To eliminate the confusion of tuning your base fuel table, this system features real-time fuel map learning technology. The high-impedance drivers are compatible with most factory LS injectors and Holley EFI injectors; furthermore, additional support is provided in the instruction booklet. Accurate readings and ultra-precise tuning control are a priority, which is why this system is equipped with the Bosch LSU 4.9 wideband O2 sensor. Whether your LS engine is a naturally aspirated or nitrous combo, the onboard 1bar MAP sensor will work perfectly and comes with vacuum hose adapters.

The included software suite lets you configure how much boost pressure is produced and customize the delivery rate of nitrous oxide. Several boost control operating modes, such as boost vs. time, gear, speed, RPM, and safeties are all readily available in the program. To enhance your engine’s power, multiple nitrous control channels are included: wet or dry, progressive or non-progressive, rich or lean safeties, and target closed-loop AFR. The software is loaded with various advanced tables that you can use to craft any custom table you desire.

12V, ground, 5V, and frequency inputs allow you to trick out this system further with additional pressure sensors, activation triggers, or a trans brake. Four outputs give you the opportunity to accessorize your system with fans, IAC kits, and much more. Monitoring your engine’s health is a priority, so this system has onboard diagnostic LEDs for ECU power, engine run, and many others. The handheld’s calibration wizard lets you easily construct a base tune and logs all your data for convenience. For additional customization, the ECU is designed to be small and compact so that you can mount it almost anywhere. If you already have some Holley EFI accessories, you can simply plug them into this system and get them started!
