MegaSquirt 2 EMS (with MS2 Extra firmware) stand alone engine management system assembled with the latest surface mount PCB3.57 with brushed aluminum case

If there’s a feature you need, chances are MS2 Extra can do it!

  • Cam/ crank wheel decoding for a stack of different ignition system trigger wheels
  • Coil on plug/wasted spark ignition
  • 16×16 Volumetric Efficiency (VE) and 12 x 12 Ignition Tables
  • Boost control
  • Shift Light control
  • Water Injection control
  • Knock Sensor Input
  • Staged Injection
  • 2 Stage Nitrous Control

Features / Benefits of all MegaSquirt EFI Systems

  • Onboard MAP sensor for NA or boosted engines up to 21psi! 
  • Speed density or Alpha-N.
  • Use any injector – High or Low impedance.
  • Compatible with output from narrowband sensors and wideband O2 systems.
  • Log data on your laptop for later analysis.
  • Tuning software is free for download and regularly updated with new features.
  • Source code and hardware information is available online allowing you to customize things beyond the massive featureset already available if you choose.
  • Includes proper female DB37 and DB15 connectors and shells for building your wiring harness.
  • Professionally Machined Brushed Aluminum Case with Endplates. Excellent Fit and Finish! Flanged for easy mounting.
  • Supports use of original MS tach input, ignition coil triggering, VR, Hall and Optical sensor triggering.

MS2 Extra MegaSquirt 2 processor-specific features:

  • 24 MHz HCS12 processor
  • Fuel control to 1 µsec (100 times more resolution than MegaSquirt-I)
  • Ignition control (full spark timing advance control, dwell control, etc) for one coil/distributor (7 pin HEI for example) and Ford’s EDIS systems
  • On-board stepper motor driver for IAC stepper control (we install the jumpers for this by default)
  • Ford PWM idle valve firmware support
  • Built-in rev limiter, either ‘fuel cut’ or ‘spark retard’
  • All tables are now 12×12 in size
  • WBO2 AFR target table (in AFR units)
  • Independent dual-tables for VE and AFR target
  • EGO feedback in wide-band mode is proportional to the difference between the measured AFR and the target AFR, the bigger the difference, the bigger the feedback step
  • Spark advance table can have different rpm and kpa bins than VE and AFR tables
  • CANbus networking
  • Barometric correction amount and direction configurable in software, and provisions for:
  • barometric correction based on initial MAP reading
  •  independent 2nd barometric MAP sensor for continuous real-time baro correction or
  • no baro correction.
  • TPS values for open loop and flood clear mode are user configurable
  • MAP based open loop can be set as well as TPS
  • Both TPS and MAP based accel enrichment is built into the code, you can configure the ratio of each
  • Blended Alpha-N and speed density is an option
  • 2 spare I/O lines for custom controls. (This is in addition to 4 lines for Idle stepper control if you don’t need this, or the Fast idle solenoid then becomes a spare if you do use a stepper motor.)
