Hell to all I'm new to this tuning and I'm completely clueless as to what I'm doing. I have a e38 and a t42 for my LY6/4l80e swap. I have no clue what donor vehicle these came out of but I'm wondering if they have to be from the same vehicle or same year of engine and Tranny in order to work properly. I'd hate to purchase the tuner and run into rookie problems. Can anyone give me some insight so I don't waste my money please?
