August 23, 20223 yr My Z's tachometer has always read high when compared to either Conzult or more recently also my Racelogic, which taps into the tach line from the ECU. For example, at warm idle my tach reports a smidge over 1k, while the Racelogic/ECU reports 850. This continues all the way through the rev range. I just wondered if anyone else has found theirs is the same or better yet if there may be a fix for this?
