[diff ratio change/calibration]

Hi Roland,

Ive got a fg g6e turbo zf 6speed. std ratio is obviously 2.73.

ive put a different diff in it and the ratio is 3.07.

how do i cange the ratio correctly in the pcm so my dash is accurate.

it is currently out about 12-15 kms.

ive already changed the diff ratio under the axle sub heading, but it hasnt changed my speedo calibration.

is there another setting that needs to be changed.

 

thanks alot

Hi Guys,

Will it be safe to raise the standard boost which i believe is around 10psi mark in a fg, up to about 12-13 without changing any fuel/timing tables?

Thanks for that mate. Do you also have to disable closed loop o2 like in your how to guide?

Thanks for the reply roland. 

Could you add the tables that need to be modified? Or is it all apart of what's in your original post?

Hi Guys,

Sorry bit of a newbie question. With applying all the above settings, how do you then set your targeted boost setting??

Say i want to run 15 psi?
