Damn I knew that I read that ethanol blends can cause some serious deposits on the valves/head. Apparently the detergent package has to be very specific in order to keep them clean and its likely not every E10 blend will be good enough to ward out the deposits. I guess for those who do many km's per year should rethink about ethanol blends. For a bunga, who cares! Its good for them with the reduction in emmissions!
Oh yeah Cubes the 044 I have is dead quiet so I can't comment if the Boost98 makes it louder. My old 040 was crazy loud no matter what fuel it was running.
As for the enleanment 9kprm, I haven't really had a look. The PowerFC closed loop function is able to compensate for the E10 on cruise/idle but its kind of hard to use full throttle with my car whilst holding the LM-1 with my left hand and looking at the AFR. I'll have to get the logging properly set up and I'll post my results later on!
JazzaR33, oxygenated fuels doesn't mean that it'll burn faster or produce more power. Remember some of that oxygen in the fuel is displacing fuel that could be used so thats why enleanment occurs. I do not believe the oxygen in the fuel converts to O2 as such like in the air we have, but rather is an incompletely combusted compound (-OH) so its not the same.
