1.6 PC Tuning
Link ECUs require PC/laptop tuning using the PCLink Tuning Software application running on a Windows
based computer. PCLink may be downloaded from www.linkecu.com. Note that when new versions of PCLink
are released they are posted on the website and may be downloaded at no cost. Also note that ECUs must
be used with the correct version of PCLink.
The Link ECU has on board USB.
BEFORE connecting the ECU to your laptop, the USB drivers must be installed.
Failure to install the drivers on your laptop first may result in windows assigning
incorrect drivers. These drivers may not work with the Link ECU and are difficult to
uninstall. The correct USB drivers are installed as part of PCLink installation, as
described in the following section.
1.6.1
Installing USB Drivers
Before connecting the ECU to your laptop or PC, the ECU USB drivers must be installed. These drivers are
installed as part of PCLink installation as described in the following section.

Installing PCLink Tuning Software

USB drive, and then install on your laptop.
Installing from the web

2. Download the latest version of PCLink. When prompted to run or save the file, select save. It is
recommended to save this file on the desktop.
3. Double click the saved file and follow on screen instructions.

Communicating With Your ECU
After PCLink installation, you will be able to connect the Link ECU to the laptop to perform set-up and tuning
work.
1. Connect the ECU to your laptop using the appropriate ECU USB Cable. If not supplied with the ECU,
these can be purchased from a Link dealer. No other adapter or cabling is required. Connect the cable to
the connector labelled USB (typically has a red O-ring on the end of the cable).
2. Start PCLink by double clicking on the PCLink icon on the windows desktop.
3. Switch the key to the ON position. This will provide power to the ECU.
4. In PCLink, under the 'Options' menu, select 'Connection'. The connection options dialogue will open.
Selecting USB will give you the fastest connection, the 'Auto' connection port option will search for ECUs
on Wifi, USB and COM Ports before displaying a list of possible devices to connect to.
5. PCLink offers both mouse and keyboard control. To establish a connection between the PC and ECU
press the F3 key. The same process can be used to disconnect. If a successful connection is
established, PCLink will download settings from the ECU, otherwise you will be warned that an error has
occurred.
6. Make sure the connection shows “ONLINE” in the top right corner of PCLink.
7. To permanently STORE any changes made to the ECU press F4. If this is not done before turning the
ECUs power off all changes made will be lost.
