Are we having fun yet?
iOS acceleration app?
Is there a good iPhone app that measures acceleration like 0-60 and 1/4 mile time? I was surprised to not find any newer and popular one. Doesn't have to be race quality, just something to compare bike to bike performance differences 'cause butt dyno is so inaccurate. Some bikes feel fasters than others but I'd like to be able to get numbers on my own to compare against perceptions.
I was trying to think thru the effect of acceleration on a fast revving vs. a slow revving engine if they make the same power and torque, with the same weight and gearing. What makes one engine rev faster (freer, not higher) than the other? I think I knew this before but forgot. Found this interesting article:

Cool story. :laughing

She was at first startled, said nothing, and then flicked her cigarette at me....:facepalm
