What do they mean on point 16 by "If you find the gearing slightly long (tall) on your pre- facelift 2002-2004car"

Prob the best answer I can find.
Short gearing: You rotate the throttle or press the accelerator by 20% and the rpm(rotations per minute) reach their max capacity, after which you have to shift to an upper gear if you want to keep accelerating.
Tall gearing: Means you will be able to take the above percentage to a higher level. Eg. 40% without being required to upshift the gear.
Tall gearing is helpful in stop and go traffic because you have to shift gears to a lesser extent as compared to a short gearing vehicle.
Hope this helps...
I actually find my 1st gear on my 2006 R53 short and would rather it be a bit taller before I'm into 2nd.
Short or tall gearing refers to gear rations.
At certain rpm lets say 2000rpm the car will go at different speeds in different gears. Not only that two cars will go at different speeds at 2000rpm in their top gears.
So if you have taller 5th gear in car A than car B you will go faster at 2000rpm, which means more relaxed cruising for the engine.
Short gearing means that engine has to rev at a higher speed to get the same actual speed.
So in a shorter geared car you will get better acceleration but lower mileage because your engine is running at a high speed.
For example esteem as a very tall 2nd gear. At redline the second gear can cross 100kmph. At the same rpm in other cars the seond peaks out at around 80-90kmph at the same rpm.
in addition, tall gearing may also be referred to the gear ratios: the step up from 1-2-3-4-5 should be smooth, as there should not be any un-necessary revving up in the prev gear to match the 'comfortable' speed of the next gear.
fuel efficiency is the main reason to provide tall gearing.
