  • Fuel Only
  • Spark Only
  • Fuel and Spark
  • Soft
• Data-logger
  • Analyze and export your data
  • Strip-chart allows for real-time data viewing
  • Fully customizable laptop gauge panel displays a realistic gauge cluster on your laptop screen
  • Blending, different graph views, and pre-defined notes/fields are just a few of the features available
  • 4 GB of memory
• 8-Stage nitrous oxide control
  • Nitrous control with full functionality eliminates the need for a separate nitrous controller
  • Wet or dry with closed-loop feedback compatibility
  • Lean or rich safety cutoff
  • Configurable timing retard/control on every stage dependent on RPM or time
• Control for water/methanol injection
  • Allows for the control of two nozzles (400 to 1000 cc/min)
  • Complete fuel pump activation control
• Turbo boost control
  • Eliminates the need for an additional boost control device
  • Control boost based upon timing, gearing, speed, and manual inputs
  • Boost-builder setting Increases acceleration off the line by adjusting ignition timing, fuelling, and nitrous oxide activation
  • Anti-lag feature
• All sensors provide user-programmable caution and warning signals
• All inputs and outputs are programmed using an innovative new "Pin Mapping" strategy that allows the user to pin as desired, avoiding waste of non-used functions
• Provides dedicated inputs for fuel and oil pressure
• Two cooling fans (including brushless fans that require a PWM signal), dual fuel pumps, AC inputs, basic TCC lockup, and multiple timing retard inputs are among the features that can be configured.
• Inputs
  • (13) multi-use Inputs that can be used in a variety of ways, they can be set up as a 0-5 V sensor, a 0-20 V sensor, a thermistor temperature input, or a high/low voltage input
  • (30) 0-5 V sensor inputs
  • (4) Speed Inputs can be set up as either a digital (square wave) or inductive
• Outputs
  • (20) 12 V pulse width modulation (PWM) outputs can be configured as PWM or switched 12 V outputs (2 amp max rating}
  • (16) ground PWM outputs (2 amp max rating)

Notes:

• Parts required for a complete system are the main power, main engine wiring, injector wiring, and ignition adapter harnesses, also wideband oxygen sensors, and accessories (sold separately)
• Transbrake installation requires a relay or Holley 554-128 input protection device (sold separately)
• Not intended for use in high-heat conditions (under-hood mounting), and applications with a high continuous current draw
• Will drive 2 wire coils with the addition of Holley 554-112 four-channel coil driver module (Sold separately)
• Store and select between four calibrations using Holley 558-407 Dominator EFI multi-map selector (Sold separately)
• Optional digital displays (all sold separately)
  • Holley 553-108 3.500 in. LCD Touch Screen
  • Holley 553-106 7 in. Digital Dash
  • Holley 553-111 12.300 in. Pro Dash
• Progressive nitrous oxide control based on time, RPM, or boost, requires the use of Holley 554-111 high-current nitrous solenoid driver (sold separately)
