The original ISN you posted is the same as the donor. Put these values in Tango's "Crypto Key" field and read the key again: 63 C5 1B 39 F2 AD

I can not read ISN from origional ECU, this one is for donor ECU, should the car start after i put those values in tango "crypto key" ??

No, the car won't start. Those values allow you to get more of the key data than just it's IDE. There is data stored in the key that I need to use to modify the CAS eeprom, so the car can be started.
