In this support section you'll find Link ECU software, firmware upgrades and other quick reference guides.

For help setting up your ECU and accessories (such as sensor calibrations) use the PC Link HELP file. This contains all the information needed. The HELP file is found in our free software download: PC Link

Your Link ECU Dealer

Link does not sell direct to the public. For Unlock Codes, Warranty or Servicing enquiries, you will need to contact the Link ECU Dealer you purchased the Link ECU from. All Link ECU’s are delivered ‘locked’, which is an anti-theft measure, and Link ECU’s can only be unlocked by your dealer.

Help with your ECU

If you are after more information or help with your Link ECU, we recommend you follow these steps

  1. As a proud Link ECU Owner, your first port of call is the Owner’s Manual.  This comes in the box along with the ECU when purchased, but can also be downloaded in the links above.
  2. Link’s tuning software, PC Link, has a Help file which can be found by pressing F1.  This Help File lists all features within PC Link, categorically indexed to make things easy for you to find.
  3. The Link ECU Forums and YouTube channel (also above) contain plenty of information. Use the search bar to find the information you are after.
  4. Finally, we have Tech Support available for Dealer’s questions. Please refrain from contacting Tech Support until you have made use of the resources above first.
