Hi all,
Customer has had the diff ratio changed in his 07 BF XR6 turbo with ZF 6speed to 3:23 from 2:73, to change the ratio in the PCM calibration do I just alter auF0394 or is there another area that needs changing?
I have changed the auF0394 value to 3:23 and when I checked for codes after the road test I have code P1934 vehicle speed signal, car drives okay.
Thanks Neil
