8 STAGE NITROUS OXIDE CONTROL

Fully featured nitrous control eliminates the need for a separate nitrous controller device

Can be configured “Wet” or “Dry” with closed loop feedback

Progressive control based on time, RPM, or boost, requires part # 554-111

Lean or rich safety cutoff

Full timing retard/control configurability per stage based on RPM or time

INTEGRATED WATER/METHANOL INJECTION CONTROL

Uses Holley water/meth solenoids specially designed and calibrated for use with this EFI system to allow the user to enter water/meth flow as a percentage of fuel injector flow for water/meth tuning precision unmatched in the industry

Allows for two nozzles to be controlled

Nozzles available from 400 to 1000 cc/min

Complete control of pump activation, and low system safety features

TURBOCHARGER BOOST CONTROL

Fully featured boost control capability eliminates the need for a separate boost control device

Can be configured to control boost based on time, gear, speed, and manual inputs

Gear based boost control configurable by several different methods

“Boost Builder” functions offer the ability to assist building boost on the starting line by altering ignition timing, fueling, as well as nitrous oxide activation. Can also be used as an anti-lag function

INPUTS AND OUTPUTS

13 - “Multi-Inputs” – Can be configured as a 0-5V sensor input, 0-20v sensor input, thermistor temperature input, or high or low voltage input

30 - 0-5V Sensor Inputs – Configures any 0-5V sensor as well as some can be used as switched high or low inputs

4 - Speed Inputs – Can be configured as a digital (square wave) input or an inductive input

20 - 12v PWM Outputs – Can be configured as PWM or switched 12V outputs. Rated at 2A maximum

16 - Ground PWM Outputs – Can be configured as PWM or switched ground outputs. Rated at 2A maximum

All inputs and outputs are programmed using innovative new “Pin Mapping” strategy that allows inputs and outputs to be pinned as desired by the user, allowing for inputs and outputs to not be “wasted” by non-used dedicated functions

Configurable for: dual cooling fans (including brushless fans that require PWM signal), dual fuel pumps, AC inputs, basic TCC lockup, and multiple timing retard inputs

User programmable caution and warning outputs for all sensors

ADVANCED TUNING ICF
