      this is something of a saga, I am in contact with Lee, to bring the matter to a close, at this moment the car has yet to start

      525I ECU

      The ecu worked well the 2nd time around. There was some confusion on the first ecu received. We have an Autologic and thought we were getting an unlocked ecu. That was not the case,it was programmed to the car and when we tried to program it we locked it up.
      Another ecu was sent and we did not try to program it and it worked flawlessly.
      Bottom line is we did not understand that RPM Motorsport was sending a preprogrammed ecu and out salesman didn't ask if we could program one.
      They did take care of it so we will definitely use them again. Mike

      Hello Christopher,

      First of all I would like to thank you for your honest review, it seems that there was a confusion from both sides. An Unlocked ECU is a Plug and Play unit which does not require any kind of programming, however, if programmed it will lock up due to the EWS system. The 2nd unit received was exactly how the factory programs their ECU.

      I have talked to the sales team and explained to be more clear in the future to help all our customers, hope you will always rely on us on your next order.

      Thanks

      Seth
