[QUOTE="UselessPickles, post: 866176, member: 3256"] You missed that discussion just a couple of posts back :) I was also further convinced yesterday that I should at least avoid cruising mode in 1st and 2nd gear. I got stuck in some slow traffic on the freeway and was staying in 1st/2nd for instant acceleration if needed, and hopefully the noise would help prevent a car next to me from swerving over. I quickly disabled cruising mode with my nifty button because the lean surging that is barely a slight annoyance in 3rd/4th/5th is quite a problem in 1st/2nd. I currently don't have any speed or gear info. Only RPM and throttle position. I could get gear position by tapping into the bike's gear position sensor wires with a couple resisters and diodes to generate an analog signal that jumps between 6 different values for the 5 gears and neutral. I think that would be easier to get working correctly/quickly than calculating speed from the 42 pulses per rotation of the wheel, especially since I'm pretty sure I only have one timer on the chip that I can use for the built-in capture feature (captures the value of the time when a pin switches from low to high; when a pulse happens). I'm already using that feature for calculating RPM, and I'm resetting the timer after every pulse, so I can't reuse it to also calculate speed. [/QUOTE]
