Coding injectors BMW E91 320d 177 hp

[Alfiuccio]

A greeting to all, I present to you my problem on a bmw e91 320d 177 hp then the ecu edc17cp02 exchange the engine for breaking (N47d20A) with a motor comprarto used in demolition N47d20C.....everything goes smoothly until when I go to encode the injectors.....I tried to fit those of the old engine, but on the bought the injectors do not want to leave.....I tried with different diagnosis but the operation is not successful....from the outset, as errors at startup I have the 4 injectors (activation 1-2-3-4 cyl) sensor, intelligent.....pressure is rising but a lack of time....may be the error that is present that allows the coding? i.e. no dtc to do the encoding? strange, but likely....what do you think?
Thanks to all

Throw them but the injectors are the same as the bosch code?
With what diagnosis you have them made?

[Alfiuccio]

no as the codes are different and change as the model, of course, both bosch.....the n47d20c is the engine type the following at the n47d20a.....I tried with the texa-tecnomotor-delphi

only the bmw diagnosis,you may want to try with inpa or some diagnosis clone bmw

[Alfiuccio]

The thought too...but with clones I don't want to risk it, this morning I tried with delphi and I lost directly the encoding on 1 cyl.....using the tecnomotor I entered the old number of the injector....then the tecnomotor is the encoding, but not the new injectors....service contact marelli and tell me that these injectors are not compatible with my ecu then, not even in the bmw, and it is possible to make encoding (strange)....My question is : when downloading you solve the problem? I have been able to respond....

diagnosis a member of the ago!!!

[Alfiuccio]

Charles I tried with the member but does not allow me the coding of new injectors....update 148 last....magar will be, as they say, to the magneti marelli that it is not possible to perform encoding x compatibility inietori-ecu.....booooo

I did not understand one thing, if you have mounted the old injectors (and then those of the engine that you removed from the car) into the new one taken in demolition, and use the old ecu that you have on the codes that you have them already in the ecu, or you put it on in the ecu of the new engine took in demolition, in this case I know that it does not take them, you made a scodifica?

[Alfiuccio]

Ugo I have not fitted the old injectors on the new motor and the injectors do not come out then I have my ecu with the injectors of the engine, with code most recent....The tecnomotor confirms to me that the encoding can be done with their tool, in fact, after having lost the encoding of the first injector (because delphi) re-encoded with the member by inserting the previous code (the one that was there before).....from here I understood that a member does the coding but not the new injectors....

[ugoboss]

ok now I understand, in this case, it is precisely the non-compatibility between the injectors and the ecu, are not of the same family, and the ecu won't accept them, you had to take the ecu of the new engine and scodificarla .
