Ok I know its too soon my zds only done 260 miles but whats the status of remapping the turbos.

I did it on my TT many years ago was 225 got it up to 260. 2 years later they released a 250 based on remapped 225.

yes it may void wrty and need uprated breaks and clutch but whats going on.
 
I remapped mine when I hit 1200 miles (running in period). It only effects the warranty if BMW prove the remap caused the problem.
 
None of the big names seem to offer anything yet in terms of remapping for the 20i and 28i. Last time I looked DMS, Superchips, Revo still had nothing listed.

I guess the fact that the engine has only been available for a relatively short time means they are all still within the warranty period and so presumably there isnt a big enough market yet as many will be concerned about warranty issues?
 
seems a bit of a no brainer to me, why buy a new car with an engine that you are not happy with ? that is also going to drop money like a stone, if you went for that size engine on reasons of economy then what you will lose on depreceation will outweigh many times over the running costs of a decent engine. abetter buy surely would have been a 2 year old low miles garage queen 35i, mor fun more desirable and more easy to sell later , plus no money to waste on over exagerated chips. simples !!! :poke: :thumbsup:
 
I would agree just go for the larger engine over a remap any day. If your engine goes pop BMW will know what's caused it, they're not daft. If you must go for a remap make sure it's warranted so it doesn't end in tears.

I would have gone for the bigger engine but the V8 version of the Z4 is £350k and isn't road legal :)

Manhart Racing will put a v8 or v10 in your e89 for you, but only one problem with that, the cost.........80k euros. :lol:

Are you referring to the Quattro Sport 240?

Tempting :)

Wake up! Wake up!

Daydreaming again :oops:
 
lol.

Ok ok ok. I would love a 3.0 twin turbo but hay Im cheap. so I have opted for 2.8.

I Just cant justify the many many thousands.
ie £45K + extras V £37K (but we are getting free M sport so its £35K)

Then the cost in feeding the plant, insurance, tax and then the loss when I px. the 3.5 BMW is suggesting £15K for the 3.5S v £13.8K for 2.8 M sport. I got more then 13K after 3 years 2 month for my 3.0 auto S drive so its relative difference!!! but in 3 years the new z4 will be out so we will loose lots of cash then.

Hay even if I had the 3.5 I would be asking the same question.



Now my dad has a balingo and even he has it rempped and gets his extra 24bhp better economy and he like me did not want to get the larger engine.

My Audi TT 225 had a standard remap to 260 and even audi in the end put a remap 225 on the market the 250 ripping the rear seats out and throwing in a cargo net lol.

I would look to push it a few bhp after its run in not thinking of going to over 300

whats interesting is the 2.8 is well nibbling at the 3.5 is 0.5 seconds worth the extra and loss in mpg i.e 41 down to 30, hay a few bhp remap will make this sooo near to it.

Whats the difference between the 3.5 and 3.5s? remap and it looks like its better mpg to boot.

Not bad for £400 are you going for it ?

I wonder if the low down power would be affected ?
 
Would like to see the curves but it shows that several / 8 are uploaded. Im just running mine in now so will wait a bit lol
 
I refer to unrelated cars but I have some experience with remapping - my previous Focus ST was remapped by Dreamscience handheld tuner via the OBD port - you could choose from 4 states of tune ranging from 240 bhp to 270 bhp - the latter also increased torque to 330lb ft which as you can imagine ate front tyres. Aside from the tyres the car performed without fault - it was fully serviced at Ford (i just returned the car to standard for service time)

My current car has a superchips bluefin handheld tuner - takes power from 200 to 250 ish, it has been on the car from 8k and it is now on 34k - never missed a beat and the DSG gearbox copes well with the extra shove. Full VW service history and it had a coil pack replaced whilst it was tuned under warranty with no issues. (the coil pack failed due to poor manufacture it was nothing to do with the tuning) I have seen increases in mpg too because the dsg learns the power of the engine and doesn't down change as frequently, instead using the higher torque available.

If I end up with a 20i Z4 then I will surely be trying a remap - the technology available these days is very advanced and they tailor it very well for the specific model.

QS is 240bhp, it's the V6 that is 250.
 
Lol 10 horses off, It was 8 years ago, but your right the 3.2 V6 was 250, but pumping a few more bhp from the 225.

Lots of reasons...optimised for lower grade fuel, not all markets/buyers will put the best available in the tank. Model differentiation 18/20/28 mostly stifled versions of the same car...injectors and tune are the only changes. Who would buy the heavier/thirstier/more expensive 30/35 models if the 28 could be persuaded to pump out 300+bhp?

TBH I cant see why it wouldn't/couldn't, Mitsubishi get 400+ from a 2l turbo unit and my 20 feels really under stressed as standard...I would love to give BMW a couple of more thousand next time and drive away with a howling, turbo screaming 340bhp version!

I may be odd, perhaps its the years of biking, but I like the feeling of working a smaller engine to get the best from it!

There are slight tolerances within engine castings, exhaust systems.
This is one of the reasons a remap on a rolling road showing any peaks or troughs is dealt with. You won't get this with a generic plug in box which i doubt was made in the UK for our climate.
The Zed is also sold all over the world and used in counties with high altitude, hotter climates and different humidities. BMW need to set the ECU so that the engine is safe in all these different countries.
