Has anyone had experience with Racing Dynamics chips. I have a 84 533i and this is one of the few that can fit my ECU. I've seen a lot of negative stuff about RD spamming members. Any suggestions would be appreciated. My Motronic part number is 261 200 008 Manuf 7/84. Gary -- to be removed from bmw, see /bin/digest-subs.cgi or email "unsubscribe bmw" to [email protected]
