BMW 330D M Sport

[eastender]

Hi everyone. I am after some advice on the car i have just bought, 330D M Sport Automatic, i have been told that this car car be slightly tuned and get better fuel efficiency at the same time.
Owners ,what do you think of this ? is it worth doing and any things to look for

[mrmr96]

- remove swirl flaps (to prevent them failing and getting sucked into engine)
- replace crank case breather with vortex type (to prevent blockage, crank case pressurising oil and busting oil seals in turbo, killing it)
- decat and remap will improve performance and economy

Remap will boost that up nicely to nearly 290bhp and enough torque to pull up trees.

I've mapped 3 BMW's now and each time mpg average has risen by about 4mpg over a long commute.

Dms or autologic are both effective.

guys thanks for replies, i live in the Essex area can you recommend anyone to do these upgrades.
Thanks again
Gary

Have done both a 330d and 530d at AMD at Lakeside. They seem a bit pricey compared with some of the prices people quote on PH but are cheaper than DMS. They have a rolling road to give you before and after figures. Out of interest I got the following:

330d
- before 245bhp / 396lb/ft (rolling road figures & higher than quoted spec)
- after 301bhp / 485lb/ft

530d (same engine as 330d, both 2006 cars)
- before 227bhp / 365lb/ft
- after 278bhp / 405lb/ft

Not entirely sure why the difference. AMD guys weren't surprised though and said it was quite common to get such variations.

The only issue i have with not mapping my 320d sport is that churchill insurance will not cover remaps.

What did you guys do with regards to the insurance aspect of remapping?

[pointedstarman]

I was told by someone in the know that there is little or no chance of someone finding out if a car is remapped so I acted accordingly....;)

Don't have a remapped car now and, tbh, probably wouldn't bother in the future. The 330d I had was ludicrous but the 530d didn't fell that different.

Have 18 month old twins now so don't flex the right foot that much anymore and anyone remapping to improve fuel economy needs to check the maths because it's unlikely you'll ever recoup the cost of the remap in improved mpg.

interesting thread. I have the same engine, beit a manual and have been thinking about a remap. Am I right in thinking that its best to steer away from this for a manual as it can eat the manual box, but in this instance the auto is a lot better at handling the extra power?

[pointedstarman]

As I understand it, though I'm not an expert, the 335d is auto only because the power & torque figures were in excess of the rating of the manual box. Remapping a 330d will give similar or even more power and torque than a standard 335d. I believe BMW have fairly generous design tolerances so a remapped 330d manual may well be ok but you are taking a risk. I suspect if you end up with power and particularly torque figures in line with what I got after a remap a manual box would struggle.

Unless you've had a new clutch and flywheel recently, a remap on a manual 330d will have them gone in no time, and I'm posting this from experience not what I've read on the Internet. It's not the gearbox that can't cope it the bits 287 865 063between the engine and gearbox. An uprated clutch might help but you still have the issue of the dual mass flywheel. When I checked when replacing mine there was no solid flywheel in production so there was no way of uprating it.

^^^^^

OP won't be having any clutch issues from a remap as his car is an auto.

PWM ltd, are in Essex and well versed in swirl flap removal and all things diesel BMW.

Edit'd to correct link.

Answering a question re manual boxes from later in the thread

I had a conversation with AMD Tuning yesterday and they have just done a 330D, after a remap it was pushing a extra 60bhp and the torque went up to around 450, with new pipercross filter and remap and rolling road tuned, comes out at around £400 plus dreaded vat. That is a lot of difference for a diesel.
It will be pushing more power that my other toy my TVR shocking.

Speak to Simon at Emaps, he's really highly regarded on the BMW scene and he did my 330d a few years ago, top guy, quality job and will come to you as he's mobile.

[Billyray911]

Another vote for Emaps...
Have you decided whether you want a remap or a tuning box.
Have a look at companies such as Evolve and DTuk amongs others.
I would say do a little but more research on what products are out there.
I don't know what year your car is(sorry if I've missed it) but if it's relevant,get onto E90 post or BMWland as there is a wealth of info.

So you were driving uninsured since you didn't declare the modification. Should you have caused a fatality in the event of an accident (for example killed someone else's child) , the insurance company would look for any modification to the car that wasn't decalred on the policy. This includes remaps, particularly on turbo powered cars and of course hence particularly diesels.

You say you have 18 months old twins now, that's very nice but other people's 18 month old children are just as nice. I'm sure you wouldn't like to have an unisnusred driver (due to undeclared mods) drive into your car whilst your children are on board.

The above sentence is the bottom line. I have read on other BMW forums and the general consensus is that the insurer WILL look to see if you have a remap in the event of an accident. It is not too difficult to find out whether a car has a remap or not either.

Definately not worth risking, because as Silver993tt states, you are driving uninsured.

What kind of question is that?

I am not talking about whether it stops someone, but its wrong in the eyes of the insurance company FULL STOP.

[a4cabrio]

What happens if you buy a car that's been remapped but the previous owner fails to inform you of the remap and you have an accident and your insurance finds the car has been mapped????

[Zachlain]

My understanding is that you are still responsible.
The way the insurance company looks at it is that you have to find out if a car has modifications or not. Not knowing is not an excuse.
