I've actually looked into using a bicycle computer as a tachometer for my wife's Eurovan. It is trivial to hook up, and one can compensate for the 5-cyl. engine using the tire size calibrator (most J.C. Whitney and other tachs are not set for 5 cyl. engines). One small problem: when you hook it up, (I beilieve) the counter is wrapping back to 0 a little too quickly, so under idle, I get a cyclic pattern of readings (typical). A set of dividers made of flip-flops is not too hard to do, but like everything, I'll probably get around to it in the next two years or so. Good luck, Cetin
