As I am ignorant when it comes to bike ECU's and electronic wizardry, could you explain your posts please? It's never too late to learn! - Simon
All modern engines has a computer that is controlling them. Most of the time called ECU. The ECU has software that dictates how the fuel, ignition and other things will behave. The programming of the ECU is made by the manufacturer. It is a sort of average setup that sort of works on all bikes. It should work everywhere, at all different temperatures, air pressures and all different fuels. It also has to follow the regulations with regards to emissions and noise. In general it is always possible to make a serial produced bike to behave much nicer and be more powerful by optimizing the ECU software (the map)
As I always wants to modify my bikes. It could be just an optimization or something bigger like bigger bore, different cam shafts or cam timing, head porting, different induction system different exhaust system I also need to be able change the ECU software to something that fits my configuration. On top of that for me it is not that important that my bike follows the regulations with regards to emissions and noise.
Different bikes has different ECUs and different models of the ECU. That's why I want to know what ECU the scrambler has.
Does that explanation make sense?
