RR vs X5 - same engines, different maps?

Hi all,

Done a bit of digging but cannot seem to find anything to confirm this either way. I was told by a mate that when the L322 was new out, BMW naturally wanted to knobble it slightly compared to their own X5, and as a result the RRs all had slightly detuned ECU maps compared to an X5 with the same engine.
Is there any truth in this? Some websites quote them both as producing 290BHP, but others say the BMW has 320.
If the maps are different, could it be because the heavier RR is tuned for more torque over the lighter more "sporty" X5? NW060

At about the time the L322 came out there was a voluntary agreement between manufacturers that they wouldn't go above 300BHP, hence the FF is quoted at just below that, in truth all that were tested were around 320bhp...

Just a case of them massaging the numbers... You can get them chipped which will give you another 20bhp or so but it will all be at the top end so not much use in everyday driving...

I'm going to have mine chipped soon as a mate has just become a dealer and they are sorting a map to make the most of the 105 octane that LPG is... Pete

Land-Rover used to detune previous BMW engines, because they were indeed more geared up for pulling heavy loads and off roading.
The X5 was never really intended for that, so it may well be true that X5's have more horse power, but less low down grunt. It's not really about them being nobbled, which is likely just bulls*** from someone who owns and X5 and want's to make out he has a better car, but more about being suited to their intended purpose.

It's also unlikely BMW would want to place restrictions on someone buying their engines, after all they want to keep selling their engines, they make money on them the same as they do cars. In fact when they sold off the Rover group one of the parts they kept hold of for another 4 years was Powertrain Ltd, who built the K-series and L-Series engines. The only reason Land-Rover went to their own power units is it's cheaper to build them in house when they already have a perfectly suitable unit in production.
The switched Diesel suppliers, because their then parent had an agreement with PSA to co-develop diesel technology. PSA are renown for their HDi technology, which next to VW's TDI are the best small diesel engines out there.

That was the so-called "gentleman's agreement" in Japan that led to nothing domestically-produced being advertised as having more than 276bhp (even if it did).

The only time an l322 will get 75mpg is when it's owner uses the heavily used yellow card on it 😄😄😄 FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

That's not cheap, requires the fitment of an electric motor and a genset in the boot lol FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Well i think the 2.7 V6 was largely PSA anyway, intended for their Citroen C6. I think the 3ltr upgrade was at the behest of JLR. Because the C6 is a rare beast indeed.

The V8 was basically ford/JLR led.

However PSA do seem to have a history of releasing some engines too early. The 2.2 DW12 wasn't that powerful or economical in it's first release, Which is why the X-Type got the Ford diesels. but it's second incarnation (Found in the XF, Newer Mondeo's, and the current Defender) it's a sorted lump giving astonishing power outputs an economy! The same goes for the TDV6, the 3ltr is much better than the 2.7.

VW TDI's are good, but a little more noisy and they all seem to smoke when they get old, it's rare to see a Citroen/Peugeot chucking out black smoke.

Actually, are you going about this the right way. I mean could you fit a winch and battery on the boat? Laughing

Same engine family (Duratorq Lion), developed and built (V6 in Dagenham, V8 now in Mexico) by Ford.

Agreed they're the same family, though as PSA were intending to use the V6 in their own products, it's reasonable to assume they had a little more say in how it would turn out, than the V8 which was only really intended for LR and some international Ford models. As it was all PSA technology i still think PSA would have taken the lead on that one. PSA/Ford engines are a joint venture, PSA will have people at Dagenham, just like Ford will have people at where ever PSA's engine development centre is in France. You can't really say "that one was ford and that one was PSA", because from about 2000 onwards they're all jointly developed, but there will always be a dominant party and for the V6 i think that would have been PSA. The last 'Ford' diesel i can think of is the ZSD Puma engine, used in the Transit, X-type, TX-2 and Ducato/Relay/Boxer.

Where they're built and who by doesn't really matter in relation to where they're developed, Dagenham build engines for Ford as well as PSA (who used to supply them to BMW for the mini at Oxford as well as JLR). You can buy Citroens with Dagenham built engines and Fords with French (Metz i think) built engines, they use the capacity where ever it's available on the 4 pot DW engines.

(i didn't even have to wikipedia any of that....)

Ford are the dominant party as PSA don't exactly use massive numbers of the engines like jlr and ford do.

The psa version of the engine was slightly different as well as it only ever came with the twin turbo setup as well as being mounted transversely so needing that tweaking to work. FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
