F30 335D Remap...
Discussion
I dont understand your argument at all ,you can only have a 335d in Xdrive so that has to be apples with apples theres no oranges....anyway this is intersting,

Your post earlier today suggested there was a significant mpg difference between a 330d and a 335d and that that was purely a consequence of the engines; however, that's only valid if you're comparing like for like models (so F30 330d X-Drive v F30 335d, F31 330d X-drive v F31 335d, etc). The reality, however, is that there isn't a significant difference in mpg due to the engines so perhaps a more reasonable comment would have been I don't think the downsides of an X-Drive are worth it and therefore I wouldn't buy a 335d?

The OP asked about remaps.
It seems a pity this thread has been hijacked by the - my car does a million miles on a gallon brigade.
It was answered - as all F30 335d's are stil in OEM warranty you'd be pretty silly to consider it unless you go for Hartage or Burds but that's £2-3k I d guess from the original post he isn't interested in such a spentmc so it's all a moot point.

oP if your happy with spending up to £3k on a remap and invalidate warranty please post up.

Also add in that my 640d is chipped and has been since 500 miles
Boyblue makes a fair point when he says this thread has moved a bit off topic! However, the engine in your 640d is the same as the one in the 335d so can I ask who did your remap, what were the gains in bhp and torque and what was the approximate cost? Also, did the remap invalidate the warranty?JNW1 said:

I'm sure he will answer himself but another 640d owner on a different thread had his mapped I think it meant 360/380bhp it was a Hartage offering and about £2k for the upgrade/remap. Monty Python said:

Thanks for all the input guys. Looks like the DMS option looks good at around £1k and they say 395bhp and 560nm...
If I was spending £2-3k for it - I'd get the ACS one thats ok under warranty but seems steep...
Might be best to wait 3 years and get it done out of warranty.
Do you have a link for the DMS?If I was spending £2-3k for it - I'd get the ACS one thats ok under warranty but seems steep...

The Celtic tuning one is under half the price of the DMS as I understand

Kind of expensive - £600 for an extra 20bhp compared to Superchips/E-maps.If I was spending £2-3k for it - I'd get the ACS one thats ok under warranty but seems steep...

All chips invalidate parts of warranty i.e. the bits that could theoretically be shagged by the chip. The main exception is the ACS which is massively over priced in my opinion.I used a German company called RaceChip and bought the Ultimate version and although it is adjustable I've left it on their out of the box settings. I've been very happy with it and not had any engine warning lights etc. They claim 370bhp and 730nm of torque and that seems pretty accurate from the US boards where I've seen the gains on US 35d engines.
I would be very wary of remaps as you cannot remap the ECU without removing the ECU from the car and breaking it apart - theres not OBD option.
If available I would have bought the Superchips Ultimate, but even their version of the chip is rebadged box from a 3rd party.
I did a stack of research on the US websites (mainly Bimmerpost) from X5 forums and also some UK sites.

OBD from yesterdays drive from Maidenhead to Nottingham. It is helped by the long 50mph SPECS zone on the M1, but I did do 75-85mph at times.
Not sure how accurate your on-board computer is (mine's about 5% optimistic on mpg) but an impressive result nevertheless; never bothered re-setting the trip for an individual journey but seriously doubt whether my F31 would match those figures! Suppose that's a combination of the effect of the X-Drive plus (I suspect) the 3-Series Touring is probably less aerodynamic than a 6-Series coupe and that no doubt has an effect when you're cruising at motorway speeds. Just returning to the subject of the remap, did you find that that had an adverse affect on mpg? Clearly it will if you're using the extra performance on a regular basis but a lot of tuners claim that in normal use mpg actually improves following a remap (or at worst there's no deterioration in that respect).JNW1 said:

I'd say mine is probably a little optimistic, never really done the actual mpg just use the OBC. But you are right, X-Drive does rob you of mpg, not sure what the difference is but I think you would lose 15% over a RWD car.Not sure if the chip has had an impact on the mpg either positively or negatively as I did it so early on (900 miles or so).
Overall I can't complain as for the age of the engine, notwithstanding the revisions over the years it gets great results with great power. Not sure how the 313hp Audi engine compares.

At heart I'll always be a petrolhead but as oil burners go I think the BMW 35d engine takes a lot of beating. I think your numbers tend to confirm that any inherent lack of efficiency compared to the 30d is just a myth and having driven both there's no doubt in my mind that the 35d is the sweeter engine to sit behind; if I was choosing an F31 again now I think I'd go for the new 340i but if I was forced to go diesel it would still be the 335d!

Provided you like AWD and non Msport suspension? Otherwise you go RWD F30/31 330d with PPK which is cheaper than the x35d to boot & currently BMW do not make a PPK for the x35d ---- I wonder why that is while every other model has it, is it due to the fact it will can abalone sales from the high end petrol/to some buyers make the gap to the M3 on paper seem small/aware on PH we all know it's much more than that but it might be the logic.
