MegaSquirt 3 ECU with MS3X Expansion

The MegaSquirt 3 with MS3X expansion arrives equipped with features surpassing MS2 & MS1 systems, like sequential fuel & spark, 2 step, progressive nitrous, boost control, onboard traction control & much more!

Are you on a budget, but still want complete control of your race purpose vehicle? MS3X has the features to give you a serious competitive advantage without breaking the bank.

MS3X Standard Features:

• 8 Sequential fuel injection outputs. Each can drive a high impedance injector, unused injection outputs can be re-purposed.
• 8 Logic level 5 volt ignition outputs. Works with many types of ignition modules and coils, including LSx coils and our IGN1A. Requires external module or coils with internal ignitors.
• 6 Medium current outputs. Use for 2 stage progressive nitrous, boost control, tach output, 3 wire idle speed control, general purpose PWM or relay control, or many other potential applications.
• 3 Analog inputs. Use for an external MAP sensor, second O2 sensor, fuel pressure, accelerometer, or general data logging.
• 4 Switch inputs. Can be used to start data logging, arm a nitrous system, switch tables, launch control, VSS input (Hall sensor or VR with external conditioner), and more.
• 1 Cam sensor input. Can be used with VR, Hall, or optical sensors.
• VE and ignition tables are both 16 x 16 with full interpolation.
• 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
