Thread: 07 defender anti-stall

TD5s also have a similar feature!!!!

I had a go today in some sandhills. Not a proper test, just mucking around.

It doesn't seem to work in high range, because I just stalled it! But in low range it just keeps trying and trying and would have eventually dug a big hole under the wheels - feet off of all the pedals.

I aim to read the manual some time this week to see how it is supposed to work.

It really isn't an anti stall mechanism - Land Rover don't market it as one - it only happens on the Td5 because as you start to release the clutch, the revs fall slightly and because the accelerator isn't being pressed, its gets confused into thinking that for some reason the engine is stalling... and reacts to prevent this.

It only works if you release the clutch very slowly, which funnily enough all cars can do including my IIA and "granny's corolla" provided the clutch is released slowly enough.

Jump into your Td5 and just dump the clutch at idle - you will see no such feature exists.

Drove a new Defender at Riverside Oaks as part of the vehicle launch last week. The Defender just walked over several difficult obstacles on an off road course without any throttle. Pretty useful feature esp. over rough terrain where otherwise difficult to use the throttle smoothly.
I was impressed.

I also had a drive at Riverside Oaks last week and agree with 'alexander' - the vehicle performance is most impressive. First low, with feet flat on the floor and it walked through everything they had set up for it - moguls, descend and climb out of gully etc. However, it didn't like second low, although OK with a slight tickle of the accelerator.

I also went around the track in a Disco III and apart from a bit of minor underbelly scraping in a few places it also handled the track quite well.

The vehicle is also amasingly quiet and gets along on the black ribbon at a low 2000rpm at 100km/h.

Have posted some pics in my members gallery from the Riverside Oaks test track showing a little wheel lifting.

Wrong...

It is marketed as anti-stall and as correctly mentioned, there is a similar system on the TD5. One of the ways we teach people to use it is for hill starts, when off-road, without using the handbrake.

Contrary to popular belief, you can still stall the engine... After all, it's just anti-stall and not a re-write of the laws of physics!

The way it works is that the ECU monitors the engine idle speed and when it detects that it drops, it'll compensate by opening the throttle slightly. So... If you bring the clutch up gently to the bite point, the idle speed will adjust, bring it up a little more and eventually you'll be able to gently release the foot brake and the car will be held on the clutch. Bring up the engine revs and continue with your hill start.

Easy...

Hi,

it's a long story but does anyone know if it's possible to disable the anti stall on an 07 ?
