does anyone have experience with bmw serie1 163cv dpf?how much diesel can you? you give them?they say that it digests enough!
thanks

guido did not quite understand the question...but you intend to map the drive with the fap to her??
then, however, I believe that it is a question subjective..all? it seems obvious that a given engine to like ? its conformation can "digest" more or less fuel than another engine....the limit to the iq in my opinion ? given by the mechanical resistance of some organs in the first place of the clutch and the turbine, or then from the ****s fumosit? admitted in relation to the performance....
paradoxically,prendedo in exam 2 cars identical and mappadonle to the same manira you might have a difference of performance and fumosit? only by mounting on one of the 2 filter sports,converrai with me ? a application your that the time that is.....

charles I'm sorry, but a 7% diesel fuel more.... but how? press the rail,that does not mean you necessarily increase the press of 7%, or tinj, or "pedal" or lim torque??
the cio? it seems to me too general a statement....

perhaps referring to the tinj, if ? the reference IMHO you might as well give it a 6 or 7%, of course ? to see the rest. If you remove the DPF ? much better. Rightly every car has a history of s? and it would also assessed the general state of the fuel injection system

I sona got to 15% of tinj at 2000 rpm 100% load to climb to the increasing rpm,obviously adapting turbo.rail,advances,limiters,egr.....

not ? too the 15% with the DPF ? rarely arrive at 15% even without the filter

low rpm does not go beyond the 6-8%, and then slowly progressiavamente at high rpm you can get to 12-15%.

for me, making these speeches without seeing the map ? almost useless on a car like my 120d without fap if by 15% of the injection time and try to correct the diesel in the pi? only with the turbo pressure you have the car smokes like a chimney, not have smoke, you are obligated to tap the advances.

let's say that up to 9 or 10% YOU can't not have fumosit? raising the turbo about 180punti

guidotacco asked as max % to be able to give on a bmw with fap then the rest of the map, not the views of anyone and we do not know the other,with 15% of diesel fuel, the car does not smoke, of course I said at high rpm because if you would give this increase down the fap is intaserebbe quickly.

ori as diesel injects the car in question??

I bmw without fap arrival: 30% and over,of course, well given, and with other devices,and the smoke ? acceptable!

yes, but the eg if the car ori injects 60mm3 with the 30% diesel fuel more you 78mm3....that it's not too many and the few.....
I say that you could give the same increase, even on cars equipped with fap...the most important thing ? the car is "carburata" to perfection....not in the case of this car have a file with 3 or more maps lambda...the diesel particulate filter clogs with more fuel when not completely burned..cio? out unburned from the engine...but if the diesel in the most all is burned, the fap behaves exactly the same as the ori...

I 120d 163cv with fap,edc15c35, I started with a 12% and I've done about 15000 miles, then increased to 18% (if I'm not mistaken, but tomorrow in the workshop control) I have done other 50000km and I never had a problem with the fap.Turbo raised 170-180 punti.Chiaramente to low I started with a 4-5% and I interpolated with on 18%.

I forgot to tell you that the only problem that can? give the fap when you map the car heavily ? due to the sensor differential pressure....
if you d? very diesel the turbo to "bounce" tends to increase by only press end the same problem occurs if you overdo it a p? with the press turbo of course....
this factor because of the sensor that detects the pressure difference between before and after the fap for the rise of the press in turbo, and therefore, the exhaust back pressure upstream of the fap is intrepretato from the sensor and from ecu as a blockage that f? starting a forced regeneration....
then the main problem when you map a car ? the diesel s?,because,when this is given with a criterion does not entail any problem, but for a speech of cause-and-effect the problem area and the pressure sensor of the fap....

and can give these increases also with fap? you are not likely to clog the filter more quickly? I thought the machcine with fap as increases were less efficient just not to create problems to ****llo clogging...

you can give but as I wrote above, you should do it in a progressive manner, and that increase is seen only in the higher areas.

so if I understand it,the increase should be given as a percentage, of course, from 10% to 100% load x understand?

thanks a lot!

attention is not a rule and is not the only way,however, the council is 1500 rpm and 50% load.

I'll keep the account,thanks a lot !

But if you remove the fap and better, and the engine ringraziera'
