Speedometer calibration?

You would have to talk to someone who does a lot of work on the Combination Meter. The ABS system takes readings from the wheel speed sensors and sends a Vehicle Speed Sensor reading out on the data network. The CM receives the VSS data and displays it as a number on the speedometer.

You could reach out to someplace like TexasHybridBatteries.com and find out if they can do anything like changing how the speedo displays the VSS data.

I mean how much big of a tire are you going and how high are you going I'm 40 mm and could only get a 27-in tire I would be almost wheel well liner to wheel well liner and all that so then that has to come out now I have no wheel well liners or I go up higher so are you going high enough to get 35-in tires on so your tires are about 12-in taller 14-in taller than the 25 or so outer diameter of the factory because I'll just looked at with a tape measure a couple of times so don't quote the exact numbers so in reality the 10 or 12 in taller that you are now what does that really do to this speedometer mathematically throws you off what 6 miles an hour hell even 10 as long as you know what you're driving I can't even see the relativity of getting that adjusted outer whatever you'd call that like my motorcycles are inaccurate but I know what the inaccuracy is I can even rip the speedometer apart and pick the needle up off the post and move it over and guys do that stuff I mean for what I'm not really understanding because I'm worried I might get a ticket?.

 

I doubt it. Ditto for the odometer. Hacking either is possibly illegal, the odometer in particular.

 

I lifted mine 40 mm I still have the stock tire size on it I'm getting ready to go to 215 65 15 that's about 2 in or 1.7 in past or over the stock outer diameter for the car I'm not expecting any real drastics speedometer changes I can't wait to see right now I have none I'm just up and on the same factory 185 65 15s.

 

I lifted the car to make getting in and out easier and when I told my trailer the trailer sits more level
