The Launch X431 ACE sits at the borderline between DIY and professional garage use. Its large screen provides an excellent user experience, making it a versatile tool for all garage needs. With extensive vehicle coverage and ECU coding capabilities, it’s well-suited for tackling complex repairs.

The battery life exceeds expectations, and the pricing remains highly competitive, offering great value for passenger cars, both old and new.

However, the X431 ACE falls short when it comes to Heavy Duty Trucks. The additional cost of the SmartLink HD and the necessary software makes it less competitive compared to units specifically designed for truck diagnostics.
