The IO Extender w/ 8 ft. Harness firmware allows the use of a Microsquirt as an IO Extender w/ 8 ft. Harness with minimal D.I.Y. and straightforward
software configuration. When used with MS3 or 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 outputs
By design, the inputs and outputs have a fixed function to simplify configuration. All configuration is performed through TunerStudio in the MS3 settings pages.
