5. Open the Runtime View (F12 or 'R') and select the 'General' tab.
6. Compare the MAP and BAP values and ensure they have a similar reading (within 1 kPa).
7. Perform a 'Store' by pressing F4.

TPS Calibration
E-Throttle Vehicles:
The Throttle Position Sensors (TPS Main and Sub) and Accelerator Position Sensors (APS Man and Sub) are
used by the ECU to control the throttle blade position and to calculate various engine management
parameters used by functions such as idle speed control,acceleration enrichment and motor sport features. It
is very important that these inputs are setup correctly and the E-Throttle operation is tuned properly before
starting or driving the vehicle, failure to do so can result in damage to the Throttle body, engine, vehicle and
even the operator and bystanders. The following procedure shows how to calibrate the APS and TPS sensors:
1. Connect a laptop/notebook PC to the ECU and connect to the ECU using PCLink.
2. Open Electronic Throttle -> Accelerator Position Sensor and ensure that the APS (Main) Source and APS
(Sub) Source settings are set to the correct inputs. Refer to the Pinouts section of this manual for details.
3. In the same window double-click on 'APS Calibration' and follow the instructions on the screen.
4. Open Electronic Throttle -> E-Throttle 1 -> Throttle Position Sensor and ensure that the TPS (Main)
Source and TPS (Sub) Source settings are set to the correct inputs. Refer to the Pinouts section of this
manual for details.
5. In the same window double-click on 'TPS Calibration' and follow the instructions on the screen.
6. If your vehicle has two E-Throttles then repeat the above two steps for TPS 2(Main) and TPS 2 (Sub) in E-
Throttle 2.
7. Select the 'General' tab in the Runtime Values window (F12 or 'R').
8. Ensure the APS (Main) and APS (Sub) values read 0% when the pedal is released and 100% when fully
depressed.
9. Perform a 'Store' by pressing F4.
1.7.5
IAT Sensor Selection
This section only applies when an Intake Air Temperature (IAT) sensor has been wired and fitted to the intake
system. It is important that the ECU is calibrated to match the sensor installed in the engine. This procedure
is as simple as selecting the correct sensor type as follows:
1. Connect a laptop/notebook PC to the ECU and connect to the ECU using PCLink.
2. Click on 'Analog Channel' in the configuration tree.
3. Select the An Temp channel the sensor has been wired to.
4. Ensure that channel (and only that channel) is set to 'Inlet Air Temperature'.
5. Select the correct 'Temp Sensor Type'.
6. Select the 'Analog Inputs' tab in the runtime values section of PCLink (lower part of the screen).
7. Ensure that IAT reads the correct temperature.
8. Perform a 'Store' by pressing F4.
1.7.6
Input and Output Setup
As the Link G4X & G5 Plug-In ECUs are often designed to run several models there are a few items that must
be set-up to make the ECU specific to your model.
The Pinouts section of this manual gives a list of the functions of each channel based on the target vehicle.
It is the tuners responsibility to make sure that the following channels are set-up correctly for the vehicle
model the ECU is fitted to:
All Auxiliary Output Channels
Use the 'Test On' or 'Test PWM' (at 10 Hz) functions to test the wiring of channels.
All Digital Inputs
Look at the Digital tab in the Runtime Values window (F12 or 'R') to confirm each channels operation.
All Analog Volt and Temperature Inputs
Look at the Analog tab in the Runtime Values window (F12 or 'R') to confirm each channels operation.
