Hello everyone!
I am working on some things at my brothers place down here in Ethridge, TN, it's about an hour and a half south west of Nashville.
We changed the rear axle assembly in his Suburban, changing his gear from a 2.50 something to a 3.73.
His speedometer is way off, as well as his odometer.

Is there anyone in the area that could plug it in and help us with the Speedometer calibration.
I just found out that my cables I brought down here with me (I'm from Michigan) will not interface with OBDII, and the cables I need for my tuner (TunerCat) I would have to order... we're leaving to head back home Fri. morning... So I wouldn't get it in time to help him.

Would be great if there was someone around that could help!

Smitty
