I changed the speedo gear in the trans when I changed to 275/60/15 tires. Mph on the powerlogger is accurate as well as the speedometer

A 215-65 vs a 275-60 it is 93% the factory tire being 1 on the power logger (not sure )it is .93 reduction from the 275
factory tire is 26 and 275 is 27.99

It is really .929
Vehical speed scale would =.929
Never tryed this let me know if it works

Thanks to all. But I believe you change the 1 in vehicle speed to 1.071. I changed my ini file and my logs are now closer. Thanks again
