Hey guys, I was wondering if someone could tell me how to adjust the speedo on my 2001 mustng gt for 4.10 gears. All the changes got erased from my car and it's been such a long time since i adjusted the speedo that I can't really remember what to do. I have a Diablosport predator tuner by the way. Any info would be greatly appreciated.

 

You do it thru the tuner. You have to find the programmable parameters setting and set the rear ratio from 3.27 to 4.10

 

RTFM, download it here...

 

Hey guys, thanks for responding but I looked it up through another source and fixed it a day or so ago. Like I said thanks for the info.
