I tryed to install the 1845 Flashpaq on my 2014 Ford with 6.7 diesel and would not save factor setting?
The unit said I did not have factor tune? No modification to truck only stock?
one recall by Ford to adjust the DEF (diesel exhaust fluid required).
Had the computer reset by Ford to verify stock and retried Flashpaq... same answer not a stock setting would not safe setting?
