Review on 🔧 Autel MaxiPRO MP808K OBD2 Diagnostic Scanner: 2021 Newest Upgrade, Active Tests, Key Coding, Bi-Directional Control, OE Diagnostics, Oil Reset & More by Dustin Miller

A slower processor might not seem like a barrier to purchase, but even if you don't use it professionally, it's painfully slow. It took about 40 minutes to scan the 2003 suburb automatically. I can't imagine newer cars with even more modules. If you ever need to program or reprogram a module, most likely ECU coding is not what you need. J2534 is what you need to program the modules when you find a faulty module. This scan tool and the j2534 cost about $1,500, but you might want to ditch the option later if speed is ever important to you.
