BMW E90 320d remap

[Twinz]

@Kaaba...you the man...i am in full agreement:thumbsup::thumbsup:

 

[Mr Nitelife]

Hi Guys,

Just a few questions, firstly does anyone know of a BMW club in Durban?

Secondly, which option is better when it comes to modifying the ecu of a 2010, 320D Motorsport. Piggyback or Software?
Thirdly, can anyone recommend any places or brands in the Durban area?

Thanks

My 2010 320d stock vs Xcede remap
156BHP ATW and 326 NM Stock
196BHP ATW and 402 NM Xcede Remapped

'About' 170kw and 460nm ATF

[Mr Nitelife]

Thanks, Z3mCoupe the figures are impressive

Would you recommend Xcede?

With the Xcede remapping of the ECU, can it be picked up by manufacturer when it goes in for services?

 

[Z3mCoupe]

I would definately recommend them! Did my mcoupe! Currently fastest Z3 aspirated in the country. 30,000kms no problems
Had the remap on my 320d now for 30,000kms, everyday map. Fuel consumption is down by about 0.5l/100kms

Remap cannot be picked up by dealer. Went in for 2 services already with the remap on.

 

[Obviously]

I thought the less powerful 320d (2005-2007) had 120 kw, stock. The 2008 and up have 130kw stock. Correct me if I'm wrong. What kind of torque are you getting when remapped ? The biggest jump I've seen is to 450 nm of torque.

...The thing is, I've heard from people about the high maintenence costs on diesels vs petrol but I haven't heard too many stories of tune ups ruining engines or reducing the life of the drivetrain or anything.

2005-2007 = 115kW/330Nm. 2007-2008 = 125kW/340Nm. 2008-2010 = 135kW/350Nm. 2010> = 135kW/380Nm. I got 459Nm ATW, with an earlier dev file and bear in mind that this is at the powersapping Reef. This would equate to well over 500Nm at the flywheel. With the current file that the car has on the moment, it should be stronger still. I know someone who had his 120d remapped not long after he bought it. He used that car for about 6 years and rocked up 150-200k that included regular serious trackday driving on his part and from what I hear, it suffered no major issues/turbo failures etc. before he sold it.:shocked:

Only thing i'm concerned with is the extra stress on the turbos and everything else. Would it not be a wise move to perhaps detune the turbo and have a wider torque curve ? Can that even be done ? To smoothen the torque curve from low to high without boosting but rather modifying the torque curve which may result in less torque down low. The way I'm thinking is that by detuning the turbo there will be less stress so a longer life plus torque would be more consistent at the upper end.

I know many people have a remap and gain between 50-80 nm of torque but the more I think about it, the more concerned I am about it. I'm someone who doesn't earn a lot of cash to spend on things going wrong. If I have a remap I think the chances are that MORE things will go wrong and the added stresses on the engine will reduce the life quite a bit.

Please guys, correct me if I'm wrong on this. I'm just extra cautious these days. As you guys know, I've got a 320i. It's kak slow. The only time it's not kak slow is when I turn my AC off. But AC on, it's a dog. I struggle to do any overtaking. Can't believe that AC could use up so much power. Maybe it's a BMW thing.

 

[P1000]

I do not notice my AC on my 530d at all. But then, its got a variable compression ratio which basically means that it is almost switched off when you press the loud pedal. Maybe your problem is that you bought the bottom of the range car, and expect it to have similar features to a much more expensive car?

 

[Olorin]

No, I didn't notice the AC on my Corolla 140i )), but on the 320i, it makes a BIG difference. I can't drive quickly with the AC on, it's just a chore. Without it I can overtake nicely and everything is just quicker....

 

[P1000]

I believe the aircon on the corolla was probably much lower power unit, whereas the one on your 320 is probably the same as the one in a 330, and it does not have the variable compression feature. But, I feel your pain. There are two solutions to your problem: get a 330, or switch off the AC when you want to overtake

 

[Olorin]

Yes, I have many options at my disposal. I'm busy pulling my hair out whether I should save up and get a 325i or a 320d. Of course, it would be second hand. No way can I afford R400k+ for a 325i-330i. I can afford R165-180000, but that's kind of my limit.

The thing is, I've been told that diesels don't hold their value very well vs petrol engines. Is that true ?

