Are these not working yet with build 85? I'm using the 370z gear file as a guide, but what is there is commented out and not working if un-commented out, commented in? LOL ;P I have a couple of sets of gear ratios, some vary the rear end ratio. With my upgrade.ini I was setting what is being used. My bit for gearbox switching seems to be ignored. Are upgrades also not working? Is there a different way the sets are being handled? Lastly, I think you may have missed a grouping for a ratio for the Hewland box. Supposedly some "TGT" ratios are available for 2nd. The only reference to TGT I could find were the 2.923 and 2.200. If I am understanding the new format correctly, to add the 2.923 as available to 2nd the gear ini could read: Code: RatioGroup=(0,1) ratio=(12, 37) // 0: 3.083 RatioGroup=(0,2) ratio=(13, 38) // 1: 2.923 RatioGroup=(0,1) ratio=(13, 37) // 2: 2.846 ...
