DTC Off

I've noticed no one has mentioned how the dtc affects the car in corners.
When you have everything set to standard and you go around a corner, the car won't let you accelerate until you reach the apex of a corner (I find this irritating as it does not encourage progressive driving)
When the dtc button is held down for 5 secs and all driver aids are turned off, then you can accelerate into a corner and come out even faster, loads of fun once you get the hang of it, especially on twisty roads!
Also there as others have said it is a lot easier to lose control, I once tried to turn left on a sharp corner in heavy rain, sport on dtc off, I ended up turning 270 degrees left instead of 90

It will let you accelerate if there's grip available to accelerate with. The angle of the car versus the steering input is only used to work out which direction you're *wanting* the car to go in, as long as the traction is available and the car isn't sensing any substantial slippage of the wheels, it will accelerate.
The car has no way of knowing if you're at the apex of a corner.

You may feel like you're going even faster, but carrying "too much" speed into a corner is rarely the fastest way round it.
Hmm I thought I read somewhere the Car had an accelerometer type of thing that could kinda tell, what you say does make sense tho, as going around sharper corners, traction control would be limiting the power to the wheels.Siftah said:

I know this all to well. My last car was a 400hp skyline and it taught me a few Things. This car has much less power but much more rewarding drive I think
Hotride said:
It does have a gyroscope (I believe, manual isn't handy at the moment) so that it knows the angle of the car, but it's using it to work out the line you're attempting to take rather than anything else.
If I'm understanding you correctly, a gyroscope would be overkill for that application anyway as all you really need is to know the steering input. It'd be fairly trivial to just kill engine power at any time the steering isn't straight - I should imagine that wouldn't be popular with most drivers though

I have a DTC related story I would like to share with you all:
I took my z4 to Southern Ireland the other week (when we got hit by that sudden downfall of snow!). We got stuck on the N9 - one of the main National roads into Dublin - after a MASSIVE sudden snowfall. Traffic came to a complete standstill for over 3 hours because lorries were having trouble getting up the hill ahead. Needless to say I was very doubtful of getting up but I had a passenger willing to push and no other option so I had to go for it. The police were at the scene and people were going up the hill one by one because it was so dangerous (this is a three lane dual carriageway). Now if you look in the handbook it recommends driving with DTC on (i.e. Yellow DTC light on dash) on icy/snowy hills for maximum traction - so I did as it says. I got about 50 yards (of roughly 3/4 mile) before coming to a standstill :-(
My passenger got out to push....another 50 yards or so before getting completely stuck in what was easily 7-8 inches of snow. Next thing I know 3 trick drivers have come to help my friend push (very nice of them!). We get about half way up the hill and get stuck once more. One of the truck drivers came to my window and told me to "turn your traction control off, put it in second and put your foot to the f****** floor!" I did as I was told, very wary that I wouldn't move an inch. I wa revving to around 3500 RPM (3.0 si) and obviously just spinning my rear wheels, the truck driver came back to my window and said "I told you to put your foot to the f****** floor!" so I did...7000 RPM later I'm going 100% sideways up the hill at around 15 mph! I had to leave my passenger to walk the hill for fear of getting stuck again - he'll understand.
Next thing, whilst ascending this dreaded hill sideways, I hear the distinctive double honk of a lorries horn, I look out of my drivers side window (where I've come from) and see a Jack-knifed lorry travelling in my direction at at least 30 mph! Needless to say I'm clenched as I watch his headlights pass by in my rear-view mirror....and then into my passenger window - PHEW! One of the scariest moments of my life!
Thought I'd share that with you all! For those of you that care my baby had to have 2 new rear tyres (very expensive) and had my friend (a very good mechanic) look over it. Thankfully there doesn't seem to be any damage :-D
