OK, I'll post this as a potential source of information for anyone interested.
My 1150 has a few bits fitted which are not standard (all declared on the insurance of course) and I decided to fit a Power Commander to have things running to their "optimal" levels.
Took the bike down to Brian at Mototech to have a custom map made up on his Dyno. personally I'm not after top end power (although we had a little fiddle and got a map for that as well
) and the graphs show the results.
Personally there are so many factors which can influence the results of a Dyno run that I don't go with comparing runs on different bikes taken at different times on different dynos but on the same day on the same dyno I think they are a useful tool.
Right the bike, 2004 1150 GSA, 11237 miles on the clock, Remus y piece, Akrapovic end can (baffle removed) K&N air filter and Wunderlich power snorkel fitted (all bar the end can came with the bike when I got it honest
).
First off a base run with no Power Commander.
Pretty much confirmed the suspicions that the changes made had left the bike running lean (although I never had the chance to run it as stock), the air fuel graph showed that the fueling was off the scale and no where near the optimal fueling indicated by the dotted red line.
After mapping the results showed the difference that had been made.
So much for the rolling road, is it noticeable on the real road with the good old arse dyno? Well I have to say yes the bikes smoother, crisper off the throttle and IMPO even more enjoyable to ride, but of course that's all subjective.
Having got a map as I wanted it we went on to see what could be done for top end power, got to be honest not something I'm looking for but as it was on the dyno and the bits I wanted to fit were in the top box we gave it a go.
As you can see the increase in top end power came at the cost of a reduction in torque , as torques what's important to me I'll be running with the original map but if for some reason I want top end I can easily load the map and make the physical change to the bike, what that change is I'll let anyone who wants to have a guess for now.
