The MEV17.2.1 ECU is known for internal power, MOSFET, and processor failures, which can lead to injector or ignition faults, no communication, or crank-no-start conditions.
We supply an ecu, fully programmed and cloned from your original — completely plug-and-play and ready to install.

How It Works

  1. Send us your original ECU, CAS, and key.

  2. We’ll program a replacement ECU to match your original unit — typically same or next business day.

  3. Your replacement ECU, CAS, and key are then dispatched back to you immediately, plug-and-play ready.

Optional Add-Ons

You can select additional services at checkout, such as:

  • Extra key / remote programmed (Blank manual blade will be included as well, not cut)
