Thread: Blue MAP Sensor Vacuum Line

  1. #1

    Default Blue MAP Sensor Vacuum Line

    Is the Blue MAP Sensor Vacuum line on the Terminator X only used if you don't use the connector on the harness to plug into a MAP Sensor on an LS3 Engine? If it's not used, do I plug it or leave it as is?

    Holley EFI systems work with 1 to 5 Bar MAP sensors. Make sure to select the proper sensor used in the handheld or software.
    NOTE: Terminator X and X Max ECU’s have an internal 1 bar MAP sensor. For naturally aspirated & nitrous engines, you can connect the 1 bar MAP sensor located on the ECU to an available intake manifold port by using the appropriately sized quick-turn adapter. Other MAP sensors can be used by plugging the MAP sensor connector into the sensor or using an adapter harness.
