Show original supplier description
This versatile device allows for independent control of up to 4 stages of nitrous, offering significant flexibility for optimizing power delivery. Programming can be done via a laptop using user-friendly graphical software or through an optional 3.5-inch color LCD touch-screen, which eliminates the need for a laptop during setup and allows for quick changes in the staging lanes. Key features include fully programmable stages, compatibility with Windows 2000, ME, XP, and Vista, and a NEW innovative NOSbus 2-wire network interface for seamless integration with other Holley/NOS supported products. The system supports detailed data-logging, enabling easy review of past runs via laptop, the handheld controller's SD card, or the LCD touch screen's SD card. Configuration files can be saved to accommodate different tracks or weather conditions. The Launcher offers advanced progressive ramp features, including RPM-based, time-based, MAP (boost) based, and nitrous percentage-based settings. Safety features are extensive, incorporating rich or lean cutoff based on A/F ratios, nitrous pressure cutoff, MAP pressure cutoff, and RPM cutoff. It also includes an integrated TPS for fuel-injected or drive-by-wire vehicles without a separate WOT switch and solenoid control channels with a 40-amp capacity for large solenoids. The controller requires appropriate Holley WBO2 sensors (p/n 534-198 or 534-194) and an extension harness (p/n 534-199) if using the lean/rich nitrous cutoff feature.
