10 PC Tuning
G4 ECU's require PC/laptop tuning using the PCLink Tuning Software application running on
a Windows based computer. PCLink Tuning Software may be downloaded from www.
LinkECU.com. Note that when new versions of PCLink Tuning Software are released they
are posted on the website and may be downloaded at no cost. Also note that G4 ECU's
must be used with the correct version of PCLink Tuning Software.
The G4 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 will not
work with the G4 ECU and are difficult to uninstall.
10.1 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 Tuning Software installation as described in the
following section. Should internet download not be practical, a copy of the drivers on CD
can be obtained from your nearest Link Dealer.
10.2 Installing PCLink Tuning Software
Due to the frequent updates PCLink Tuning Software is no longer shipped with each ECU.
You will be required to download the latest version of PCLink Tuning Software from:
www.LinkECU.com
Should access to an Internet connection be impractical, the latest version of PCLink Tuning
Software can be requested from your nearest Link dealer on CD.
