What is everyone's experience with the H2's TCS? I have not been impressed, really. Has anyone found it to be beneficial in any situations/circumstances? The Hummer propeganda makes it sound like it is almost a replacement for lockers, but I have not found this to be anywhere near the case. This is an excerpt from something I saved. I think it is from Tustin's site:
I did some playing around with it the other day, and it did not even come close to this claim. I blocked one front and one rear so they were just off the ground, and then put it in drive. Almost immediately the "traction active" notice came on the display, and you could hear the sytem activate, and even feel it braking the two wheels, but it never stopped them from spinning, and you could feel that the truck never even seem to be trying to drive off the blocks. Now, this was on flat concrete, and the blocks were not all that solid. In fact, at the conclusion of the test I put it in low-lock and locked the rear diff, and when I put it in drive then it just drove right off at an idle. Didn't even have to give it any throttle. Also did it with whole rear raised and just in 4-high. Again, no help. Once I put it in high-lock, it drove off the block easily. In both of these situations I only had 2 wheels with "virtually no traction," yet the truck did not move.
In "real world" driving, I have not noticed it being any help. In fact, it usually is a hinderance. On hill climbs in sand dunes, as soon as the system comes on it is just like taking your foot off the gas. Same thing in deep snow, as soon as it comes on you just bog right down.
I have heard you guys with H3s say that it works well with your trucks, so I wonder if there is something different, or if something is not working right with mine?
Anyway, I was just curious if anyone else has had a different experience with it. I am kind of planning when I have a custom tune made for my truck to have him disable the TCS.
The Single Wheel traction control system provides additional capability under certain operating conditions. The system detects a slipping wheel and applies brake pressure to it to slow it down, transferring torque across the differential to provide traction for the wheel on the opposite side. The system senses any slipping wheels and applies the brakes to them individually, while the driveline and differentials transfer torque to the wheel with the high traction for added traction. A driver could have as many as three wheels on a slippery surface with virtually no traction and still get enough torque out of the fourth wheel to propel the truck up a 10 percent grade.
