MicroSquirt with 8′ Harness CAN I/O Box Expansion
Microsquirt I/O Box firmware allows you to use a Microsquirt as a plug’n’play I/O extension box for MS3 or MS3Pro ECUs. It can offer a useful I/O addition:
-7 Analog inputs (0-5V variable)
-2 Wheel speed inputs (VR or hall type)
-2 Wheel speed (hall type) or ground-switch inputs
-1 dedicated ground-switch input
-2 high current PWM/switch ground-switching outputs
-4 mid current PWM/switch ground-switching outputs
-1 low current PWM/switch 0-12V output
-Perfect for capturing and logging vehicle speed and additional sensor data (e.g. pre- and post- intercooler temperatures, fuel pressure, oil temperature etc.)
To Use a GM 1, 2, or 3 Bar MAP Sensor with the MicroSquirt
In the illustration:
A is ground,
B is the sensor output signal to MicroSquirt,
C takes 5 Volts from MicroSquirt.
The pins are marked A-B-C on the sensor itself.
