Hi

I want to upgrade my old alternator Denso 170 A for 210 A

Service bmw said they need to program all car and also program in ecu

Could you tell me they are right?

With foxconn i can do this on my own?

I am not sure what they mean by program all the car. Just the dme module. What did you Foxconn? Never heard of it.

Either way your car will run fine with the 210a alternator though. The main reason why you need to program the dme is so that the battery is charged properly. The downside if you don't program the dme is that the battery may last 4 years instead of 6 or 7.

I have used that scanner. Don't rember any options for changing the alternator capacity.

ok thanks for info i got this reprograming all car info from special BMW service so...

anyway there is option with foxwell 510 setup that dme 

and change charging not to 80 procent like they said is proeco for 100 procent?

 

Thank you MB

No because you are upgrading the current output not downgrading it. If you went the other way I would be more worried.

You should be able to with inpa. Look under the DME module. It's been a while that I used inpa so I don't rember the exact steps.
