The G4X EVOLink (IV-VIII) Plug-In ECU supports several options for fitting of a MAP sensor. Any one of the following options can be used:

1. The G4X EVOLink (IV-VIII) Plug-In ECU has an internal in MAP sensor. This sensor is either rated to 4.0 Bar absolute pressure (3.0 bar boost) or 7.0 Bar absolute pressure (6.0 bar boost) depending on the age of the bottom board. Which sensor is fitted can be ascertained by looking at the sticker on the bottom board (should say 7 Bar for 7 Bar models and nothing for 4 Bar) or by looking at the MAP value when at atmospheric pressure and changing the calibration setting. Connect this hose to Manifold Pressure. The internal MAP sensor is connected to AN Volt 1.

2. The factory MAP sensor - Some models are fitted with a factory MAP sensor, this is wired to An Volt 8. The correct calibration will need to be determined due to variations in sensors across different models.

3. MAP Through AFM – The factory AFM wiring can be used to install a MAP sensor.

·Pin 1 is connected to +5V

·Pin 3 is connected to AnVolt 2

·Pin 4 is connected to +14V

·Pin 5 is connected to Signal Ground

·Pin 6 is connected to An Temp 2 (Connect IAT sensor here)

 

4. MAP Through Expansion Connector - The expansion connector provides power, ground, and analog channels for the connection of a MAP sensor.

 

Make sure that the correct MAP sensor input has been selected in PCLink and a MAP calibration has been performed before attempting to start the vehicle.
