Hello all -

How do you guys with 19 or 20's correct the MPH on the cluster to correct it out.

Right now I am ( on the cluster ) going 3 MPH faster than a GPS ( tried iphone/android note2) and the phones gps are exact on both but car is showing its going faster (speedo).

Any ways to correct this ?

I have Osiris/Cipher and I can do my own ROM uploads - but there doesn't seem or I cannot find it a setting for MPH correction or calibration...

 

Just change the speedo gear in the tranny.....oh, never mind, I just had a flashback to the '70s.

LOL - the good ol days huh - that was also a pain - getting the right tooth to match the tire size... LMAO
Good times -

Still need this one though -

 

See if this will work for you
