After a month of hands-on experience with the Autel Ultra scan tool, I’m ready to share my thoughts. Overall, I’m satisfied with this purchase and would recommend it to fellow automotive technicians. The scanning capabilities are consistent with Autel’s established performance, presenting a familiar interface and functionality seen in their previous models. Like any aftermarket scan tool, it has its strengths and areas for improvement. While Autel’s performance on Chrysler, Dodge, Jeep, and Ram vehicles has historically been less than perfect, it consistently excels with Honda and Nissan, which is a definite plus. The network topology feature is an interesting addition, although its practical utility in my daily workflow is still developing.
The integrated scope, particularly its wireless operation directly through the DLC, is a standout feature. While its immediate financial return is yet to be fully realized, I foresee significant potential. The CAN decoding function is functional, but its network compatibility is selective. It worked effectively on a 2015 Chevrolet Equinox but not on a 2013 Nissan Sentra, which isn’t a critical drawback.
For me, the wireless scope is the game-changing aspect of the Autel Ultra. Consider the example of diagnosing a Nissan Armada heater control valve:

This wireless capability allows me to control the HVAC system from the driver’s seat while simultaneously observing the scope readings in real-time. This eliminates the need for repeated captures due to incorrect settings and removes the reliance on a second technician to manipulate vehicle controls during testing. This hands-free operation extends to other diagnostic procedures like relative compression tests, in-cylinder analysis, and head gasket leak checks. For technicians working solo or when assistants are occupied, this wireless scope functionality offers substantial value. While it might not entirely replace a dedicated PicoScope, it comes remarkably close.
However, there are a couple of areas where the Autel Ultra kit could improve. The inclusion of low and high amp probes in the standard kit would be highly beneficial. While add-on kits are available, I would still lean towards Pico or AESWave for dedicated amp probes. Additionally, the included screen protector was of poor quality and was promptly replaced with an AESWave protector.
The MaxiFlash MVCI, mirroring the scanner itself, is notably large. Its size can be cumbersome, especially when space is limited during road tests. Nevertheless, it has performed flawlessly in flashing GM vehicles in my experience.
In conclusion, the Autel Ultra scan tool with scope is a worthwhile investment, primarily due to its innovative wireless scope feature. Despite minor shortcomings like the absence of amp probes in the base kit and the bulky MVCI, the advantages, particularly the wireless scope’s efficiency and convenience, make it a valuable tool for automotive diagnostics. I would certainly purchase it again, primarily for the enhanced workflow the wireless scope provides.
