So how is that achieved? I want this to be on the safe side, and I can get the mixture how I want it, but the advance mapping is a bit of a mystery to me.  

 

Some tuners temporarily fit a knock sensor. But you can hear knock too, so you can still keep advancing until you get knock and then retard a bit.

 

With 97 RON fuel especially 34 degrees will almost certainly be safe. 32 degrees would be safe with 95RON supermarket fuel (just figures based on some experience of my own and what people on tuning forums end up setting theirs too)

 

Manufacturers seem to end up fine tuning the timing in order to create the character of the powerplant suitable for the widest range of riders, it's why we see the low gear torque limiters on many bikes to keep the front end from coming up on a novice rider.

 

I think aswell there are some implications for emissions limits but I haven't looked into that much, but it's certainly easier for manufacturers to tweak a 'global' timing map than it is to start to retune fueling maps when all they're trying to do is make an engine a bit more user friendly.

 

A +4 degree advance kit is available for most bikes, and it's accepted that most bikes can run with at least another 4 degrees of advance safely. If you had an original map you could start just by adding 4 degrees across the board.

 

I'm working away from home a lot recently (Sunderland) but if I get the chance I'll try downloading the map from the Samios ECU and comparing it to the untuned data I already downloaded before sending it off.
