Terminator X Max gives GM LS1/LS6 engines complete fuel and spark control at a budget-friendly price, without the hassles of a cumbersome junkyard ECU tuning interface. Real-time fuel learn, high-impedance injector drivers, an onboard wideband oxygen sensor, and a full base-map library get the engine running quickly, while the 3.5-inch touchscreen handheld makes calibration approachable for first-time EFI builders.
Key Features:
- Built for GM LS1/LS6 engines with 24x crank reluctor, Drive-By-Wire throttle body, and EV6 injectors
- Real-time fuel map learning removes guesswork from base fuel tuning
- High-impedance injector drivers safely run most stock LS and Holley EFI injectors
- Onboard Bosch LSU 4.9 wideband for accurate AFR reading
- Integrated 1-bar MAP sensor, ideal for N/A or nitrous combos (2+ bar needs GM 12592525 and adapter 558-416)
- Includes MAP sensor vacuum hose adapters (1/8"-1/4" and 3/16")
- 4 programmable inputs (12V, ground, 5V, frequency) for sensors or activation triggers
- 4 programmable outputs (ground, PWM-) for fans, boost control, nitrous, IAC, and more
- Boost control vs. time, gear, RPM, or speed, with boost safeties
- Nitrous control: single channel, wet or dry, progressive or non-progressive, with rich/lean safeties
- Advanced custom tables (1D and 2D, including per-gear) for flex fuel offsets or custom safety tables
- Onboard diagnostic LEDs for ECU power, engine run, wideband status, TPS calibration, crank/cam signal
- 3.5" touchscreen handheld with calibration wizard, data-logging, and customizable gauge display
- Plug-and-play compatible with Holley EFI gauges, shift lights, digital/pro dashes
- Free EFI tuning software for full laptop control
