Assuming you even have it!
For some reason I seem to be more active on YouTube than here. Pretty pictures! You guys seem to be much better informed and civilized than other corners of the Internet.
Scotty Kilmer posted a video about saving gas and gave the standard tips about replacing your air filter, using the right oil and tire pressure, and driving conservatively, but he also introduced something called "Wind Booster" that adds eco, sports, etc. modes if you have an electronic throttle.
I cannot find out much about it, just that it reduces throttle response in eco mode and increases it in sport mode, because stomping on the accelerator is so difficult--or people want to pretend they are driving their car hard, while still being able to afford gas.
Who even uses Eco mode?
I don't have it!
