, especially when using Bluetooth for OBD-II diagnostics, ensuring a safe and secure connection.
| Feature | OBDLink MX+ | OBDLink LX |
|---|---|---|
| Wireless connection: 128-bit encryption | ✔ | ✔ |
OBDLink MX+ Bluetooth and BLE Adapter for Advanced Diagnostics
Choosing Between OBDLink LX and MX+: Making the Right Decision
The choice between the OBDLink LX and MX+ depends on your specific needs and vehicle type.
Choose OBDLink LX if:
- You need a reliable Bluetooth OBD2 adapter for general car diagnostics.
- Your vehicle is a standard OBD-II compliant car, and you don’t require MS-CAN or SW-CAN access.
- 24V compatibility is not a concern.
- You are looking for a balance of features and value.
Choose OBDLink MX+ if:
- You want the most comprehensive OBD-II protocol support, including MS-CAN and SW-CAN, especially for Ford or GM vehicles requiring advanced diagnostics.
- You prefer the latest Bluetooth technology with BLE support for potentially faster and more efficient connections.
- 24V compatibility or tolerance is beneficial for your use case.
- You want the most feature-rich and versatile OBDLink Bluetooth adapter available.
In summary, both OBDLink LX and MX+ are excellent OBD2 adapters. The LX is a fantastic all-around choice for most users, offering robust Bluetooth connectivity and essential OBD-II protocol support. The MX+ steps up with broader protocol coverage, enhanced Bluetooth, and 24V compatibility, making it the top-tier choice for users needing advanced features and wider vehicle compatibility. Consider your specific vehicle, diagnostic needs, and desired features to make the best decision for your automotive needs.
