I like the electronic speedometers also. Like Roscoe, I have one except mine is a VDO. I went to a police test and they let me run their radar setup at 50,60,70,80, and 90 MPH and the speedometer and tach were both right on after I did the math to find out the exact RPM.I can't read 2525 RPM on my tach but at 60 in 4th it was reading just above the 2500 mark and 2525 is what the math shows it should have been. It is exactly on in 5th at 70 when I tach 1900 RPM. If I change tires or gears, I just start the car while holding the button in until it scrolls to automatic, then drive a mile. Stop and push the button and it calibrates the speedometer. I tried it once by driving just past the mile marker a little ways and it put 2/10s on the tripometer and told me I had driven 1 & 2/10s miles.
