When you add a chip you can do it yourself, it depends though. Usually it is a replacement ECU which all you need to do is remove the old one and plug the wires into the new one.Originally posted by jennsydandrew@Jan 29 2004, 09:40 PM
I have a question. Do you have to do anything speacial to the beemer when you buy a chip? Can I install it myself? Why does a chip help HP?
I'm sorry but can somebody enlighten me with this? - how can I reprogam the ECU? will i have to hook it up to my computer? will i need some kind of a particular interface and software? thanks.. :screwyAs stated above a chip wont work in your car, you can just reprogram the factory ECU with a SI. CAI and exhuast will make some more power, and changing the pullies will free up some more.
