LinkECU file types

PCLink saves a different file for each ECU generation. For all three we recover the password and remove the lock:

  • G4X

    .pclx

    Maps from G4X ECUs, saved by PCLink as .pclx files.

  • G4+

    .pclr

    Maps from G4+ ECUs, saved as .pclr files.

  • G4

    .pcl

    Older G4 ECUs, saved as .pcl files.

Why LinkECU maps get locked

PCLink lets a tuner put a password on a map so it can't be opened or changed without it. That protects the tuner's work, but it also locks the owner out when the tuner can't be reached, the car changes hands or the password is forgotten.

We recover the password from the file itself, so you get it back and the tune stays as it was. Nothing to ship and no factory reset — you just open your file in PCLink and type the password.

Proof before payment

See it worked before you pay

We unlock your file first and show you what we found in it. You decide whether to pay after that, and if we can't unlock it, you aren't charged.

Upload your fileRefund if your result doesn't work (tell us within 14 days).

  • Masked password

    We show the password we found in your file with every character but the first hidden. The full password appears as soon as you pay.
