3.2 Online and Offline Operation
The programming software can be used in two ways: “Online” and “Offline”. In the Online
mode, all the changes made to the maps and set-up data in the software will be transmitted to
the ECU. This is what is called online programming and it is in this mode that most tuning is
carried out. In the offline mode, making changes to the maps and set-up data will not affect
the ECU since communication between the programming PC and the ECU is not active.
Working in the offline mode is a convenient way of checking maps that have been stored to
disk and reviewing Data-logs that were taken when in the Online mode.
It is advised that first time users familiarise themselves with the software in the “Offline”
mode before “Online” operation is attempted. Most features of the software are available in
the “Offline” mode so that the user can learn the controls for navigating the software. The
only features not available “Offline” are: The Engine Data Page and the Calibrate Throttle
function, these features require communications with the ECU.
The Software can be identified as “Online” or “Offline” by the label in the middle status bar
that indicates whether the software is on or offline. The other indicator is the Go –
Offline/Online button. When offline the button displays Go – Online. When online the button
displays Go offline.
NOTE:
For changes made in software to be transmitted to the ECU the programming
software should be online.

(supplied with most kits) connected to the ECU loom and the programming PC.
