MSD81 Upgrade

One of the most common failures of N54 powered BMWs is MSD80 (DME aka ECU). Usually MOSFETs inside the DME fail on load.

This is when you should upgrade your MSD80 to MSD81. You only need to send us your DME module or CAS module with one of your key fobs.

You can also send us your injectors flowing rate numbers and we can code them in before sending your items back to you.

3/4 Days to be completed then we will ship with 2 day shipping for free.

 YES! You send us your DME or CAS + KEY then we return them back to you SAME DAY!

 YOU NEED TO SEND US YOUR CAS AND A WORKING KEY IF YOU ARE PURCHASING KEY(S).  IF YOU DON’T HAVE A WORKING KEY, WE WILL NEED YOUR CAS MODULE AND DME.
