Marc D M42 91 octane Chip
I have a 91 octane Marc D chip for M42 in my 318is.. I am selling it because I'm swapping to M52 so this chip is no longer needed. The Ecu is currently in my car at storage but it can retrieved easily. I believe it retails for 225$. I am selling for 150$ shipped. It has less than 500KM on it and it makes a massive difference in high RPMs.
