I'm going to get my 325d remapped. It's an lci which I believe is exactly same as 330d?
So can I expect same remapped performance as 330d?
Can't see why not but someone might be able to tell me different.
Standard bhp is 204, can I assume I can get into 270's?

[makkan00]

03/10 onward 325d has similar engine to 330d and can be tuned equivalent to 330d.
However the brake setup is different on both cars and 325d lacks jet washers for the headlights.

[mikeouk]

Mine has jet washers, it's an e92 though, thought they were standard?

[Reece]

Just had a quick scan on a few companies, seems ul make about 270bhp and 565nm torque as were the 330d will make 300+bhp and 620+nm torque.
So you will make good gains but on paper wont be as quick as the 330d

I've referred to e90/91 differences.
E92/93 have jet washers as standard as they all come with xenon.
If you search 'why not lci 325d?' on this forum then you will find detailed comparison of 325/330d lci cars.

Still a bit confused tbh even after reading that thread.
My understanding is lci model 325d and 330d are identical with all parts. So how come they can't both be mapped to same power/torque?
If I can get 270 I'd be more than happy with that anyway, just wondering why the differance?

[SO8]

DMS remapped a 325d LCI auto to 270 bhp .... but remapped my 330d LCI auto to 305 bhp.

They said the cars are not 100% identical but almost - give them a ring. It may be the 325d was not as 'loose' as my 330d thus the 35bhp power difference ... though that is quite a bit ! They def said there were differences - but I don't know what as people said they are the same.

[M4rius]

325d has different injectors and map , in theory bigger injectors and proper map(not generic of the shelf crap) should up the power to ~300bhp

There you go....

N57 is the key for the tuning equal to 330d.

So if you have N57, then it should be remapped equivalent to 330d.

So good luck!

I'm thinking of getting my pre lci 330d remapped, can you recommend anyone in midlands area?

[Ajs_435d]

That's rubbish a 325d cannot be remapped to 330bhp in stock format, firstly the injectors and turbo do not support those levels and bmw might as well have done away with the 330d. There are small differences between the 325d and 330d but they map to near enough the same level.

I extensively looked into this and seen dyno graphs at ecotune as do their own maps.

Unfortunately, I will have to say that you haven't studied it 'enough'.
I have gathered all the evidence on the thread which I linked in my last post.
Even gearbox is similar.
Difference is brakes.

Now if a tuner cannot tune it or the dme has different chips, I cannot comment on it. Rest, injectors, engine, turbos and gearbox (all parts) have similar part numbers.

And I have clearly mentioned the engine code.

[SO8]

As I said earlier DMS state they are 'almost' the same ... but that - with them - meant 270bhp on a 325d LCI and 305bhp on a 330d LCI.

If the OP rings DMS I am sure they will explain.

We can ask ecotune (who primarily tune bmws) and they'd put it to bed, it will not make 330bhp. I can't be bothered arguing so your right a+.

I just don't want the op to think he/she will get this power.

[ELD70]

Does the 325d LCI have a different brake set up from the 330dLCI?

[SO8]

I think 270bhp in a 325d will feel great. 305bhp in my 330d was difficult to put down to the tarmac. I have been used to more powerful cars which have been awkward to deploy power but the map on the 330d whilst being brilliant was more than I needed.

My 330d LCI has gone but when DMS took the map off I did say to them that a map between 245bhp std and 305bhp would be more useable. They said they could easily do one but most people just want the 'most'. They still stick with it being driveable though which is why I would thoroughly recommend them. I will no doubt go back to them in years to come but may bear in mind their comments that they can 'adjust' the power output as I, for one, seem to like a bit more without going mad

Are the part numbers the same or similar? The parts cannot be the same if the part numbers are different by 1 number.

Read the thread.
They are same.

[Digitalize]

The statement that the parts can't be the same if the part numbers aren't the same is incorrect. They can do whatever they want. The parts may be identical, but differ by one digit to differentiate on which part goes on a 325D and on a 330D, the number doesn't suddenly make the part different.

If the numbers are the same, you'd hope they couldn't be different though, otherwise the system is broken.

Really? I was referring to your earlier message where you said they were similar.

My comment was based on my experience working at several UK OEM's. I have yet to come across where the same part having different part numbers. For example, at JLR many parts were shared with Ford cars yet the part number remained the same. This was the same at Aston and also at Nissan who use Renault parts.

Also saying that, I cant see your theory being correct regarding BMW. There are countless common parts between 325d and 330d, E90's and other BMW's yet they have the same part number.

Happy to be proved wrong though.

[mikeouk]

I know when I had my 313 alloys replaced under warranty the dealer told me the newer wheels had a different part number to the ones on my car, presumably due to there being corrosion issues on originals and being able to differentiate .
Nothing to do with the 325d/330d debate I know, but an example of a part that looks the same having a different part number.

Some guys have attitude for no reason!
You can comment on same or similar but not bother to click the link (to oem website) and compare yourself!
