a. Select the desired ‘MAP Limit Mode’
b. Enter the required MAP limiting value for each
engine temperature in the ‘MAP Limit Table’.
3. Click on ‘Vehicle Speed Limit’
a. Set the ‘Vehicle Speed Limit’ to a high enough
value to ensure it is not invoked during tuning.
Note that this limit will only be effective if a
vehicle speed sensor is correctly wired and
configured.
4. Perform a Store to permanently save changes to
the ECU by pressing F4.
Auxiliary Output Set-up
This section configures the ECU’s Auxiliary Output drivers for the devices they have been
wired to. Preparing a configuration table as shown in Section 2.7 of this manual will greatly
simplify set-up of Auxiliary Outputs. Note that one auxiliary channel should always be wired
and configured for the fuel pump relay drive.
1. Click on ‘Auxiliary Outputs’ then select the first
Auxiliary Output that requires configuration:
a. Select the required ‘Function’ for the Auxiliary
Output channel.
b. Configure the channel as required. Refer to
PCLink Tuning Software’s online help for more
information on adjustments.
2. Configure each additional Auxiliary Output
channel. Ensure unused channels have their
‘Function’ set to ‘Not Selected’. Note that the ‘Test
On’ and 'Test PWM' functions can be used to test
wiring of auxiliary output devices.
3. Configure any Ignition and Injection channels used
for auxiliary output functions in the same manner.
4. Perform a Store to permanently save changes to
the ECU by pressing F4.
Digital Input Set-up
This section configures the ECU's Digital Input channels for the devices they have been
wired to. Preparing a configuration table as shown in Section 2.7 will greatly simplify set-up
of Digital Inputs.
