OK, the diagnostic connector is one way to get the information.

The other is the key and stomp.

hey i like that idea, how would you go about doing that on a 91 318is? im guessing buying hte diagnostic cable and hooking it up to a usb port some how, maybe it comes with one and then you'd need decoding software, and if you had all that im guessing you could change stuff right? im not much for computers, more the mechanical side of things, thats what i try to stay away from newer cars... howevr i couldn't resist the E30
