This information are based on my knowing for the PSX copy. It compare the information between the PC english manual

PSX pal german copy, the manual has no information for any tuning options !

Categories for PSX are 2, arcade and simulation (tuning).

PSX Tuning:

style: arcade / simulation works only on Simulation !

(arcade is different to simulation mode, driving differences)

01: Engine Tuning - low end, stock, high end game information: Set the engine tuning to 'high end' for more top-end power on fast tracks, or set to 'low end' for low RPM power appropriate on slow, twisting courses.

PC Manual information: Tune toward the low end for faster acceleration or to the high end for more top speed.

02: Brake Balance - front, stock, rear game information: Move brake balance towards the front for more predictable braking. Set the balance towards the rear to induce slides in turns through wheel lock up.

PC Manual information: Tuning to the front creates an understeering car by transferring weight to the rear during braking. Tune to the rear for an oversteering car.

03: Steering Speed - slow, stock, quick game information: Slower steering results in wider but more stable turns, whereas quicker steering permits sharper turns with a possible compromise in handling predictability.

PC Manual information: Set this option slower for more gradual tuning or quicker for fast steering.

04: Gear Ratios - high, stock, low game information: Higher gear ratios will tend to increase acceleration but may lower top speeds. Lower gear ratios will tend to slow acceleration for improved top speed.

PC Manual information: High gear ratios let your car climb through the gears quickly, spending less time in the slower gears. Low gear ratios trade sluggish starts for top speed.

05: Suspension Stiffness - soft, stock, stiff game information: A stiffer suspension will provide more stable cornering. Softer settings can allow drifting the tail around corners for sharper turn-in, but with less precision.

PC Manual information: A car with a soft suspension rolls into the turns. A car with a stiff suspension fights the road but gives you a better feel for it.

06: Aerodynamics - low, stock, high game information: Low drag allows for higher speeds but without as much grip at top speed. High downforce improves grip at high speeds at the sacrifice of a faster top speed.

PC Manual information: Tune higher for more downforce, increasing handling but reducing speed, or lower for less wind resistance.

07: Tires - rain, stock, race game information: Select race tires for the best grip in dry weather. Rain tires give the best grip in rain or snow and stock tires are the best for mixed conditions.

PC Manual information: Rain tires grip the road under wet conditions. Racing tires have smooth surfaces that stick to dry roads.

Driving Assists

PC Manual Driving Assists Menu (manual, only in Single Race and Hot Pursuit mode, Ghost Car different option)

01: Braking With braking assist ON, if you are driving too fast to negotiate a turn, the computer slows your car.

02: Collision Recovery Set collision recovery ON for faster accident recovery.

03: Traction Traction assist keeps your tires from spinning when you generate excessive torque. This enables the car to hug the road for faster cornering and quicker starts.

04: Best Line Pylons mark the fastest racing line around the track. Try to stay between the pylons, then check your success rate at the end of the race.

05: Navigator When ON, colour-coded arrows and the NFS3 announcer help you navigate the turns.

06: Pursuit Available in Hot Pursuit mode only. When ON, as soon as you make a bust, your car teleports up to the leader, so you have a good chance of busting him too.

Extra note: Ghost car PC, save ghost car replay file and send it to a friend and he can race with your ghost car.
