This means that whatever voltage coming in will go out to the ECU, minus 0.6V or so forward voltage (Vf) for a silicon protection diode. Power supplied to the sim will be supplied to the ECU, through a diode and PTC fuse. If you'd prefer to purchase with a power supply that is ready to use, select the "Engine Sim Plus Power Supply" option. In addition to many “wall wart” style adapters, the 12V rail of an AT/ATX power supply (yellow + black color wires typically) is suitable. There is not a single “right” power adapter for this – you could even use a variable voltage supply to investigate behavior of the ECU under different power conditions. Alternatively, wires can be soldered to “CONST PWR” and “GND” instead of the barrel jack. The sim has a center-positive 2.1mm barrel jack for power. The Sim v3 bare kit is supplied without a power supply. bright LED for the IACV to visually verify the IACV circuit is working. Note: The engine simulator can NOT simulate idle air control valve behavior well enough to avoid a Code 14, so you will always have a code 14 present for the IACV unless disabled in the ROM/program running on the ECU. This provides a means for testing ECUs outside of a vehicle and observing many common faults such as damaged injector drivers, fuel pump drivers and distributor VR sensor amplifier damage. Outputs like injectors, ignition control module (ICM) and solenoids can be observed via LEDs. Controls are simple: on/off switches and knobs to adjust values up and down. It supplies the signals from the distributor and many sensors so that an ECU can be fooled into thinking it has a functioning, running engine connected when it is safely on the bench. The Honda EngineSim was introduced to allow interactive bench testing of Honda ECUs. The bare bones kit is for those who would like to build their own harness and provide their own power supply, while the complete kit is a quick solution to begin using the simulator as soon as you receive it. The engine simulator is available as a "bare bones" kit with just the board itself, or as a complete kit with power supply and harness with OBD1 ECU plugs attached. This is great to be able to isolate the ECU from a vehicle and test functions of the ECU that would otherwise be able to duplicate or test on the vehicle. Testing on the bench allows complete testing to verify circuit operation, etc. The OBD1 engine simulator allows running and testing of OBD1 (and other compatible) Honda ECU's directly on the bench.
