Firstly, Hi.

this is my first post, but a question thats been on my mind for a long time.
(only just been introduced to the website - thanks Shropshirelad) and what a great website.

anyhow back to the big question, if anyone has noticed the comment 'Unique engine tune' for varying fuel quality in the Land Rover literature do they know what it actually means?

is it an ECU mod, or other things?

Hi and welcome. Must admit never seen that comment. Where did you spot it

Hi Caterhan

First of all welcome aboard.

As far as I know the Duratorq motor has been modified to use a wide range of diesel quality (sulphur content).
That should involve the ECU programming but also should consider modifications in the inyection system and other components to reduce the SO2 emmission levels (part of the current problems I believe).

Something similar appears in the LR UK webpage

I have spoken to Land Rover and the unique engine tune they mention in the 2007 brochure I understand is intended for exports to parts of the world where varying fuel qualities might be encountered.

The reason for not offering it here is due to not complying with emissions.

It would seem they won't tell you want it involves, or offer it as an after market modification either?

Me thinks Biodiesel would work nicely on it.

Caterham

I've already told you that my dealer said the engine had been developed to run on bio.....

I know but Land Rover won't tell you that. A 'mate' of mine is running circa 30% bio (home made I believe) and up till has seen no difference.

I once drive a Def. 2007 with circa 70% bio and I'm sure it was pinking (but wouldn't put money on it).

Does anyone on here know of anyone who's running on Bio diesel .......(shut up Shropshirelad)

Ive asked this (at a selection of levels)

Apparently it does different maps (such as low has a different map) etc etc

Ive also been told (not by the designers) that it wont run on bio - the manual actually says this aswell

I'm told by a reliable source that the only reason that LR say you shouldn't run on bio-fuels is that the factory haven't done sufficient test mileage to state catagorically that they are OK.

I've been told that one of the dealerships is running a transit tdci on bio as a test vehicle and like I said I know someone running circa 30% bio (althought low mileage) with no problems to date.

off at a slight tangent the same mate has a 1.6 common rail Citreon Picasso (same engine as the focus 1.6 tdci) and has run 100% for the last 6-7ooo miles with no problems ! ?

The export markets get what is called an "EU2" tune (as opposed to the "EU4" tune sold in the UK/Europe) it is supposed to be more tolerant of the brown sludge that is sold in far flung parts of the world under the name "diesel". Time will tell...!

I have no idea what the actual differences are on the engine though.

EU2 runs a part cat instead of a full cat, and some mapping differences.

The rest of the engine is the same from what ive seen of it.

sold the cat bit (I'm not bothered about that - I'd like to drop it all together).

the mapping bit does interest me. could this make the difference between fuel igniting prematurely or not. If it were a petrol engine I guess it would be called pinking and you'd advance / retard the timing, but on a diesel?

I've been told (and this is purely out of interest ) that running the puma defender engine on biodiesel makes it prematurely combust and hence pink

can this be so?

I dont know anyone who has ran a puma on boi.

Dropping the car al together is no problem, which is why i have the decats made after my prototype was a sucsess.

someone must know for sure if the eu2 is simply a case of cat removal and mapping?

are the piezzo injectors too fragile for rough fuel / do they replace them too?
