Mack Ecu

[American]

I have a friend here in Germany, that had just bought a CX-613 Vision 2003, with E7 12 Ltr. motor., Cause of the Tire prices here, he needs to change the speed ratio in the ECU board computer, but the computer is always asking for a password to enter,

Where can he get it, ie., or what is the password ? , Mack Truck USA., would not give us the pass, without a Tax Number, which he does not have cause hes here in Germany

Tks, American

The password could be anything. The former customer must have had a password put in at a dealer. The truck dosen't come with a password from the factory. A Mack dealer can redownload the ECU and erase the password, usually takes less than an hour.
