This is my first Honda. I just saw the manual says to reset the ECM data whenever the throttle sensor and/or battery has been removed or replaced. I've had both the battery and carb out of this project bike many times and have not reset anything. It's not yet ready to test-drive, but I'm wondering what the purpose of the reset is, and what problems will present if the ECM is not reset.
Most electronic injection systems learn a bit about their components idiosyncrasies upon initial startup and run. They learn where 'closed throttle' and WOT are, some learn the idle setting, some learn how the injector(s) work, and so on. When you replace the Throttle Position Sensor, the computer needs to know how that particular sensor reads as closed throttle and wide open. IOW, what is the resistance at either end of the motion? In most cases, the computer will forget what it 'knows' about sensors if the battery power is removed for a long enough period of time. Some have a KAM - Keep Alive Memory - that carries information as long as battery power is applied, but forget it all after it is removed. Much like the saved radio stations in car audio equipment are lost when you replace the vehicle battery unless precautions are taken they forget. In that case, they are RESET automatically. If there is an internal battery, or static memory that needs no external power, a reset procedure would likely be publicized for technician use. tom
