Polaris RZR XP900

The G4X RZR XP900 Plug-In ECU supports several options for fitting of a MAP sensor. Any one of the following options can be used:

1.Internal MAP Sensor – To ease installation the G4X RZR XP900ECU is fitted with an internal 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. The internal MAP sensor is wired to An Volt 3.

2.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.
