I won't say correct because a fact is by definition correct. An incorrect fact is an oxymoron.

...SNIP...

A td5 has idle revs of 750. The feature definitely only works on low 1st too. Idle in 1st low is at the same 759 rpm.

Ian.

I deliberately used the word 'Approx'... The TD5 & TDCi have different idle speeds and on top of that, the TDCi increases the idle speed in 1st low.

BTW - My favourite 'Oxymoron' is "US Military Intelligence".

I was watching a YouTube video with Defender and cruiser 70 comparison. They made a point that the antistall feature actually gives the defender less control on steep downhill in low range causing it to run faster. Is this true? BTW am picking up my new 110 in 4 weeks.

I think it is. I've only ever taken james offroad once but I found myself having to step on the clutch at times to stop from going too fast.. but then i was in high. that might have had something to do with it lol

Can't say I've ever come across this... I've been down angles steep enough to need resting your weight on the steering with arms outstretched and I've never had it overrun.

The golden rules of steep down hills are:

Low Range Differential Locked (no compromise on this!)

1. No clutch
2. NO CLUTCH!!!
3. If in doubt step on the accelerator to regain traction and steering
4. Use the foot brake sparingly if you've lost your planned line...

The Puma's firsts low is so slow (when not interfered with clutch use!) that there is physically no way of not having control.

Any control loss would usually be attributed to the driver starting to panic and not trusting his car...

Cheers,

Lou

No, that's utter twaddle...

If the ECU detects the car is in Low-1st, the idle speed is deliberately raised to 1000rpm. This is called the 'Idle Jack' and nothing to do with 'Anti-Stall'. As stated before ALL EFi systems have an element of anti-stall...

The reason for this is that 1st-Low is soooo low, it actually increased the risk of the car sliding on a very steep slope. The idle speed is raised a touch, to help reduce this risk.

I have found on rocky ground some times the car won't go slow enough and it's "jerky". Would disabling the anti stall cure this?

There are a few clips on YouTube showing what the anti stall is capable of......here's just one of them........

It works simply on revs....has nothing to do with what gear it's in on the td5.....or whether its in high or low range..........
