So from 197 BHP to 280 BHP = 83 BHP gain just by re mapping. Defo faster than stock 330D.

I believe 330D can be mapped to 300BHP from 245BHP = 55BHP gain by re mapping. Brakes are defo better on 330D cars.


Was your remapping conservative? I believe 325D can be mapped to 285-300BHP.

[Jonnybgood]

Lci are 204 standard mate.Yes there was a few company's that offered 300 but thought id play it safe. Previous car was a focus st running 320 bhp and 380ftlb and tbh I don't think there is much in it now it's mapped. Very happy with it

Yes my 320d is 163bhp pre lci
My bro's pre lci 325d is 197bhp iirc


I guess a standard lci 320d with 184bhp would be close to a pre lci 325d with the 197bhp

But the tuning potential from the 325d is pretty amazing. Your talking an 80-100bhp increase with a remap which is pretty stonking

If its the same turbo and injectors....then yes it can be mapped to same level as 330d (LCI cars only).

If they are same, LCI 325d cars are real bargains!

Early LCI 320d was 177bhp... 184bhp was on later 2010 cars.

Confusion is on the Turbos.

If you search it with LCI 325 turbo specs, then it is common b.w 325 and 330D
http://www.realoem.com/bmw/showparts...11&fg=50&hl=32
http://www.realoem.com/bmw/partxref.do?part=11657796312

However if you search it with LCI 330D specs, then it shows a different turbo
http://www.realoem.com/bmw/showparts...=11&fg=50&hl=4
http://www.realoem.com/bmw/partxref....%0911657799759
Which is common b.w 325DN and 330DN. What the heck is N?

I can confirm that injectors, Turbos and Automatic transmission is different on 325d to 330d.

Here is 325D AT
http://www.realoem.com/bmw/showparts...24&hg=24&fg=05

And 330D AT
http://www.realoem.com/bmw/showparts...17&hg=24&fg=05


Considering all this, BHP gains on 325d are insane!

Thanks Scott.
I have taken the last 7 digits of VIN off 10/09 325D and compared it to same age 10/09 330D. Part number for the injector and turbos are different.


Here is what you get by entering last 7 digits of 325D VIN

I bet you are happy. I sat in 2010 E92 325D which was mapped to 290BHP. Acceleration was immense.

So why should you go for 330d....

And then ukbeemerboy posted the response

Yeah I said the same, but obviously after further looking, there is more differences than I first thought !

Still wouldn't say no to a 325d

[FRG]

Taking the part numbers from an '09 325d will show different to a 330d as the N57 wasn't put into the 325d until about '11 I think. My old one was the M57 engine.

I've read previously on several forums, including this one that the N57 25d unit and N57 30d units are identical apart from the map. I would have had a 525d no worries but this 530d came up at the right price so I took it.

Alex
agreed with you. Its a no go at the moment. I guess I will be keeping my car for another year to have a decent LCI 330d. Exception is if I have to do mega mileages and then 320d would be the way to go.

Funny I spotted it for sale 2 days ago but never realized that it comes from a fellow forum member. Excellent car mate, but I'm after E91 this time.

I do not think this car will stay long for sale.

Fair enough mate, E91 would have been my choice had I stayed with a 3er. Don't rule out an N57 (204) 25d though, they are the same as the N57 30d and a trip to DMS would have it flying

I get confused by this ... DMS remapped my 330d LCI to 305bhp a couple of weeks after remapping a 325d LCI to 285bhp.

They said there were subtle differences - but I have seen another rolling road graph from DMS posted on here that showed 300bhp from a 325d LCI !

Maybe there are differences depending on ECU or other bits on the 325d so they remap very high but only some quite as high as a 330d LCI - if that makes sense !

The DMS remap is stunning - so smooth and though it doesn't feel outrageous compared to the std 330d LCI it is in reality - you only need to watch the speedo !!

The LCI 330d feels quite a bit more punchy that a non LCI so the difference when mapped is not as great. Coming from a 204bhp 325d LCI the difference must be incredible !

Thanks mate. Real OEM shows different part numbers whereas people say that they are same.

But maybe that is why DMS say they are different and the 2 cars mapped by them produced different figures - 285bhp to 300bhp between 2 cars is quite possible though.

He was very definite to me - almost the same but not quite ... in small ways - thus the 330d will always produce more.

Ok guys. Cracked it after spending 15-20 minutes.

Pre 03/2010 part numbers for injector, turbos and transmission on 325 are different to 330d.

However from 03/2010 all the part numbers are identical.

Hence DMS has two different results.

Good news for me

325D is a bargain if you can find the right one. Remapped gains are nearly equal to 330D.

[Jase 320d]

Even the older 325d is still a decent buy

A few k cheaper than a 330d and if all you want is 270-280bhp which imo is fairly ample you can't go wrong imo

As I thought. The introduction of the N57 in 25d guise

Actually they launched N57 in 09/09. So some 325d from that production date may have N57.

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

yes, Jase. But if you can get the right engine to tune and get the power equal to 330d, then why not?
