This is a golden commercial opportunity to sell your remote tunes to thousands of Jetta, Taos, Golf, A3, Leon, or Formentor owners!
The Workflow: The MG1CS011 ECU has two different versions. Early versions with an SPC5777M MCU are simply OBD compatible. Plug in and go! Later TC298 MCU variants require an initial unlock. Here is the process:
- Mail-in Unlock: The ECU must first be sent to our facility for a highly secure unlock. You can order yours here.
- OBD on the One: Once returned, the ECU is ready! Your customer can now flash the solution directly from home via the OBD port with their One.
- The protocol has been specifically adapted for the SPC5777M variant.
- Application (ASW) blocks have been added to the readout.
- Crucial consequence: Older readouts are therefore no longer compatible with this protocol. Please ensure you take fresh readouts!
