Hi everyone, am I wrong, or does the booster plug simply modify/ fool the ecu into reading a lower intake temperature when opening the throttle from a closed position. ? Thus giving a richer boost or less of a delay in acceleration. Bit like pumper carbs.
The Booster Plug website gives lots of info and graphs. But basically, yes, it fools the ecu into thinking it's 20 degrees (C) cooler than actual, resulting in about 6% more fuel. Occurs only during 'open loop' operation, not steady state/closed loop. Surprisingly, my first fillup with the Booster Plug gave no change in mpg. Still at 70. So the small adjustment only during throttle change is small enough to be almost undetectable in mpg, but very noticeable in drivability.
I like it so much on my RE that I just ordered one for my KTM Duke 390!
