Just wanted to ask if anyone else is having issues adjusting their speedometer with the Superchips programmer?

It did correct it "to a point" but now it seems that no matter how much I decrease the tire size the speedometer stays the same.

I have 35 KM2s and I first set it at 34.5". This brought the speedometer much closer to actual, but now read slightly faster than I was actually going. So now I have tried 34.25", 34" and 33.75" and the speedometer never seems to change!

Any sugguestions or similar experiences?

 

I have not had that problem. But if your speedo is reading high you are going the wrong way with the tire size. I run 35" KM2s and I set my flashpaq up for 34.25".

 

I had to fiddle with mine a few times to get it right. I think I am set for 33.5" tires on my 35s......
