If you’ve been relying on older Autel scanners like the MX808S, MK808Z, or MK808S, you’ve likely noticed their growing limitations with modern vehicles—they lack support for critical communication protocols like DoIP and CAN FD, have slower processing speeds, and miss out on time-saving features like Pre & Post Scan and Wi-Fi printing. For 2026, Autel has launched the advanced 900 series of wired diagnostic scanners to address these gaps, delivering upgraded hardware and expanded functionality at competitive price points. Today, we’re comparing two of the most popular models in this lineup: the budget-friendly MaxiCheck MX900 and the feature-rich MaxiPro MP900, to help you pick the perfect tool for your workshop or personal use.
