Description
MegaSquirt-III Engine Management System w/PCB3.57 – The MegaSquirt-III is a drop in daughter card that greatly expands the MegaSquirt’s functionality. This is the basic, batch fire version, but can be expanded to add sequential injection and 8 channel ignition control with a MS3X EXPANSION BOARD As it is, you’ll gain a more processing power, speed, and features over the existing MS1 AND MS2 systems even without the MS3X. The MS3 daughter card on its own will give you all these features and more:
- VE and ignition tables are now both 16 x 16
- 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
This unit is set up for two fuel outputs and one 5V logic level spark output. The MS3 also gives you a starting point for even more expansion. You will be able to connect the headers on this board to additional hardware, such as the MS3X EXPANSION BOARD to enable features like these:
- 8 channels sequential fuel control
- 8 channel sequential ignition control
- Individual fuel and spark trim for cylinder by cylinder tuning
- 2 and 3 channel PWM IAC control
- 2 stage nitrous controller
- Table switching for multi-fuel engines
- 2 step launch control
