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.)
