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

Hi Mate slightly off topic but how did the xr6t and the zf overall respond to the 3.23 gears. id imagine its a very good gear choice only 1st gear being very tall.

Yes it can. You can still use a spark hole or a rev limiter (for a manual).

Obviously there is no turbo to spool so the system will be a lot simpler. In the case of the 5.0 supercharged you probably actually want it to reduce power so that you don't turn the tyres. All comes down to the use case and the goal as to what the tuner will do.

beauty thanks Roland yeah i was basically asking for drag strip situations. Should help heaps having finer control.
