Anti-stall question...

[adzee]

I am sorry if this has been asked before but I use ForrumRunner and search is horrific!

Just wondering what year or model anti-stall was put in, and is it standard on all from what year?

I'm looking for a defender shortly, and want to know a bit more, how to activate/test it.

Thanks for your help.

It is only on the puma engine models - 2007 onwards & will only operate in low range.This happens automatically.

Thought so! Looks like I won't be getting this then. I think...

Fingers crossed a good inexpensive one comes up.

It actually works in high range as well, great for hill starts

A late model TD5 has a type of anti stall. It's only on first low and it's not massively sophisticated, but if you let your foot off the cluth slowly and give no revs it will set off and fuel itself to tackle some half decent lumps and bumps.

Definitely works in high as well as low range. I live on a hill and it's wonderful for parallel parking.

Bad for getting in a different vehicle though...I have to make sure I use the handbrake on hill starts!

.. just how a 1980s 4BD1 functions, except it seems to work in high range as well !

Come on guys, get your facts correct!

Anti-stall... A quick potted history.

In theory every single vehicle fitted with an electronic fuel injection system has 'Anti-Stall'.

TD5 has anti-stall but the parameters were tweaked and turned into a 'feature' for the TDCi (Puma) engined cars.

How does it work?

Simply, the ECU is constantly monitoring the engine speed and if the idle speed drops below approx 800rpm, it'll give it a little give it a little more throttle to get the engine speed back up. So, when you get the clutch up to the 'bite' point, the engine revs will naturally drop so the ECU (anti-stall) will compensate.

Anti-stall will work in any gear, Hi or Low range.

However, don't get confused with the "Idle Jack"... This increases the idle speed to 1000rpm when in 1st Low.

Get your facts straight, buddy. .

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

Simply, the ECU is constantly monitoring the engine speed and if the idle speed drops below approx 800rpm, it'll give it a little give it a little more throttle to get the engine speed back up. So, when you get the clutch up to the 'bite' point, the engine revs will naturally drop so the ECU (anti-stall) will compensate.

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.

Just got a new map from Jose for my TD5 the idle speed was raised up to 800RPM and changed fuelling.
Its fantastic not sure if it suppose to be a feature or not but in second high you can just let the clutch out without touching the throttle and it just idles off.
Very impressed
