Quick Question on T-SB-0148-16

Had my module replaced a few months ago. I've no noticed the analog and digital MPH don't match. Depending on the speed there's a 1 - 5 mph difference between the two. Anyone else have this problem?

 

Mines off by 1 MPH.

Normal.

 

Kind of what I thought but just asked to be sure.

 

There was a thread where this topic came up and the mass consensus was they were off. I checked mine against my handheld GPS and found the digital gauge to be accurate, while the analog one was off. It doesn't bother me since I never have both displayed at the same time anyways.

 

Is not what your analog, digital or GPS displays as speed.
Is WHAT the cop radar says.

 

I read an article once that stated that analog (this was before digital was prevalent) speedometers were typically set 1-3mph slower than actual at the factory.

Through using GPS on previous cars, I found this to be generally true.

 

Oh how true!

 

Sometimes its just what the cop says the radar says.

 

Aww Harry they wouldn't do that now, only if you're from out of state & won't be going back to court!
