Key item features

  • Programmable I/O: Offers 4 inputs (12v, Ground, 5v, Frequency) for additional sensors or activation triggers, and 4 outputs (Ground, PWM-) for accessories like fans or boost control.
  • Advanced Controls: Provides comprehensive boost control (vs. Time, Gear, RPM, Speed) with safeties, and single-channel nitrous control (Wet/Dry, Progressive/Non-Progressive) with safeties.
  • Diagnostic & Display: On-board diagnostic LEDs indicate critical engine issues, and a 3.5" touchscreen handheld offers data-logging, customizable gauge display, and calibration wizard.
