Megasquirt 3 Ecu Only
MegaSquirt 3 Engine Management System w/PCB3.57 – The MegaSquirt 3 is a drop in daughter card that greatly expands the MegaSquirt’s functionality. This model is equipped for basic, batch fire, but can be expanded to add sequential injection and 8 channel ignition control with an MS3X card (sold separately). Advantages include loads of additional processing power, speed, and features over the existing MS1 and MS2 systems. The MegaSquirt 3 daughter card alone provides 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
Ready for two fuel outputs and one 5V logic level spark output. The MegaSquirt 3 also gives you a starting point for even more expansion. Further expansion with MS3X enables features like:
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
