Scott Posted May 30, 2012 Report Share Posted May 30, 2012 Good morning, In PCLink is your RPM reading correctly, or is it also 2000 RPM higher than it should be? If it is only your tacho in your gauge cluster that is reading higher, where does the signal come from for the tacho? Regards, Scott Quote Link to comment Share on other sites More sharing options...
