Hi I have purchased the OBD2 and Forscan, I have tried making changes to the pcm in my Ranger. After following the instructions and writing new values to the system they save but there seems to be no change to the dash readouts. I've put in a long range fuel tank and changed the litres from 80 to 140 which has been saved but the dash DTE still remains the same. I also need to change the tire circumference to a larger size and can also do that and the value saves but now I'm concerned about the speedo accuracy. Can anyone please advise.
