Speed Adjust

[idk]

Does one need to run the 12 minute adaption tune when changing the speed adjust? My speedo is off about 3-4 MPH at a -5.1. It came with the Tripp Tune Map, so I left it as it was.
I have a couple of GPS apps and found the difference. I'd like the odometer to be correct, too.
Thanks!!

You can have either the speedometer or the odometer correct - but not both.


Or you could have them both incorrect if you want.

$ell i just don't want a ticket by pushing the limit. 72 miles per hour here in Oklahoma they will not $uck with you. Anything over depends on the trooper.

Did the tune ecu thing and adjusted to 0. Funny thing is now my TPS is green and gas gauge bar is working again. Go figure.

Or fit a GPS speedo and have both correct (except in tunnels).
I have a couple of clocks that are spot on time twice a day.
