hey guys, i have posted this a couple of times but no answer. I bought a shark injector from turner motorsports, and tried to install it. It gave me a code 147 which means my car may have old new, or unknown data in the computer. I called turner and they said i needed to take it to the bmw dealership and have my cars computer updated, so i took it, and they did not know what i was tlaking about updating my onboard compute. IS there something else to do to my car that the dealership can do to update the msot recent settings? PLease help!
