Does anyone know the % for ACD. No guessing

tarmac = 50/50 F/R

gravel = ?/? F/R

snow = ?/? F/R

 

i dont think its a percent. it just locks and unlocks the diff based on speed and steering angle. from what i understand you cannot get more than 50% to the rear.
but, of course, this is just from "hearsay" so take it with a grain of salt. sorry for not following your rules

 

if you change the ACD computer....u will get more than 50% to the rear

 

"active" ACD differential varies its locking characteristic according to inputs from accelerometers and other sensors.

One typical "active" strategy it applies is to stiffen its locking when the car starts negotiating a corner (the braking phase) allowing for maximum deceleration, loosen the locking to negotiate the turn-in phase, stiffen a bit mid-corner allowing more torque to the rear in order to turn more easily and stiffen even more while exiting the corner to provide the maximum grip and acceleration.

 

Oh....and think of locking a diff as running wheels of either side of the axle at the same speed

 

it's basically a viscosity slip differential that works off of the center differential that's controlled by the computer. Fansy LSD is what I think it is.
