Hi everyone,

I recently upgraded my rims/wheels. I found a very noticeable difference in gas mileage. I knew it would change, but I thought it would be close to negligible. I'm tryin to see how inaccurate my speedometer is now. I was wondering if the speedomoter on the GPS would show accurate if it was connected to the VSS or would it just show whats going on my dash?

Thanks,

Shak

I don't have the VSS wire hooked up to my HU and the speed in the vehicle dynamics is still accurate to within ~(about)1mph.
