-
Operating System: The ONE Pro runs Android 16.0, while the Lite, ONE, and ONE Plus run Android 12.0.
Function:
- Coding & Hidden Functions: The Lite supports coding only for major brands (Benz, BMW, VAG). The ONE adds support for Flash Hidden functions. The ONE Plus and ONE Pro expand coding coverage to include Porsche, Nissan, PSA, JLR, Ford, Volvo, and Toyota.
- Programming (ECU Flashing): The Lite and ONE offers no programming. The ONE supports flash hidden function for Benz, VAG and BMW. The ONE Plus supports limited programming (4 systems for BMW, Benz, VAG) and ONE Pro offer full-system programming for these three German brands.
- Advanced & Specialized Tools: The ONE Pro uniquely includes Graphical Diagnostics, DVI, Split Screen, an AI Voice Assistant, and an Oscilloscope. It also uses the upgraded ONE VCI Pro communication interface.
How to choose?
Your choice will largely depend on the level of advanced repair work you perform.
Choose the ONE Lite if: You are an entry-level user who needs solid all-system diagnostics, 52 service functions, and basic coding for German brands at the most affordable price.
Choose the ONE if: You need the Lite’s features plus the ability to perform Flash Hidden functions and basic (4-system) ECU programming for BMW, Benz, and VAG, all while keeping a lower entry cost.
Choose the ONE Plus if: You are a professional requiring extensive coding for 9+ brands, full-system programming for German makes, and IMMO (key coding) capabilities.
Choose the ONE Pro if: You want the absolute top-tier performance with maximum hardware specs (faster processor, more RAM/ROM, bigger screen), a charging dock, and advanced tools like a graphical oscilloscope and AI assistant for the ultimate diagnostic experience.
All four models share the same core strengths: 120+ vehicle makes coverage, all-system diagnostics, 52 hot functions, CAN-FD/DoIP/J2534 protocols, and support for gateway access (FCA, VAG, Renault, Nissan). All include 1 year of free updates.
