New owner of an 84 T-type. My Speedometer is off by around 25%. At 20mph it reads about 5 mph fast, but up over 60 its reading about 15mph fast.
The rear has 255 60 15 Tires on it, so I think that should make me read about 3-4% LOW, right??
I don't have a scanner yet, so not sure what the ECU is reading.
Is there any kind of recalibration that can be done on these speed-o's or is what I need a new speed-o gear for the trans? Does this mean that someone has changed the rear end gear in this car? How would I check that out?
Thanks
