I am an E30 guy too, as that what got me into BMW's. 96 was the first year BMW introduced the security features of the EWS2 that is built into the DME. You have to have the proper encoded chip on the key and EWS2 unit all aligned with the DME in order for the car to start and run. You can't just throw in a different computer and expect the car to work. You can have the computer realigned at the dealer but it is a PITA and costs money. You know what a dealer can charge just to look at your car! It is easier and cheaper to just buy everything you need to make the car run which is almost impossible at a JY because they seldom have the key and BMW won't make you a new key unless you show title and registration. I have kept all this stuff together for just this very reason. |
