Powering Up for the first time
Going Online with the Software
With your programming cable (RS232) attached to your ECU and the other end connected to your laptop,
power up the ECU by turning your key to IGN. Start the programming software on your PC. The following
window will appear on the screen when the software detects the ECU connected and able to communicate
with the software. If you do not get this window displayed, then check your ECU power and serial
connection. If you are using a USB/Serial adaptor ensure that the adaptor is emulating the same port that
you have selected for communications in the program setup tab of Halwin (default is COM1 in Halwin).

Figure 21 - Halwin loading map
After the map has been loaded into the ECU, the status indicator will show that the ECU is ‘ONLINE’.
When Online, all changes made to the maps will be sent to the ECU. When operating the software Online,
some caution is required as some changes are applied immediately in real time.

WARNING
Now is the time to double check that your ignition modules and fuel
injectors are not connected to the ECU. Powering up the ECU with the
wrong configuration can lead to damage to your ignition modules and/or
ignition coils or excessive fuel deposited in your engine if you leave these
devices connected.
