I haven't found any specific information on how to interface and reprogram the on board center console trip/MPG information in my 2005 OBXT. I have 740cc injectors and all of the fuel related calculations now read incorrectly. After logging calculated vs actual, I have found that the on board calculator reads consistently at 1.48x(Actual).

I would appreciate any information on: 1) how to physically interface with the system; 2) how to modify the multiplication data to an accurate ratio.

Thanks for any help/info
