Resurrecting this thread as someone may know the answer to a question I have.
Apart from the power restriction we know about, how else does the gear position affect the behaviour of the ECU? What would be the effect of modifying the wiring so that the ECU thought it was in e.g. 4th, all the time (apart from when in neutral of course)?
Since we now know that some bikes have restrictions in 1, 2, 3 and 6, forcing the ECU to think it was always in fourth would prevent any restriction, but what other effect would that have?
I've not been able to think of any other reason for the ECU to know what gear it is in. Anyone any ideas about this?
Please ignore the fact that the gear position indicator would be useless as that's not relevant to what I'm trying to do. I just want to know if there would be any detrimental effect on how the ECU ran the engine.
