Had the Monaro.. ohh sorry Ro.. a few weeks now, had the wheels refurbished [ thanks for the advice guys ], de badged the Vauxhall bits and generally getting the car cleaned up to my liking, this time of year the roads as we all know are almost constantly wet so only been out a few times but what I have found is that the traction control seems none existent if I give it a bit of boot the tyres just light up with no warning TC lights or noticable intervention of the TC, I have read on here that the traction controls not the most sophisticated system but surely it must be better than what I have described ?....have also turned it off with no noticable differance either

If it's working the accelerator pedal will be pulled away from your foot downwards (a bit like the feeling of ABS), if not then I would suggest it's not working.

To test mine, i found a nice wet piece of road....and floored the throttle hard. Tyres lit up for a brief moment then the revs dropped right down. Pretty poor, but it is there.

No thats not happening, will give it a little more testing...good fun !...and then put it on the list of warranty jobs....getting them done may be story on its own I think...not seen the problem on the forum before ?

Mine don't pull the trhottle pedal away from my foot. Surely that's bloody dangerous!

that's how it feels, i never use it at all, tried it once and thought it was more dangerous than learning to control the car. tried it on an icy road on then off and since then as soon as the engine is running I turn it off.

Someone else may correct me but as far as I know, the ro has an electronic throttle with analogue input. As soon as the computer senses loss of traction to rear wheels, it cuts or reduces fuel input and the display beeps and flashes. It is slow to respond though. Probably came off a 1.8 vectra.

How slow to respond ? I went from 1st to 2nd with the wheels spinning lifted off after approx 5 secs.

when they find the fault, tell me, it'll save me turning it off because I hate it when i forget to turn it off.

When I did my test I mashed the pedal into the floor. Took about 2 or 3 seconds before it engaged. It is proper shite though. Almost destroyed the car a few months back when i lost control and the TC didn't even notice. For your own peace of mind it might be worth getting it checked but almost all will agree it isn't much use.

This is a feature of 04 and earlier cars only. Fully electronic after that.

Mine is quite instant and now matter what you do with the right foot it will not speed up until all is fine, does feel wierd but does work.

Crikey! Might get mine checked as well then!

The TC on my 04 CV8 is very sensitive. Even a slightly brisk launch, or sudden low-gear acceleration on a dry surface in anything but a straight line will activate the system. It has never kicked in on a slippery surface, but I put that down to adjusting my driving to suit.

The TC still switches itself off occasionally, but at least the dash display tells me it's happened.

both TC systems effectively work by backing off the throttle.

the electronic throttle can be backed off by the computer without you knowing ( apart from the reduced power)

the previous system, if it's the one I think it is, has a long loop of the throttle cable running around a cam. When TC intervention occurs, the cam is moved, introducing a large amount of "extra" throttle cable into the system, both backing off the actual throttle plate and giving the impression that the pedal is moving away from you.

That makes sense, I have the electronic throttle version from what has been said I am pretty sure I have a problem with the TC as the revs feel like they will go through the roof too, ......Are the rev limiter and TC linked, I dont really like the idea of testing the rev limiter to see if it works [even stationary]

Your rev limiter WILL work. No need to test it. Unless someone has adjusted it to a different level.

Cheers....car is standard so I doubt it has been altered.

it's easy to tll - if you can see a throttle cable hangine off then end of the throttle body, it'll be the earlier system.