 

[P1000]

Only once they get past 7 yrs

See my last post above. If I got/get even 150 000km without opening the engine/overhauling the turbo etc. on the "d", I would be very happy. I'm no tuner but the only way I believe you're going "detune" a diesel's turbo and alter its torque curve without adding boost, is by getting someone to remap the car for you, reducing boost to blow stock levels and overfueling the car and possibly advancing injection timing too. I wouldn't even think of doing something like that, I'd rather just fit an intake kit for better sound/high RPM performance, or just leave the car std. if I were you. High EGT's are a major problem with overfueled diesel cars even though this is an easy way of making "smoky" power, without big boost. Prior to the increase in the availability of 50PPM diesel, all diesel BMW's sold in S.A. were "factory detuned". In the 320d that would be the 115kW as well as the 125kW models. Perhaps you should consider one of these, if you are looking for a "detuned" car, eg. if obtaining 50PPM diesel is a problem for you. With regards to software, a tuner such as Xcede can phase in boost progressively, so that that will be less wheelspin and/or stress on drivetrain components and as a result, your torque peak will theoretically be higher. No need to worry about torque dropping off more than stock at the upper end on a remapped car. My car holds power/torque better at the higher rpms than stock, altthough this may also have something to do with the intake kit that I fitted. In general the power/torque curves of a remapped diesel mirror those of the std. car's although with much, much higher figures. I reckon get the 320d first before thinking of any mods. I'm willing to bet that you will enjoy it much more than your 320i, perhaps so much so that you wouldn't even want to modify it.

 

[Olorin]

This is my major obstacle. Give my budget, I can only afford a car that is around 4-5 years old. If I get a 320d that is a 2006 model, you guys are basically telling me that I'm good for another 3 years and then I can expect problems (ie 7 years). Is that really what one can expect from a diesel ? Turbo's and other nasty things rearing their ugly head after 6-7 years ?

Because of my budget, I can't really afford a 2007-2008 model. However I can afford a 2005 petrol 325i which is a big upgrade over a 320i. If I save up a little more I might even be able to get a 330i, again 2005 model. And these cars will last, I take it, a lot longer than a 2005-2007 diesel, especially if I decide to keep it for the next 5-10 years ? Then again, because of this economy, I might find myself in a situation where I can't upgrade...again. So..difficult one.

 

[Ziyaad]

My mom has a 2010 320i Streptronic..i can't even feel the difference between the AC on & off! She had a 2008 320d before trading in..she says the 320i is slow & heavy on petrol! 320d FTW! :thumbsup:

 

[Olorin]

Yeah, but who knows what advances were made from 2005 to 2010 in air con technology. Perhaps more efficient air con perhaps ? I don't understand how anyone could buy a 320i new. I just don't. Granted, the 2010 model is more powerful than mine, but it's not going to be a night/day difference and you are spending over R350k for a model with a couple of extras.

Everyone says diesel (on here) and everyone says ditch diesel (also on here and elsewhere) and stick with petrol. So it's obviously 50/50 at the moment. It's either long life and decent engine sounds with decent speed, or shorter life, less resale value, more issues and a truck like sound, but excellent fuel consumption, and excellent torque figures. Hmmm.....life is a bitch.

The truck like sound can be sorted out. My car doesn't sound, or even idle much like a diesel anymore. I have heard rumours of diesel's having poor resale values compared to the petrols in the past but just try and find a used 120d, or 320d, priced lower, or the same as a similarly specced/same year model 120i or 320i with similar mileage these days. They just don't seem to exist, or at least I haven't seen any because they just don't seem to sit in the showrooms long enough. The large new purchase price premium for a 120d/320d over a 120i/320i seems to have carried along to the used car showrooms from what I've seen as well. Check the M&M Digest prices to confirm. And as for decent speed, well that's spelt with a "d".

 

[Vishalan]

Hi guys,

I had my 320D E90 remapped and its now a seriuos beast - however in electronic dash w.r.to fuel mileage seems to fluctuate.
I drive normal not hard to try and manage this. Is this normal??

 

[K1300S]

I got a Quote from Xcede for my 2011 320D:

the cost is R 4 500 for repgramming of the ECU. Takes 1 hour. Will increase the power by 35kw and the torque by 100NM.

This sounds almost to good to be true....

Surely software only can't do this?
What does this do to my cars engine, gearbox, drivetrain etc...?

Where are the guys that have done this already?
