Diagnosing and resolving issues with your Harley-Davidson motorcycle can be a daunting task. However, with the right DIY scan tool, you can save time and money by troubleshooting problems yourself. This article will compare two popular options, Centurion Super Pro and Diag4Bike, to help you choose the best tool for your needs.
Centurion Super Pro: Pay-Per-Bike Diagnostics
The Centurion Super Pro, offered by Techno Research, utilizes a pay-per-bike licensing model. The initial investment is around $750, including the module, cables for various Harley connectors (pre-Rushmore, Rushmore, and newer), software, and a laptop connection cable (laptop not included). Each additional bike license costs approximately $75. While tuning capabilities are available for an extra fee, this review focuses on diagnostic functionality.
Annual software updates are necessary to access new features and compatibility with the latest models. While the current year’s updates are free, subsequent versions require an upgrade fee (estimated around $300). Skipping updates doesn’t render the software useless; it simply limits access to newer functionalities. However, catching up on missed updates involves a pro-rated fee.
One drawback of the Centurion Super Pro is its less-than-intuitive user manual. Navigating the software and understanding its functionalities may require some trial and error. However, Techno Research offers phone support for assistance. Their online manual can be found here: centurion-introduction (be warned, it can be slow to load). Sections 7 and 8 are particularly relevant for diagnostic procedures.
Diag4Bike: A More Straightforward Approach
Diag4Bike offers a different approach, providing comprehensive diagnostics without per-bike licensing. However, this comes at a higher initial cost of around $1200. Similar to Centurion Super Pro, tuning is available for an additional fee per bike. The hardware includes the module (with a Bluetooth option available), cables for different Harley connectors, and software.
Diag4Bike’s annual software update structure mirrors that of Centurion Super Pro, with free updates for the current year and a $300 fee for subsequent versions. The update fee increases to $400 for skipping one year and $450 for skipping two or more.
While Diag4Bike boasts a more user-friendly interface, its user manual leaves room for improvement. Support is available through HardDrive/VTwin Products, the distributor, who can relay questions to the developers in the Czech Republic. The online manual is available here: Diagnostics – DOC4BIKE. The “Toolbox” section contains most of the commonly used diagnostic functions.
Choosing the Right Tool: Centurion Super Pro vs. Diag4Bike
Both Centurion Super Pro and Diag4Bike are powerful DIY scan tools capable of diagnosing a wide range of Harley-Davidson issues. The best choice depends on your individual needs and budget. If you only work on a few bikes and prefer a lower initial investment, the Centurion Super Pro’s pay-per-bike model might be more suitable. However, if you work on multiple bikes or prioritize a more intuitive interface, Diag4Bike’s higher upfront cost could be a worthwhile investment. Consider your long-term usage and weigh the cost of per-bike licensing versus the higher initial price when making your decision. Regardless of your choice, investing in a DIY scan tool empowers you to take control of your Harley’s maintenance and repairs.
