Final Recommendation
The Autel XP400 Pro is generally the better choice for most users due to its versatility, standalone functionality, and slightly lower price. It excels in chip programming and immobilizer tasks, making it ideal for locksmiths and general diagnostic shops. However, if your focus is ECU/TCU cloning, the Launch X-Prog3 is the superior tool, especially when paired with a Launch tablet.
If you’re starting fresh and don’t own either brand’s tablet, consider your primary vehicle types and whether you need standalone capabilities. For a balanced approach, the Autel XP400 Pro paired with an IM508 or IM608 offers excellent value and flexibility.
X-Prog3 has more ECU functions and you can add an
adaptor and run it via PC.
XP400Pro can do more IMMO functions and if you can
still find it online there is the Auro PC Utility for it as well.
