V11 Fuel Consumption

[stefano]

every time i fill up (premium of course) i always do MPG (US gallons)

it's always 37-40 mpg, doesn't seem to matter how i ride it, almost always the same.

and the tripometer seems to be right on, although the speedo says 85 when we're doing 80 (and the odometer packed it in couple thousand mi. ago)

has mistrals & power commander. bike will ping (loudly) when warm & accelerating hard in one gear too low, so i keep the revs up, bike is happy. she runs great.

i've never seen my low fuel light on, don't know if it works, but have never gone beyond 160 miles.

cheers, stef

I changed my ECU to one from the Racing Kit - factory ECU meant for the Titanium exhaust. What a difference. My fuel burn went from about 40-42 (UK) to 50-51 (UK) first ride. I have not even taken the time to adjust CO levels or check TPS voltage - let alone play with the power commander. Very pleased with the performance as well - no glitches and more responsive midrange.

 

I have FBF high comp pistons and FBF exhaust valves plus Stucchi crossover and Mistral exhaust - I may put the Titaniums on but for now I'm happy!

That's impressive indeed. My experience with performance ECUs (Termi, EVR, Akrapovic) is that they throw more fuel in the belief more airflow = lean running. I removed the Termi ECU from my PS1000LE 2:1 system because it cost 5 - 7mpg and fouled plugs. Sounds like you have a winning combination. Does it still pink like stock?

It did not have serious problems before as I would always try to use good fuel and not LUG the engine but with the KIT RACING ECU I did not have any noticeable change in the effects of "pinging" on the engine. In fact it seemed that I could induce full throttle at 4,000 rpm with no pinging at all which is an improvement .... different than some people with stock systems!! I know that it is considerably different what I have on my bike but I am very pleased with the results! I can't wait until I get to a dyno ....

 

Oh .. and yes ... I never thought I would have better fuel consumption but then my bikes configuration is different than most but I always thought higher compression meant better midrange and better fuel economy ....
