Many of us are retired and have taken the time to get the cars right mechanically and electrically for the sake of reliability. We have either done it ourselves or with the assistance of our JH friends (both local and remote). I’m interested in getting my tach to read accurately. I know how to calibrate to a running GPS device and working backwards based on tire size, transmission and rear end ratios. I also have work to accomplish in getting a working speedometer that I can calibrate to my custom gear ratios. I have a 4!speed and am using 205/60/15 wheel/tires on the rears.
