      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

      My BMW x5 just went nuts

      My BMW x5 just went nuts, hard start then no start at all. Scanning the car, they could not see the fault. I decided to Google, then I cam across rpm motorsport and it looked like the deal. I tried the online chat and met Chris. He was really nice, helpful and straight to the point. I Ordered and received a new ECU and EWS with new keys within 48 hours. Wow - impressive given that I am in west Africa. I simply cut one of the new keys, replaced the broken ECU and EWS and at the first crank, my x5 was up and running. KUDOS..,. keep this up and diversify the cars too. Service was excellent... Absolutely brilliant company.

      great service!

      Big thanks to Chris for his help in the replacement of the DME in my 2004 BMW 330CI. Due to an over zellous attempt to flash updated software onto my original DME which resulted in locking it up, making the car not start, I decided I needed to replace it with a new one. Chris assisted with the ordering and expediting so I'd have it the next day. Then he aligned it to the EWS in my car via remote controlling my PC connected to my car. Great to have my car running again. Thanks Chris for the great service!
