• Speed density, Alpha-N, Alpha-N Combination, and VE fueling strategies – Tuner has the option to select from a variety of load sensing strategies to meet their engine requirements or tuning preference
• Individual cylinder fuel and spark control allows you to unlock your engine’s potential
• Unique lb/hr based fueling strategy greatly simplifies and commonizes tuning
• Advanced idle, closed loop, and enrichment strategies allow for very stable engine operation
• 1-7 Bar MAP sensor capability – For naturally aspirated or boosted applications
• Fuel Map and Learn Function Smoothing – Helps to smooth rough areas of the maps
• Configurable User Password Protection – “Lock” your tune to prevent tampering
• Self-tuning fuel table strategy greatly simplifies tuning process – The more you drive it, the more it learns
• “Quick Start” strategies – For faster engine starting
• Allows for use of common OEM sensors as well as custom sensor calibration input
• Two channel knock control sensor inputs for both one or two wire knock sensors
• Dedicated fuel and oil pressure inputs
• Controls both stepper and PWM Idle Air Control (IAC) motors
• 3 Rev Limiters – Choose between 4 options for each: Fuel Only, Spark Only, Fuel and Spark, or Soft
• Traction Control – Allows power reduction via timing, nitrous percentage or boost (Requires Davis Technologies Holley Module)
• Store and select between four calibrations with Multi Map Selector (Part Number 558-407)
• HARDWARE
• ECU is fully potted and can be mounted in the engine compartment or interior – See images for dimensions
• Sealed automotive and marine grade connectors
• Optional Digital Displays – 7″ Digital Dash (PN 553-106) / 3.5″ Touch Screen LCD (PN 553-108)
• 12.3″ Pro Dash (PN 553-111) and 7″ Race Dash (PN 553-106) features full gauge layout customization, and nearly limitless tuning options.
• DATA VISUALIZATION TOOLS
• Data Logger –Analyze and export your data with sophisticated, but user friendly tools – Internal logger has 4 GB of memory
• Strip Chart – For real-time data viewing
• Fully Configurable lap top Gauge Panel – Life-like gauge cluster on your laptop screen
• Racepak Integration Module Available.
• Data logger – Smoothing, multiple graph view, pre-defined notes fields and more..
• 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
