This almost sounds like a noob question, but I got the Mark D chip for the 91 325i with 19lb injectors. I went to go put it in today and my ecu cover reads 0 261 200 524 on the green sticker. I have never heard of that number before. I have two other white stcikers that have 173 on them as you can see in the pic. Basicly I'm asking if a chip I got for a 173 ecu will work in this.
My chip reads 173.7k0-9317
