Power Button Dyno

RyuHayabusa · 05-05-2010, 01:19 PM

Does anyone have a dyno overlay with power button and without, wondering what the curves look like and if there is any difference.

Thanks

All 'power' button does is make the throttle map steeper; it has no effect on power, other than if you're at, let's say, half throttle, you'd have the butterflies open about 50% with 'normal', and maybe 60% with 'power', meaning you'd reach WOT sooner with 'power', and even sooner with 'power plus'. If you mash the throttle (like on a dyno run), settings won't matter as you'd be at WOT regardless.

Ah ok, so it's acting like I'm depressing my throttle more than I actually am.

Thanks for the clarification
