I'm looking into purchasing a lap timer for my bike. I was wondering if anyone has any experience using the new MyChron 3 (i believe it came out last summer). I know most racers use the MyChron light MCL and MCR, but i can't say I've seen the MyChron 3 or 3+ on a race bike before (i know their big in the karting world)?? The 3 is bigger then the others, but it has a tach and temp input as well as keeping track of lap times. I was wondering if I could just use this as kind of an all in one? The MyChron 3 Plus comes with wheel speed and gear position sensors for an extra $165 i think. Has anyone had luck using wheel speed sensors to their advantage?
