AxiomEFI 600 ECU

Description

---

Overview:

The AxiomEFI 600 Engine Management System is a 3-connector standalone ECU useful for racing applications. AxiomEFI provides superior engine control for fuel, ignition, VVT, boost, and other systems. It is recommended for up to 8 cylinders or up to 4 rotors. Featuring dual throttle control, electronic waste-gate control, learning functionality, dual channel knock control, and several other critical features, the AxiomEFI 600 Engine Management system covers all racing needs. To make calibrators’ jobs easier, AxiomEFI Engine Management Systems feature AxiomEFI Tune: a fast, lightweight, user-friendly tuning software package for calibrators’ PC laptops.

Hardware and Functionality:

• Dual-core 200MHz safety-enabled 32-bit processor with dedicated timing co-processor
• Support for 1-12 cylinder engines (Recommended for up to 8 cylinders, but supports up to 12)
• Support for 2-4 rotor engines, including support for factory Mazda ignition systems (or custom)
• Staged, sequential, semi-sequential, and batch injection
• Coil on plug, wasted-spark, and distributor-based ignition systems
• 8 half-bridge outputs to control (at the same time):
  • 2 drive by wire throttle bodies
  • 2 electronic waste-gates
  • (outputs can also be used for other applications, such as stepper or pwm idle motors)
• 8 peak-and-hold fuel injection outputs (high-Z or low-Z injectors)
• 8 spark outputs
• Low-side outputs:
  • 2A outputs:
    • 5 with software-configurable +5v, +12v pullups, and configurable recirculation
    • 2 with configurable recirculation
  • 4 10A outputs with configurable recirculation
• 2 EGT inputs
• 2 built-in wideband O2 controllers (Bosch LSU 4.9, other Bosch sensors supported with later firmware updates)
• 6 frequency inputs (VSS, MAF, Flex Fuel, Wheel speed, etc..)
• 5 Differential VR/Hall inputs (Crank/4 cams)
• Variable Valve Timing support for up to 4 cams
• 14 analog inputs (11 with selectable pullups)
• 1 RS232 port (GPS/Bluetooth connectivity)
• 1 USB port
• 2 CAN channels with support for communicating with several aftermarket CAN devices
• Built-in Inertial Measurement Unit (Accelerometer and Gyroscope)
• On-board Datalogging – 32GB of storage at up to 1000Hz
• Highly robust hardware design

Features:

• Low Impedance injector control with programmable peak and hold duties and times.
• Support for 2 Throttle by Wire throttle bodies – requires pedal input (2 analog inputs) for a single pedal, and 2 analog inputs + 1 throttle output (2 wires) per throttle. Throttle outputs can be used as outputs for other features if not used by throttles
• Support for 2 Electronic waste-gates – requires 1 analog input and 1 e-gate output (2 wires) per waste-gate. Outputs may be used for other features if not used by waste-gates. Can be used at the same time as the 2 throttles.
• Closed loop short-term fuel trim with built-in lambda sensor controllers. Control 2 banks with built-in lambda, or up to one per cylinder with multiple external CAN-based controllers
• Long-term fuel trim/learning – can be tuned to be as fast or slow changing as desired.
• Support for stepper (requires 4 or 6 wires depending on the motor type), and 2 or 3 wire PWM idle speed controllers (requires 1-2 wires respectively) with closed-loop control.
• On-board datalogging – up to 1000Hz and PC datalogging (up to 50 Hz). 32G internal storage. Fast download of internal datalogs (typically 2-3M/sec.)
• Dual knock control inputs with high-speed internal band-pass digital filtering
• Staged injection with up to 2 stages and different sized injectors for each stage
• Boost control (closed and open-loop, CO2, e-gate, and standard solenoid) with boost by gear, boost by road speed, etc.
• Dynamic tuning table resolution up to 31×31 on specific tables
• Custom calculations and tables with user-selectable Axes to modify fuel and ignition timing – implement your own accel enrichment, traction control, and other strategies.
• Advanced engine protection strategies
• Fan control – PWM or on/off
• Fuel pump control – PWM open/closed loop and on/off
• Alternator control (PWM closed loop and High-speed field control)
• 16 custom sensor inputs – can be used for logging. All non-generic features that require I/O have their own inputs
• 16 custom outputs
• Dual-fuel and flex-fuel support
• GPS input for speed and datalogging
• Up to 12 lambda sensors (via CAN)
• MAP prediction
• Several load calculation modes
  • Speed Density (raw MAP or percent of barometric pressure)
  • Alpha-n
  • ITB-mode (merges alpha-n and Speed Density for incredible tunability)

Racing:

• Nitrous control
• Launch control
  • 2-step/3-step
  • Trans-brake
  • Line-lock staging
  • Flat shift
  • Throttle-stop
  • Timed ignition retard after launch
  • Wheel-speed based launch
• Timer functions
• Pit-lane limiter
• Water Injection
