Worked out good, do not know how accurate it is since I did not check it. There is a slight up date time, so RPMs are not displayed instantaneously (every second or two) . I was interested in a cheapo for seeing where my personal shift points are, and for setting up the carb idle.Had to program differently than I though so it would display correctly (do not remember the details). Had to use less wraps around the spark plug wire than instructed (think too much electrical noise messed up the readings. I got the cheapo - non replaceable battery, no back light. Hard to see with polarized sunglasses. I mounted mine with Velcro, so can take it off - have to order the right model that has a flat back), Velcro used so no need to drill holes. Nice thing about this one is you can order it with longer leads, extra length was need the way I routed the wires. Most LCD tachs are supplied with very short wring and usually warn you not to splice on longer wiring - reasons not given in their documentation. Can not be turned off to conserve battery, but is still working. I could move it onto the dash plate so it is illuminated by dash light for night driving.
