To the group,
Has anyone recalibrated a P6 tach? I thought that the engine was revving
much lower than the tach indicated. I attached an external tach and there
was a 600rpm difference. There is a port? on the back of the tach that has a
rubber grommet and if you remove it there is a plastic slotted screw head.
Is this the screw that you turn? Regards, Larry
