Hi guys I read somewhere that vag suit worked with edc15v golf 4 110cv , found the program I have to decided to try to turn the lounch control, and it was done, and a change in the torque limiters saved it all, I opened the map to the ecm to see the mod and I noticed that the checksum was already different then the checksum is automatically corrects by changing the other on the ecm? I need to use a program for the recalculation?
