Hi all, Downloaded this today but not really sure if i should me messing around with the settings without knowing what i'm doing!!! http://www.unitronic-chipped.com/main/en/tuning/uni_setting.html has anyone found a guide or even better has anyone used this before. I'm having a guess you read the ecu first then save a copy of what it reads then do what you need to do then and write to ecu. at least then i'll have a back up of the current state. what will i gain from changing the settings? any power???
