On the software side, it not only supports basic diagnostic functions such as full system diagnostics and maintenance services, but also advanced features like bidirectional control, ECU coding and programming, and topology mapping. Furthermore, it is more affordable compared to the other two Autel scanners.
What is the Autel Maxisys Ultra
The Autel MaxiSys Ultra is a top-of-the-line full-system automotive diagnostic tool for 2025. As a high-end model, it features an octa-core processor, a 12.9-inch touchscreen, and an 18,000 mAh battery. It also includes a VCMI 5-in-1 device, supporting oscilloscopes, multimeters, and other functions.
In addition, it supports advanced functions such as topology mapping, ECU coding and programming, covering a wider range of vehicles and supporting diagnostics for modern models.
What is the Autel MaxiSys Ultra S2
The Autel Ultra S2 is Autel's latest scanner, launching in 2025, integrating AI and intelligent diagnostic technology. The Ultra S2 is the most expensive and advanced diagnostic tool among these three OBD2 scanners.
It features an octa-core processor, 512GB of storage, a large 13.7-inch screen, and the upgraded VCMI2, achieving a six-in-one design. In addition to the significant improvements in hardware configuration, the software functionality also features the first-ever integration of AI into an automotive diagnostic scanner.
It boasts an AI voice assistant and revolutionizes inspection methods through artificial intelligence technology—utilizing DVI technology. Furthermore, its topology mapping function and data-driven diagnostics and enhanced PID analysis are both highly powerful.

Autel Ultra Lite S Vs Ultra Vs Ultra S2: How to Choose?
Ultra Lite has the same top-level hardware as Ultra. The main difference is that Ultra Lite is equipped with MaxiFlash VCI while Ultra is equipped with VCMI for five integrated functions, including VCI, Oscilloscope, Waveform Generator, Multimeter, and OBD2 CAN BUS Tester. If you need oscilloscope functionality, the Ultra or Ultra S2 are good choices.
Obviously, Ultra Lite is more cost-effective than Ultra and Ultra S2. If its hardware configuration and software functions fully meet your needs, and you value cost-effectiveness, it would be a good choice.
If you want to experience higher-end features and hardware configurations, want to use AI functions, and have a sufficient budget, choosing the Ultra S2 will not disappoint you and will give you great value for your money.
