Use ME9.7 data to generate EIS W164(2009-) 

1 Read ECU to generate EIS file .
2 Then we erase the used EIS (or get new EIS ).
3 Load ECU data in CGDI MB (Need add original car SSID,VIN and set a password ) .
4 We write data to EIS with SSID and password
5 We add a key to activate the EIS
6 We Change the VIN
7 Some ELV have password ,need to erase the ELV too
Tip:
1 Wrong SSID may cause EIS can not calculate the password
2 Change VIN and SSID together may cause EIS can not activate
