C5 Audi Allroad + TDI BHW + 2.5tdi Allroad 6 speed manual transmission

Gear ratios

Final drive: 35:8= 4.375
1st gear: 30:8= 3.750
2nd gear: 35:17= 2.059
3rd gear: 33:25= 1.320
4th gear: 28:30= 0.933
5th gear: 27:37= 0.730
6th gear: 24:40= 0.60
Reverse: 38:11= 3.455

From what I found the gear ratios we need to enter in the BIN file are 16bit decimal number we get by multiplaying the final drive by the corresponding gear x100.

Ex:
1st: 4.375 (final drive)x3.750 (1st)x 100=1640,625 Value in Bin file -> 01641 would be the value we put in the BIN file for 1st gear.
2nd: 4.375x 2.059x100=900.8125 Value in Bin file ->00901
3rd: 4.375x1.320x100=577.5 Value in Bin file -> 00578
4th: 4.375x0.933x100=406.875 Value in Bin file ->00407
5th: 4.375x0.730x100=319.375 Value in Bin file -> 00319
6th: 4.375x0.60x100=262.5 Value in Bin file -> 00263
R: 4.375x3.455x100=1511.5625 Value in Bin file -> 01512


How do we calculate the upper/lower limit for the V/N tolerance?
