This is for 4 wheel drive cars only. LSD is most useful on a 4wd because it is on all four wheels.

Initial determines how quickly the lock comes in when power is applied to the axles.

Acceleration determines the balance of axle lock when power is applied. Too high a setting on the rear will induce over steer exiting high-speed corners. Too high on the front will induce understeer exiting the same corners.

Deceleration adjustment will ensure both drive-axles resist rotation equally. It is most effective in controlling high torque, rear wheel drive cars when entering a tight corner from high speed.


entering low-speed corners:
---------------------------------------
Problem: Underseer
Solution:
Front Initial: low
Front Accel: --
Front Decel: low
Rear Initial: --
Rear Accel: --
Rear Decel: --


Problem: Oversteer
Solution:
NO SOLUTION: can not be fixed with LSD.
You need to set up other parts.
