Choosing between the VXDIAG VCX SE and Scanmatik 3 (SM3) requires understanding their main features, differences, and use cases. Below is a detailed comparison to help you make an informed decision.
Compatibility
Both devices support:
- VXDIAG VCX SE and SM3 are J2534 PassThru adapters, compatible with diagnostic software like Benz Xentry and BMW ISTA.
- Both support PCMFlash and BitBox tools for ECU reading and writing.
Key Differences:
- VXDIAG VCX SE: Fully supports Vediamo and DTS Monaco engineering software.
- SM3: Only supports DTS Monaco, with limited functionality.
Features
VXDIAG VCX SE:
- Supports DoIP protocol but does not support CAN FD. (For CAN FD, the VXDIAG VCX FD model is recommended and is more affordable.)
- Compatible with a broader range of diagnostic and programming tools, making it ideal for users working across multiple brands.
- Faster and more stable communication when using the K-line protocol, allowing seamless operation of tools like Diagbox after license activation.
Scanmatik 3:
- Compared to the Scanmatik 2 Pro, it has upgraded CAN FD and DoIP protocols, added WiFi (replacing Bluetooth), and improved USB data transfer speed from 12 Mbps to 480 Mbps.
- The basic package now includes an auxiliary cable for added convenience.
Performance Issues
VXDIAG VCX SE:
- Performs reliably with tools like Diagbox, Vediamo, and DAS, making it a stable choice for diagnostic and programming tasks.
- No significant issues with K-line communication or ECU flashing.
Scanmatik 3:
- Faces issues with K-line communication, such as connecting to PSA Diagbox or flashing ECUs like Med9 and EDC16.
- Slower connection times and limitations with Vediamo coding and DAS operations.
Pricing
VXDIAG VCX SE:
- Offers better value for money, making it ideal for budget-conscious users.
- If CAN FD is required, the VXDIAG VCX FD model is also more affordable than SM3.
Scanmatik 3:
- Significantly more expensive, costing approximately twice as much as VXDIAG VCX SE.
Recommendation
VXDIAG VCX SE:
- Best suited for users working across multiple brands, compatible with tools like Vediamo and DTS Monaco. It’s more affordable, feature-rich, and offers stable performance.
- Ideal for those needing reliable K-line communication and programming functionality.
Scanmatik 3:
- Suitable for users who specifically require CAN FD and DoIP and have a higher budget. However, if you already own a Scanmatik 2 Pro, upgrading to SM3 may not be worthwhile since SM2 Pro continues to receive updates and new features.
Conclusion
If you’re looking for a cost-effective, versatile diagnostic tool that supports multiple brands and works seamlessly with engineering software like Vediamo and DTS Monaco, the VXDIAG VCX SE is the better choice. However, if CAN FD is essential and budget is not a concern, the Scanmatik 3 could be an option, despite its limitations in certain functionalities.
