IGBT High Current Ignition Driver Components
Current Limiting Circuit Components
That's right, every single option to enable every single feature this great ECU has to offer.
The MegaSquirt 2 Standalone EMS is the latest product from Bowling and Grippo. Truly the dream ECU computer for the DIYer. This latest rendition can control fuel, ignition, stepper motor IAC, and more for your turbo, supercharged, or naturally aspirated engine. More information about MegaSquirt-II can be found at
http://www.megasquirt.info/ms2.
MegaSquirt II includes all of the features and benefits of the original...
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 and wideband O2 sensors.
Log data on your laptop for later analysis.
Tuning software is free for download and regularly updated with new features.
Open Source design - all code and hardware information is available online.
Includes proper female DB37 connector and shell for building your wiring harness.
Additional Features new to the MegaSquirt-II
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,
115,200 baud serial interface with MegaTune2.25+,
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
