The LAUNCH XPROG3 with PC Adaptor can perform operations such as cloning vehicle ECUs. This is similar to the X431 ECU & TCU Programmer. So what are the differences between the two? This article will answer that question.
Answer:
The LAUNCH X431 ECU & TCU Programmer supports reading and writing vehicle ECUs, verification, and IMMO OFF functionality. It has its own PC software and is a fairly comprehensive ECU programming tool. However, it cannot be used with the X431 diagnostic tool, nor can it perform key programming tasks.
The LAUNCH XPROG3, when used with the X431 diagnostic tool, can perform key programming on various vehicles, as well as engine and transmission replacement. When the XPROG3 is used with the PC Adaptor, ECU programming software can be used for ECU cloning and programming.
Furthermore, the XPROG3 + PC Adaptor has the same functionality as the LAUNCH X431 ECU & TCU Programmer.
Both companies have the same policy and pricing for software updates: one year of free updates (after one year, it will be about €245 per year).
LAUNCH X431 ECU & TCU Programmer Renewal Card [1 Year]: €245 (Iteam. XNR-SS435)
LAUNCH XPROG3 + PC Adaptor Renewal Card [1 Year]: €245 (Iteam. XNR-SS436)
In conclusion:
If you simply want a tool to perform ECU cloning and programming, the LAUNCH X431 ECU & TCU Programmer is a good choice;
however, if you already own an X431 diagnostic tool or even an XPROG3 and want to work on ECUs, then purchasing the XPROG3 PC Adapter is a better option.
