Hi guys, i wrote several times tuned files on my mercedes w220 edc15c6 ecu.
Today, tried to put ecu on car, nothing, dead.
I put ecu again to FG Tech Galletto V54 , when i hit ecu ID it gives message 5vg and points, well no information.
Tried to write original file, nothing, error.
Tried with MPPS ,nothing.
All operations were made on bench.
What the hell just i did ? :)
