I am in the process of removing some unneeded equipment on my 2001 525i. Can I buy a computer from a tuner and just swap it with my factory computer? Who sells them? The main goal is just to keep my check engine light off and a tune just seems like a bright idea to me since I will be buying another computer anyway. I'm sure there are lots of tuners out there but since I just got into my e39, I have no idea who to deal with.
Shark injector from Turner? Won't do much.
