La Reno nu se calculeaza distanta dupa timpii de injectie ca la VW.

Si Reno asta, e varf de tehnologie?

Poftim, ca sa nu crapi de ras:

QUOTE(mail de la Ross Tech)

Yes, that is also what the spec sheet for these control modules say.

If your friends work in an area like that I do believe the should have
access to such documents or need to talk to their supplier (i.e. Bosch)
for that matter. wink.gif
It's not really a big discussion anymore from our perspective, the
knowledge around this has been around for the better part of 10 years so
I do believe that it is well understood by now and the error rate (in
terms of tools reading proper values) is quite small.

Zice si de integrala din timpii de injectie si sursele multiple?

Extra:

viteza afisata = viteza reala (CAN) + 1,5% + 4Km/h
viteza afisata = viteza reala (CAN) + 1,5% + 5Km/h
viteza afisata = viteza reala (CAN) + 1,5% + 6Km/h
viteza afisata = viteza reala (CAN) + 6,5%

Care sunt palierele de viteza pentru care sunt aplicate respectivele formule si cine transmite pe can viteza?

Alea-s glumele voastre de autobaza. Ia sa citam din ce au dat altii quote:

QUOTE(post sters de-al meu @ citat de alt "specialist")
Kilometrii din ECU sunt estimati pe baza timpilor de deschidere ai injectoarelor si alte variabile


Unde scrie "integrala din timpii de injectie"? Aia ai inventat-o tu. In rest, "surse multiple"?

QUOTE(IRONICK @ 27 Feb 2012, 12:00)
Iti amintesti intr-un post mai vechi ca am spus ca sunt doua surse?
*



Da, gasim kilometrajul in calculatorul de ABS, in cluster (km sunt stocati in 3 zone diferite), in ECU si probabil mai sunt si altele.

Imi pare rau, eu n-am acces la documentatia Renault.

Bottom line, kilometrajul stocat in ECU-urile EDC-15/16/17 de la VW este obtinut prin integrarea vitezei functie de timp. De unde vine viteza aia? Irelevant, este un parametru (as in "si alte variabile") pe care ECU il foloseste.

pina una alta lamuriti-ma si pe mine de ce toate motoarele benzinare de la PSA au senzor de turatie pe volanta + senzor de pozitie axa cu came pentru referinta si numai TU5JP4 are un singur senzor turatie/referinta pe volanta?

Cine ofera 5 impulsuri pe metru? Sau la viteza de 1.75km/h ce se intampla? De la cate roti calculeaza viteza (nu se calculeaza de la toate 4)?

@bucatzel: 3 zone numai in cluster. Mai sunt si chestii de gen "din 2 in 2 km, valoare para sau impara".

Inca unu'. De ce nu incercati si pe topicul cu basescu? Sau pe ala de fotbal, sa va egzplice tonies cum e la maibah.

Io unu' deja ma improsc de ras, sincer... Ma gandesc ca urmeaza sa puneti bancuri la probleme tehnice, bule la imbunatiri, samd.

cu un singur senzor pe volanta la pornire da scanteie la intamplare practic pana porneste, cu inca un senzor de pozitie pe axa cu came stie exact la care cilindru trebuie data. eu asa stiu

hai ca am aflat, ECU de pe tu5jp4 e mai destept, foloseste o smecherie la care-i zice DEPHIA = "Détection de Phase Intégrée à l'Allumage", afla daca cilindrul 1 e in compresie sau nu functie de tensiunea necesara pentru arc la bujie (e mai mare daca cilindrul e in compresie) si de aia nu mai are nevoie de senzor de pozitie.

partea nasoala e ca atunci s-ar putea sa nu scap doar cu senzor volanta ci sa schimb si modulul de aprindere.

da' oricum, chizdofrenica gaselnita, chiar ma gindeam azi cum dracu'-si sincronizeaza asta aprinderea fara senzor de pozitie.

Ce sa-i faci musiu IRONICK, mai ajungi si la bula cand debitezi asemenea minuni.

Rusine sa le fie inginerilor de la FauVe ca nu s-or consultat cu asemenea autoritate in materie precum dumneata ! Rusinica !

E o pla corectă. A uitat că sustinea ineptii cu distanță parcursă functie de timpii de injectie, iar acum o dă la întors cu senzorii de abs...

Tui mama ei de bula.
Amu' mi s-o rupt pana acum de faza, da' deja pesemne ca m-ati exasperat, de ajung sa-mi dau cu parerea.

Din timpii de injectie ar trebui sa stii turatia, nu?. Nenorocitul ala de vag mai are si prostul obicei sa stie si-n ce treapta esti (si sa-ti dea tot felul de sugestii tampe, cum ar fi sa bagi a 5-a la 60 km/h, dar sa nu divagam), deci din astea doua cred ca ar trebui sa poti afla si km parcursi, ca doar ii o amarata de inmultire. Amu' exact-exact cum intra in calcul perioada cat masina sta la punctul mort nu stiu, da' nu mi se pare deloc de necrezut ca s-o gandit cineva la asa ceva.
Parca vad ca vreun desteptovici care cand i s-o spus de punctul mort, el o auzit doar "division by zero" tongue.gif

@ kum. Discutia aiasta o inceput pe la jurnal de bord. posesorul jurnalului o facut curat, asa ca s-au mutat la ... tin-te bine, la "un banc". Intre timp, au ajuns aici. In continuare, io astept sa faca o vizita discutia asta si pe la topicul de fotbal, sau pe ala cu basescu, sa duca la maxim confuzia.
