530xd 8BC_POWER_REDUCTION_II

Hi all,

i have a question. In Italy there is a tax for car that have more than 185Kw.
Bmw have a good idea and in the Italy store you can buy g30 limited to 183Kw (without additional tax).

I hope that i can explain correctly.

The 2 version (183Kw and 195kw) have the same engine. Only limited in ecu.

My g30 is 183Kw and in FA have a code option 8BC_POWER_REDUCTION_II.
I read that in some ways is possible to remove it... can every one help me please?

There is someone that can help me to restore original power?

Thanks

The ECU for the G series cars hasnt been cracked the only option is to get a piggy back tuning box.

Alternatively wait until the 530d mppk is (eventually) released - that will most likely come with a new ECU

It is impossible to code 183Kw to 195Kw. There is a reason why you have bought 183Kw: less taxes, because of less CO2 emissions . If you are to increase the power, the emssions can increase as well. Meaning you will have to pay more taxes. Another thing is the case of warranty from BMW. You might lose warranty.

To code other things like windows, seat belts etc. is one thing, but to change engine ECU, mapping etc. requires a professional.

In Italy the motor 183 Kw is only for tax...not for emissions.
I'm a tuner and i have the DimSport Professional kit but the new Bosch cannot remapped for now.
I have a RapidTDM module by Dimsport but if i can have 15cv more by the original ecu is better.

I have read in some post that this mod is possible (the same power reduction was present in some other bmw model) but i don't know the right step.

I suspect that BMW has done something similar with the 530e to meet emission goals. There is 25 HP more in the engine in the 530e than in the 330e but it posts the same combined HP. My guess is that there is something magical in at least one jurisdiction that caused BMW to limit the HP of the 530e in the ECU.
