GTTLink

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

1.Factory MAP Sensor – The RB25DET factory MAP sensor is suitable for use. It must be re-plumbed to a pressure source that measures vacuum and boost pressure*. The factory MAP sensor is wired to An Volt 3. The factory sensor is good for 125kPa (18psi) of boost. Ensure that the MAP Calibration is set to 'Nissan R34' in PCLink.

2.MAP Sensor Wired Through AFM – To avoid running additional wires into the engine bay, a MAP signal can be brought in through the AFM signal wires. The AFM is wired to An Volt 1. Refer to factory wiring manuals for AFM wiring connections. Make sure the AFM can not be reconnected.

3.MAP Via 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.
