Software/Firmware Features

  • Supports speed density, alpha-N (TPS based), 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 two separate wastegate outputs, and gear or speed based tuning options
  • On/off or closed loop continuously variable valve timing (VVT) control – supports up to 4 channels
  • On/off or progressive nitrous control
  • Traction control by VSS or RPM
  • Rally anti-lag with rotational idle
  • Wankel 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 (launch control) with no-lift shifting
  • Wideband AFR target tables
  • Flex fuel sensor input for easy switching between gasoline and E85 – can automatically change fuel, ignition, and boost maps based on ethanol content of gasoline
  • Knock control with adjustable crank angle windowing can adjust sensitivity based on RPM or which cylinder is firing
  • Allows repurposing injector or ignition outputs as general purpose outputs.
  • Real time barometric correction (external sensor required)
  • A/C and cooling fan control with idle compensation
  • Safety shutdown based on AFR or EGT input
  • Sequential shift cut and air shifter control
  • Diagnostics to detect and ignore failing sensors – can even automatically switch from speed density to alpha-N in the event of a MAP sensor failure

The MS3 daughter card on its own will give you all these features and more:

  • VE and ignition tables are both 16 x 16 with full interpolation.
  • 0.1% steps on VE table, 0.1 degree steps on ignition table
  • Socket for an onboard SD card – no laptop required for data logging  (SD Card not included)
  • Built in USB port
  • GM stepper IAC control
  • Closed loop idle and mixture control
  • CANBus communications for interface with GPIO Board, IO Extender, or other devices
  • Staged injection
  • Native support for many different OEM trigger patterns
