Have Golf 7 edc17 to read and write the mod file, how to do with Ktag and Kess?
If you want write your mod file by ktag you must open ecu and connect it on table.
if you want write your mod file by kess obd, you must have vr file for your ecu, mod it and write by obd with kess.
Even you just read one of memories where the maps are and somebody modified that you can also write with kess.
Just pick your MOD file, then, open this on Kess (Maps place) and choose wirte.
If anything is wrong, the Ksuite will say to you before write (for exemple: wrong checkssum).
If you need vr protocol, google search or contact at @ Dolcevita (cartechnology.co.uk).
