Hi, we have an old M4 with software version 3.72 in the ECU but cannot run the correct software. The floppy disk that came with the M4 is defective. Loading other versions from the website gives the warning of incompatible software version. Upgrading fails because we do not have the SUU. The PCI cable is working just fine.
Can anyone supply me the 3.7/3.72 software?
Thanks in advance!!
