Not sure if this is allowed to be asked here,but I figured I would give it a shot.I was wondering if there is free/cheap software available to correct digital odometers,along with the schematic to build the OBDII adapter.I know there are kits available for many thousands of dollars,but was just curious to how these things worked,FOR EXPEREMENTIAL USE ONLY.I just like to play with these things,no intent on hurting anyone,thanks for the help... :lol:
