yes

with the scan guage does it fix the odo

Fix, no. It just gives you a corrected readout as to the speed your actually doing plus many other parameters, i.e,; water temp, rpm, MAP, Load, MPG, things like that plus engine fault codes and reset.

Only thing I want to be able to do is recalibrate for tire size.

With my oversize tires, I just use a more "analog" method-- the Discount Tire website "Tire Calculator". It will show your projected travel speed at various MPH settings.

For example, my oversize tires (275/65R18) run about 5 MPH above my actual speedometer reading. So if the posted speed limit sign says 60 MPH, then I just put my speedometer needle on 55 MPH with no worries.

Uhhhhhh...

Math don't work that way Riff...

It's all about the %.

example: a .07% difference in tire size = these speedometer values...

55 = .07x55=3.85, so 55=58.85

60 = .07x60=4.20, so 60=64.2

65 = .07x65=4.55, so 65=69.55

and so on...

Haha, well I had to disassemble my gauges and needles to install intelli-glow needles, so last time I had the needles off, I had someone with a stock car drive 65mph next to me with cruise on and I matched their speed with cruise on and then I replaced the needle at 65 mph and then I had them speed up to 70 and then down to 60 and stayed with them and checked to make sure my speedo was close and done.

I know it is not a perfect fix, but it is nice to know that at around 60-70 mph the speedo reads true :-)
