VVDI Prog Programmer and Xhorse VVDI2 Key Programmer Comparison

VVDI2 is a comprehensive diagnose and programming tool (programming ECU and programming remote keys). VVDI Prog is like ecu programmer.For these two original Xhorse tools, will shware the comparsion about them.

1.VVDI Prog and VVDI2 Key Programmer Functions

VVDI2 is the update version for VVDI VAG Diagnostic, it inherited VVDI all features, mainly used to diagnose, programming ECU and keys and so on.

VVDI2 =VVDI options + BMW Multi Tool options + Porsche options + J2534(free)+ Tango(free) + Remote control generation(free)…..more other function will be added, the hardware and software can be updated by offical website (internet).

VVDI Prog programmer is famous Auto EEPROM MCU ECU programmer,VVDI PROG=(BMW ISN READ)+(EERPOM read)+(mcu read MOTO 9S12,5M48****)+PIN Code Calculation(more pin coder Algorithm ,than 40 type)

In short:

VVDI2 main function: vehicle diagnosis, odometer correction, ecu programming, remote key programming, key matching. e

VVDI PRO VVDIPROG v4.3.1 replace Porsche BCM 2M25J CPU

Managed to replace/ change Porsche 2M25J CPU on BCM, with back-up of original D-FLSH and P-FLSH

I first tried it myself.

Rewrite partition for 2M25J


If the D-FLSH is 16Kset EEE partition as 8


If the D-FLSH is 32Kset EEE partition as 0


Xhorse VVDI PROG Programmer:


Partition division complete. Then write the backup D-FLSH, and then P-FLSH

Finish encryption in the end. Porsche encryption byte: 7D



However, the BCM cannot work at all. Failed to read data and unencrypt.

Discussed with the engineer, i adopted the method below:

Step 1 - completely clear the encryption

Select the device and clear the encryption fully


Then CPU is all cleared. Again divide CPU partition. set the partition as 8

Step 2 - Write D-FLSH

Some data to modify before writing D-FLSH

Find out Line “7FF00” and replace “7D” with “FF”, then write CPU


Then perform encryption
