Remap 3.0d sport X5 ECU for more power??
 

Has anyone any experience with having the X5 remapped or chipped to achieve more power and torque.

I have a 2001 3.0d sport in the UK the power is retarded to 184bhp with 410Nm of torque.

The standard ECU can be re-mapped to achieve the power which the X5 was originally meant to have when designed in Germany. This will take the power to 217bhp with 500Nm of torque.

Has anyone had this done and does it improve the fuel consumption.

I cant decide whether to do it or not.

Thoughts anyone? :thumbup:

I have a 2003 3.0d with a STEINBAUER P-Box it improves the power up to 212bhp and 468Nm of torque. I haven’t done the remapping for several reasons:

- The gearbox cant take more than 500Nm of torque.

- Each time you go to the dealer, BMW will reset the ECU.

- Lost of the manufacturer guarantee. BMW can see if there was a modification in the software.

As for the fuel consumption, you have to consider an increase of fuel consumption in case of a pretty fast driving.
If you maintain your manner of driving you can expect the same or in some cases even lower fuel consumption.

Cheers

Tunit Box or the like would do the trick for you in the UK. Simple and easy to fit and remove, located down stream from ecu, adjustable, up to 30% power boost, do a search on "diesel power" on this forum for lots more info.

:iagree: Go for the tunit box. I fitted one after 5000 miles and have had it in the car for the last 10000 miles - fantastic! Loads more power and smoother delivery + a couple of mpg more. My local BMW dealer just turn a blind eye to it - the car is just over a year old now - it's the best £500 I've ever spent. There are 9 settings - mines on 7. Giving me an extra 30Bhp or so (from 218, now to almost 250Bhp).

The tuning companies are half right!
Bmw dealer will not go looking to see if car has been mapped!But if its a warranty issue ,they will look for anything that may affect it!They will simply need to log live data of a mapped car and compare it to a standard car...
They cant see if car is mapped just by simply connecting to a Diag...!

powers1 thanks but log life data?is that log love data you mean?whilst the car is running I guess?

Yes.Live data is obviously logged with car running.
At the dealers they "Diag" the car at idle and occasionally rev it (depending on what they are testing) but because the car is not under load,a remapped car will not register parameter values much different from a standard car!
This is why "tuners" say it wont be noticeable,if your car is mapped!
Its a bit of a joke ,one comment you quoted a tuner saying that the dealer doesnt have sophisticated equipment to be able to check if your car is mapped!You can get a £30.00 tool from Ebay that will read/write your Ecu:rofl:


Omodos,what model and year car do have?

I see your point about ebay 'toys' being able to read/write ecu hehehehe ok 2004 x5 3.0d is what I have, however as you say the ecu can be read with an ebay gizmo? but changes to ecu parameters can only be seen if the car is under load conditions?not just by the odd revving in park mode?

Since I posted this thread I purchased the tools so I could remap the ecu myself. The new map files are pre-tuned by a tuning house in Germany. The difference is makes to the car is brilliant and BMW have never noticed any changes when it's been in for servicing. Obviously I cannot be sure exactly what power increase I have gained without putting it on a rolling road/dyno but hey, it's well worth it!
