Am făcut vreo 150 km ieri cu monitorizare continua și ECU jonglează īntre closed și open loop. Ba intra ambele bank uri īn open loop, ba stau amāndouă īn closed, ba bank 1 rămāne īn closed și bank 2 intra īn open, pe perioade consistente de timp de ordinul zecilor de minute... Foarte ciudat.
Nu e prima oară cānd folosesc aditivul asta, ar curios sa fie de la el, dar nu exclud nimic. E vorba de Oxicat, de la Pro-tec.
O sa pun INPA azi sa vedem dacă obțin aceleași date ca și cu testerul BT. Ce mi se mai pare ciudat e ca deși STFT urile sunt la 27% pe perioade lungi de timp, LTFT nu s-au modificat de la 0% constant. Știu ca valori mari ale ST pe intervale lungi determina ajustarea LT pentru a minimiza diferența dintre ele, dar acum pauză.

O sa mai iau o dată la verificat furtunurile și zonele din care ar putea trage aer fals, ma mai plimb sa termin benzina cu aditiv și cred ca totuși ar fi utila și schimbarea sondelor, le cam ajunge 340.000 km smile.gif. Am găsit un magazin la BV care are preț f bun, 166 lei vs minim 224 īn rest.

Am facut asta:
https://vimeo.com/485122318
https://vimeo.com/485121653 - aici se aude un pic exagerat pentru ca pedala era apasata repetitiv, rapid

Nu am gasit niciun fel de gaura/crapatura in furtune/admisie, fasaitul asta pare sa vina din zona DISA.
Am desfacut-o si am verificat garnitura de pe admisie, am mai strans axul care tine clapeta, pare in regula. Nu imi dau seama daca sunetul e normal, stiu ca l-am avut dintotdeauna , desi e eronat descris ca fiind pe decelerare.

Sunt curios daca tu il ai, Bart. Apare cand motorul e la ralanti si pisti doar un pic acceleratia... Daca intr-adevar trage aer fals pe undeva, ma gandesc ca ar trebui sa creasca si sunetul odata cu rpm... ?!

The hissing sound is absolutely normal. Engine is sucking air through idle control valve and throttle body. But, what isn't normal in all m54 is WHY the hell engine comp isn't adding more fuel right when you touch the pedal. That's why you hear this sound b/c engine is waiting for fuel, just half a second when RPM aren't growing - but they should!!! - Like in other non bmw cars. I have M54B25 - I know what I'm talking about. It really pissing me off!

There is everything in best order with this engine. The hissing comes from the ICV and is nothing to be worried about.

Da, se aude cum trage aer prin icv ceva.
Nu merge link cu sonda, dar pune Bosch ca cele originale.
Zicea Bosch că țin 170.000km sau ceva deci daca sunt cele originale īși au trăit viața.

absolut normal zgomotul, asa facea si al meu, interesant era ca la mine daca acceleram usor de cateva ori se opera motorul practic apasam pedala 1mm sa zicem, dar eu aveam si modulul ala la pedala.

Da, sunt BOSCH sondele, luate pe cod.

Tind sa cred ca aditivul a stricat ceva, am mai măsurat ieri și sondele dau semnal foarte slab de pana īn 0,04V max, dar nu tot timpul.
Pare ca temperatura mai ridicata decāt normal (ceea ce face aditivul) sau diferite depuneri tot din aditivi pot influenta / strica sondele.
Așa că o să aștept sa termin benzina actuala și vedem cum se comporta apoi sondele vechi, dacă īși revin ușor ușor. Oricum le schimb dar sa nu le stric și pe cele noi cu benzina actuala.

Sa nu cumva masori rezistenta pe sonda, se poate strica. Doar elementul de incalzire se poate masura asa, senzor oxigen doar cu voltmetru cu impedanta mare.

Știu, măsurarea la care m am referit sus era cea citita prin OBD.
Thx
