When reading your remap with foxflash programmer via obd2 (i.e DCM6.2V) and this error pops out ERROR SEED-KEY what does it actually mean?
Its pretuned and seedkey changed so cant work via obd.
Well basically its saying that someones allready been on there. It prevents obd2 read/write, so only way is to bench or bdm your way in.
This is just another from of antituning protection used by tuners, companies as well as independent ones. It doesn’t actually prevent anything but on some cases makes things a little more demanding on tools.
Celtic tuning and many other commercial tuning providers use this form of protection.
