I spoke directly with PC in the US today regarding this, as I have an interest in your question, and they gave the following answers :-
The 916 does not have a dedicated power commander model, and PC dont really recommend using another one, from a diff bike unless its fitted by an authorised centre. They told me that fast by ferraci have had some success of retro fitting say 748 or 996 PC's to the 916, starting with a base map, then running the bike on one of their dynos, and making the necessary adjustments.
All PC's come with a base map, for stock bike, stock exhaust. So what you would be up against is different fuelling for the two different sized engines, Ie 748 or 996, so best to start with a zero map and build from there.
I reckon John Hacket maybe a good place to start for dyno and PC on a 916
ANY PC3 willl work,as stated you will need a custom map doing on a dyno though.I think mine was a 748,junked the map and re-mapped for the 888SP5,no problem.
i am looking into the power commander option and have also looked at the FIM chip. I prefer the FIM but at the moment the thing that is clinching it for me is the fact that the fim software is 1500 bucks and the pc comes with the software.
in the uk its easy to go to a dealer of either and get it dyno'd but reason i must have the software is that im in greece. the rolling road guy here wont have access to it unless i supply it. they are a bit short on many things here and bike mapping software is definately one of them.
It might be cheaper then to fly Neil spalding over from Sigma performance UK with his handheld unit for the FIM and adjust it for you !! He can get an easy jet flight for pennies ?
with the power commander option, you could start off with a base map, then do your dyno runs, but you dont mention which dyno it is he has ? If its the 250 model, it will enable you to upload directly after a run, with the optimum map, taking into account the co readings etc.
If its not, then you will have to spend a lot more time doing runs, analysing your info and adjusting the map in increments, in order to get it right.
I have an FIM chip in my 996, and its does need tweaking, as it runs lean on the over run, so bear in mind that these chips do not solve all the problems, each engine / bike is slightly diff.
