    Fixed what others could not.

    Ordered a cloned ecm from a different source. Installed it and did the same thing. The other company told me it couldn't be the ecm because it was setting the same codes. Sent the original ecm to RPM motorsports and in less then 1 weeks time including shipping both ways from USA to Canada and back I had a perfectly running bmw. I highly recommend RPM Motorsports. Thank you RPM for the excellent service
