Correct Gear Ratio for Dyno

Supposely the appropiate gear ratio to dyno is the closest to 1:1.

Manual gear ratios - I/II 4.32/2.46 :1
Manual gear ratios - III/IV 1.66/1.23 :1
Manual gear ratios - V/VI/R 1.00/0.85/3.94 :1
Manual gear ratios - Final drive ratio 3.23 :1

In the E90, that would make fifth gear the appropiate gear ratio. And so many people getting crazy numbers dynoing in 3rd and 4th... shame...shame..
