Replied in the other post But the things that control both the fuel and ignition maps are the revs and the throttle opening, these are then trimmed by the various sensors to get the mixture correct. As such a problem with either the TPS or the crank sensor is fatal for the bike as these are the main inputs to the ECU, there are a several other inputs, as mentioned there are other sensors such as Air and water temp, then there are a couple of Interlock inputs, most of which prevent the bike cranking over when in gear, such as neutral & sidestand Outputs from the ECU are mainly the Ignitin pulse to the coils and the injection pulse to the injectors, via the power commander in your case which also taps into the TPS signal. This it usually does with a very poor connector that can if not careful braeak the TPS wire preventing the signal getting to the ECU Not sure which ECU a you are running Has the bike been running OK previous to this isssue Checkout the Desmo Due Paddock on Facebook |
