The price of a genuine VCDS cable can be prohibitive for hobbyists or those on a budget. This article explores two VCDS clone options, comparing their price, functionality, and potential drawbacks. We’ll delve into the technical details of each cable, including the chips used and potential security concerns.
Decoding the Differences: Atmega162 vs. STM32F405
Two distinct VCDS clone cables were tested: one based on the Atmega162 chip ($29) and another utilizing the STM32F405 chip ($49). The price difference reflects significant variations in performance and compatibility.
The Atmega162 Cable: A Budget-Friendly HEX-CAN Solution
The Atmega162 cable presented several challenges. First, it required a separate loader program flagged as malicious by antivirus software. This raises security concerns, potentially exposing your system to risks. Furthermore, this cable is functionally equivalent to an older HEX-CAN cable, offering no advantages over a genuine HEX-CAN interface.
While the Atmega162 is used in genuine Ross-Tech HEX-CAN cables, this clone version doesn’t offer the functionality of a genuine VCDS. Using this cable with its potentially harmful loader is risky and not recommended. A virtual machine environment might mitigate some risks but adds complexity.
The STM32F405 Cable: A Viable Alternative?
The STM32F405-based cable offered a more promising experience. Priced at $49, it functioned without requiring a separate loader and performed noticeably faster than the HEX-CAN cable, boasting higher logging sample rates and quicker communication with the vehicle.
Further investigation revealed this cable uses a locked STM32F405 chip, requiring specialized hardware like a ChipWhisperer to bypass security measures. This suggests potential licensing issues and raises questions about long-term compatibility with future VCDS software updates.
Conclusion: Balancing Cost and Risk
Vcds Clone Prices vary depending on the chip and functionality. The Atmega162-based option is cheaper but essentially a HEX-CAN cable with a potentially dangerous loader. The STM32F405 version, while more expensive, performs better but might have compatibility limitations in the future. While these clones offer a lower entry point, investing in a genuine VCDS ensures full functionality, software updates, and avoids potential security risks.
