[QUOTE="Magnetoman, post: 106557, member: 2806"] Sorry for not having responded sooner. Having just finished my Federal tax forms a few days ago (due on April 15 in the U.S.), the phrase "financial statements" caused my vision to blur and to temporarily lose consciousness. I made a "universal" position sensor based on a potentiometer and 1.5 Volt AA battery that clamps to the handlebars. I don't remember the value of the potentiometer I used (something like ~50 kOhm) but with the 1.5 V across the outer terminals the drain is negligible, and with one the lead to the data logger from the center terminal the signal goes from 0 V with the throttle closed to 1.5 V fully open. The LM-1's resolution of 5 mV gives the equivalent of a 0.3% change in throttle position with a 1.5 V battery which is why I don't bother with two or three batteries (the max. input to the LM-1 is 5 V).
