I did a similar test on a long strip of ice in my neighborhood. I thought it worked GREAT. The right rear wheel (the one on ice) would just start to slip and then it stopped and I accelerated forward in a perfectly straight line. This was not from a standstill, rather from about 10mph. I was VERY impressed with the performance... Drove the right side onto the ice, punched the gas, and then just got a big grin...Batman229 said:Has anybody else done tests like this?

yeah, i think this VDC stuff seems like a bit of marketing "bull," but the Titan's still an excellent 4x4 truck platform to build on. like i need a computer to remind me that we're slipping: my arse can feel that well enough.Batman229 said:Has anybody else done tests like this?

Was this test done in 2WD or 4WD?kentd said:Ok, I'm going to say that this 'auto-brake limited slip' does NOT work.
I found a parking lot, with a long, straight strip of ice.
This allowed me to place one rear tire on the ice, and one on the asphalt,
and try to accelerate.
The end result?
With VDC on, the tire would start to slip, then the 'slip' dash light would flash, and engine power would be reduced until traction was regained.
With VDC off, I could smoke the ice tire for well over 10 seconds,
or until I got the ice tire back onto the asphalt.
(the ice patch was about 75' long)
While doing the tests, the truck woulo only move forward at about 5mph.
I don't see this as any significant indicator that the 'limited slip' works.
Someone please tell me that I'm wrong.
I am wondering if VDC is only active in 2WD mode, and ABLS is only active in 4WD mode. The "limited slip" effect would come from the ABLS (i.e. traction control), and not from the VDC (i.e. stability control), which may explain your poor results in 2WD.kentd said:The test that I posted about was in 2WD.
When I tried the same test in 4WD, the acceleration was great, but it was difficult to distinguish where the extra traction was coming from.
