For a Gen2 FJR, you must get a PC5. A PC3 from any other bike, including a Gen1 FJR, will have the wrong connector for your wiring. Also, if you want to do the job properly, you need an Autotune unit with a new O2 sensor to go with the PC5. Without the Autotune unit, any map that you program into the PC5, will only tune the engine for one particular set of atmospheric conditions. When those conditions change, as they will due to temperature, pressure, altitude, and humidity, there is no feedback loop to re-tune the engine.
