My torque split controller arrived yesterday & I fitted it this morning.
Very good mod! I think the best way to describe the feel is to describe how the car handles with stock torque split controls, and then overlay the new response.
My car is typically pretty tail happy during throttle roll-on in corners. (Like every R32 I expect!) Typical behaviour in the dry is for the tail to kick out in a progressive, controlled manner. It doesn't kick out as far as my Mustang would have in similar conditions as the front wheels do get some torque allocated as wheel slip increases, but it's definately out there. Very confidence inspiring, but somewhat sideways. The tail kicks out a lot more a lower speed corners as torque at the wheels is substantially higher than on fast sweepers.
There are a few conditions where understeer happens. The one I can describe for you is a slight downhill, nice pavement, 270 degree corner, decreasing radius, and flatter than most. I don't typically carry much speed into this corner (common sense?), but when I can see the coast is clear I'll step into it fairly hard. As the radius tightens up I'm either coasting or rolling throttle on, depending on speed. The car will understeer slightly in either condition.
There's a 90 degree increasing radius RH corner I like as well. Stepping into it on this one in 3rd gear is a good way to kick the tail out from about 100 to 130 km/hr. It comes back in as you run out of torque, but a comfortable exit speed is around 150 km/hr. This was the first real test for my new TSC. It's adjustable from 0 to 10. 0 being no attenuation of the lateral accellerometer, and 10 being full annenuation. The chap who builds them suggested 6 for dry conditions, so I started at 6.
I accellerated into the fast sweeper rolling throttle on enough to kick the tail out under normal circumstances. Nothing. Except solid accelleration! I'm not sure what would happen if I gave it WOT without the stock setup, but I think the tail would just hang out a bit further. At '6' on the TSC, the car stayed planted no matter what I did. (I now understand the warning in the installation instructions. Something like, 'Caution, this device does NOT make it impossible to crash your car.') Anyhow, WOT to the top of 3rd gear and I couldn't wipe the grin off my face. Not that kicking the tail out isn't fun, it's just that much MORE fun to be able to 'program' the car's response to throttle in the corners!
I gave it a good workout on some slower corners and the car remained neutral at 2nd gear cornering traction limits as well. Power understeer only became evident on the decreasing radius 270 degree decreasing radius, and that might have been because I carried a fair bit more speed into the tight part of the corner! :P
Apparently '9' is a good setting for wet track conditions.
I'm pretty impressed so far!
Cheers,
