I brought a tiny tach, how do i make it work for a 4 cyl?<br /><br />I connected it up as per the instructions, and it reads stupid numbers ie on tick over about 3290rpm, which i know is false.<br /><br />Any ideas?<br /><br />it says it can be used with one or two cyls. But i could not find on there website for 4 + so i dont know if i have the right one..<br /><br />Any help would be grateful<br /><br />Stuart
