Of coarse once over sized tires were installed on my 150 the speedo is off. Not a problem as I use the speedo on the installed Edge programmer. Was wondering if there was a way to correct the speedo inside instrument cluster or if I must have this done at a speciality garage.

 

Your edge programmer will correct it. It's been a while since I did it, but I know it can be done. It well also help your shift points and mpg's once the tranny knows how big your tires are and what gears you run

 

Correct that the speedo in the Edge unit reads correct. The dash speedo is off like 10-15km/h at 90km/h. So the Edge programmer has the ability to correct the dash speedo???

 

you have to put in the circumference of your tire and that corrects the dash

 

I already did that and that made it possible for the Edge speedo to be correct. This had little to no adjustment for the dash speedo.

 

Huh.........when I did it my dash speedo was back to accurate readings. You stumped me

 

Lucky you and unlucky me.

 

Are you sure you selected "save previous settings" when you were making the change[s] in the Edge? Double check the tire/wheel/gear ratio settings... It should correct the dash too.

 

As I wrote earlier, if these settings were not correctly added. The Edge would not be giving an accurate reading.
