Shaunyg88 Posted July 14, 2020 Share Posted July 14, 2020 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 Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted July 14, 2020 Share Posted July 14, 2020 You need to change the one in the VID block as well. This assumes that the VID block is enabled, if it is disabled you need to change the ratio under VID Block Calibration Overrides. If you use the navigator search it is quite easy to find the others.
