Speedometer error?
I am back with my misreading speedometer. I have checked reading by both GPS and measuring with a stopwatch, and result is identical. Speedometer is out 9,5 % across the board!
What this means is that it shows 9,5% to much all the time! If I understand it correctly it is not just speed but also distance that will be wrong. When I have driven 10.000 miles, car will show I have driven 10.950 miles, right?
Anyone have any idea if I can have it fixed?
Can I just to a GM rep and have them calibrate it? If so, will it just change speedo, or will it effect any programing made by my Powerloader?
Thanks in advance!

Re: Speedometer error? (6699)
Are your rear tires not the stock heigth? That is the only thing that can alter the speedo on a C5.
If you are Powerloaded, then I would contact them about this problem.

Re: Speedometer error? (6699)
One thing I observed while investigating this issue relative to LS1-Edit was a pro tune that had the output shaft speed scaling constant correct but did not have the gear scaling constants correct. Needless to say I was surprised they had managed to get the hard one and miss the easy one.
