Consum mare sau normal e46 nfl


Recommended Posts

Pt curajosi si nelimitati zici... Sa inteleg ca EGR off din soft?

Eu de cand am obturat EGR consuma mai mult umpic, presupun ca din cauza ca ECU asteapta aerul de la EGR care nu mai vine. De aceea te intreb daca l-ai anulat soft.

Exact, din soft, si trebuie compensat cu mai mult avans in acea zona. Ca si studiu de caz, gasit pe net cu masuratori exacte facute de o universitate, cuplul de cruising normal e undeva la 100 NM pentru un diesel de 1.9/2.0, marind avansul cu 3-5 grade acesta urca la 112 - 115 NM, de-aici => less pedal and less fuel for same rpm. Masuratorile au fost facute si pe dyno.

Ma refer la avansul dynamic din soft nu static. Pompa VP44 are o 'fereastra' de 22 grade in care avansul dynamic ajutat de injectorul cu fir poate sa oscileze. De ex -1.5(idle) to 16(blana) astea-s valorile stock, e un range de 17.5 grade.

La o resoftare urc pana pe la 18 grade => +2 grade avans pe dyno aduc in plus aprox 4-5 cp la motorul de 136 cp

 

Am facut doua print-screenuri la cum modific eu mapele, ce mape modific la un remap, EGR off avans etc.

Din poze va puteti face o idee despre diferentele de avans cu si fara EGR. Consum ultimul weekend, viteza legala, masurat la pompa 4.2 /100km, fara depasiri, localitate 60 65, afara 80-100.
