2006 Crown Victoria P71 Speedometer calibration after 3.27 to 4.10 final drive change
Vehicle: 2006 Crown Victoria P71
Issue: Speedometer calibration after 3.27 to 4.10 final drive change
VCM Editor Version: 3.6.26
For Attempt #1 I changed the following
* Final Drive Ratio
* From: 3.27
* To: 4.10
For Attempt #2 I changed the above and the following
* VSS Tire Revs per
* From: 767.00
* To: 758.00
Each setting change did not alter the speedometer being reported via OBD or
on the instrument cluster itself.
I've tried a couple of variations on this, to no avail. ( Apart from drastically changing the VSS Tire Revs Per Mile )
Is there something I'm missing here?
For what it's worth the tire size I'm currently running is 225/60R16
Any input on this issue would be appreciated. Thanks!

So I was able to figure out the issue.
In Speedo->Calibration I was only seeing "Gear Ratio & Tire Size" as well as "Sensor Calibration"
In this post: https://www.hptuners.com/forum/showt...ight=use%20vid
It mentions "Use VID" to be set from Enabled to Disabled. However I did not see this in my menu.
I was able to solve this problem via Edit>View>Advanced in the top menubar.
TLDR: Turn off basic mode in the menu and search the forums thoroughly.
