Hi folks, I have a 1993 E34 M5 (3.6L). When I bought the car, used, it had a Dinan chip on it and I am thinking of changing it back. Of course, I never had the original BMW chip nor did I get it from the original owner. I am looking for an original one (preferably, but not limited to, a 1993 one). Anyone has one to sell? Drop me a line and I will get in contact with you. Cheers!
