MegaSquirt MS3-Pro EMS

$ 1,150.00

Hardware features:

  • Freescale MC9S12X 16 bit, 50 MHz asymmetrical dual core processor
  • 10 saturated injector drivers
  • 8 logic level ignition outputs
  • 3 high current (5 amp) general purpose outputs - 2 can be reconfigured as additional injector drivers
  • 3 medium current (3 amp), high frequency general purpose outputs
  • All unused injector and ignition outputs can be used as SPARE outputs.  This ECU has a LOT of I/O!
  • 1 stepper H-bridge driver
  • Camshaft and crankshaft differential inputs - supports VR, Hall effect, and optical input
  • 12 volt tach output
  • Fuel pump output
  • 8 analog inputs (5 dedicated sensor inputs, 3 spare/general purpose)
  • 4 spare digital on/off inputs
  • 3 spare digital frequency inputs
  • 2 knock sensor inputs
  • RS232, USB 2.0, and CAN communication
  • Onboard 8 gigabyte SD card for internal data logging
  • Internal ECU temperature sensor
  • Real time clock
  • Temperature range: -30 to +80 degrees C (-40 to +85 without battery for real time clock)

Software features:

  • Supports speed density, alpha-N, or MAF based fuel and spark tables
  • 1 microsecond injector pulse width resolution
  • Tables for nonlinear injector behavior at small pulse widths
  • Allows blending multiple load types, including specialized mode for independent throttle bodies
  • Supports a wide variety of OEM cam and crank position sensors
  • Individual cylinder trim tables for fuel and ignition
  • Accelerator pump or model based acceleration enrichment
  • Closed or open loop idle speed control
  • Closed or open loop boost control with gear or speed based tuning options
  • On/off or closed loop continuously variable valve timing control - supports up to 4 channels
  • On/off or progressive nitrous control
  • Traction control
  • Rally anti-lag
  • Rotary support - can run up to 4 rotor engines with separate leading and trailing spark tables
  • Staged injection
  • Table switching
  • 16 x 16 fuel and spark tables - can be reconfigured to function as 30 x 16 or 16 x 30 by switching tables based on RPM or load
  • 2 or 3 step rev limiter with no-lift shifting
  • Wideband AFR target tables
  • Flex fuel sensor input
  • Allows repurposing injector or ignition outputs as general purpose outputs, or high current outputs as injector drivers for 12 cylinder sequential applications
  • Real time barometric correction
  • A/C and cooling fan control with idle compensation
  • Safety shutdown based on AFR or EGT input
  • Sequential shift cut and air shifter control
  • 6 General purpose on/off or PWM inputs
