The MegaSquirt Stimulator is the essential test device when building a MegaSquirt ECU. It allows the builder to simulate various sensor inputs and monitor the ECU's outputs.

The Stimulator allows you to simulate the following inputs to the ECU:
•Intake Air Temperature
•Coolant Temperature
•Throttle Position Sensor
•Oxygen (lambda) Sensor (Now switchable between narrow and wide band operation.)
•Engine Speed (NEW! Simplified single control setting.)
•Selectable positive or negative going RPM output (New in v2.2)

It has LEDs to monitor the following outputs:
•Fuel Pump
•Fast Idle Relay
•Injector drive (two channels)
•Ignition drive

This kit includes the PC board and all the components to build it.
