Key item features

  • Engine Compatibility: Designed for GM LS 4.8/5.3/6.0 LS Truck Engines and LS2/LS3 with 58x Crank, 4x Cam, 4L60E/4L80E transmissions, Drive-by-wire throttle body control, and EV1 Injectors.
  • Tuning Capabilities: Features real-time fuel map learn, eliminating guesswork from base fuel table tuning, and includes a calibration wizard for quick base tune creation.
  • Injector Support: High impedance injector drivers safely power most stock LS and Holley EFI injectors, with an included support chart (does not control low impedance injectors).
  • Sensor Integration: Utilizes a Bosch LSU 4.9 wideband for accurate AFR readings and precise tuning, and includes an on-board 1bar MAP sensor with vacuum hose adapters.
  • 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.
