Difference (percentage) between 4.10s and 4.88s.

I'm now running 285s and 4.88s. Before, I was running 285s and 4.10s. That meant a difference of 7.3%, or, my speedometer was reading 7.3% slower than actual. Can someone help me calculate the new difference, please?

Thank you!

Your conversion factor for distance is 4.10/4.88 which is about 0.84. When your odometer says you have gone 100 miles, you have actually gone 84.

No - it read 7.3% slower than before - don't assume that it was accurate from the factory. Mine was actually MORE accurate with the 33's than it was with the 31's per the GPS...

Anyways - you can calculate 'til you're blue in the face, but the only way to REALLY know if your speedo is right is either time over distance or compared to GPS.
