Question For Parts/Service or Anyone I The Field.
Should/Could I Getmy Comptuer Reflashed In My 2005 Dodge Ram 4.7 4x4. I Have 4.56's W/ 285/70/17's and My Spedo Is So Far Outta The Arc. 46MPG = 60MPH. If It Wasnt For MY GPS I'd Be Far In With The Law.
I Currently Have An Accuspeed But I Cannot Get It To Work Properly. And There Is No Programmers Aval. For My 4.7... I Don't Want My Warranty Void, Will They Reprogram It - DO You Think It Wold Void My Wrranty?
I Need To Get Something Done... It's Gettig Old.

RE: Speed-o-meter
I would get it reprogrammed. It can be done by tire size or tire revolutions per mile in a 2005. Reflashing the computer will not fix this. They have to go in and reprogram the pinion factor. VERY easy fix. Takes about 10 minutes. Revs per mile is more accurate. They might charge you, but if you do not get it done and you have any warranty issues, this is their out. If they do not know how to do the revs per mile, call me and I can tell you how to do it......DAVID
