wwillym Posted April 6, 2008 Share Posted April 6, 2008 Nu stiu foarte multe despre acest EGR, de aceea formulez urmatoarea intrebare(mai ales pt Dl.Tolin): Dezactivarea temporara a EGR, pe perioada sezonului rece, nu ar ajuta la prevenirea acumularii de depuneri? Adica nu ar favoriza atingerea temperaturii de autocuratire? Scoaterea mufei de la EGR genereaza cod de eroare? Ce consecinte (negative) poate avea deconectarea EGR? Nu dati cu parul... poate ca vorbesc prostii... Am intrebat doar! Link to comment
tolin Posted April 6, 2008 Share Posted April 6, 2008 Sigur ca genereaza cod de eroare, mergi cu MIL aprins. Nu cunosc eventuale consecinte legate de catalizator, deci, nu pot recomanda cu "caldura", in schimb, ai alt motor. Link to comment
ovi_jer Posted April 6, 2008 Share Posted April 6, 2008 Cu ce sa remapezi ? GMDAT n-are o harta pentru benzina romaneasca. Are mape pentru orice tip de benzina si se seteaza din jumperul CO. In romania benzina se vinde sub nume comercial : super,racing,premium,etc. In tarile cu apa calda benzina este de 2 feluri : CO 91 si CO 95. Atita timp cat masina se livreaza setata pe CO95 si in rezervor se baga premium(CO91) sau alta mai scumpa dar la fel de proasta e normal sa apara si problemele ''misfire''. all@Acest subiect este prea stufos si majoritatea informatiilor sau pierdut in off-topic si alte discutii. Revin cu o informatie pe care am scris-o acum 2 ani : http://www.gmclub.ro/forum/index.php?s=&am...st&p=139012 Problemele cu supapele s-au eliminat de mult timp iar daca mai sunt acestea nu se decid cu testerul.

Lucian M Posted April 6, 2008 Share Posted April 6, 2008 OK, si eu- daca bag numai de 95 (care in realitate e de maxim 92 CO)- de unde schimb acel jumper? Macar de curiozitate as incerca. Link to comment
tolin Posted April 6, 2008 Share Posted April 6, 2008 Exista mai multe sisteme de masura: - Research Octane Number (RON); - Motor Octane Number (MON); - Pump Octane Number (PON); - (R+M)/2 CO95 [RON] = C091 [(R+M)/2] "Octane rating has no direct impact on the deflagration (burn) of the air/fuel mixture in the combustion chamber. Other properties of gasoline and engine design account for the manner at which deflagration takes place. In other words, the flame speed of a normally ignited mixture is not directly connected to octane rating." Utilizatorii de Aveo sustin ca nu mai au cablat jumperul de CO, el este sigur prezent la Kalos. Link to comment
ovi_jer Posted April 6, 2008 Share Posted April 6, 2008 Fuel Quality Fuel quality is not a new issue for the automotive industry, but its potential for turning on the Malfunction Indicator Lamp (MIL) with EOBD systems is new. Fuel additives such as "dry gas" and "octane enhancers" may affect the performance of the fuel. If this results in an incomplete combustion or a partial burn, it will set DTC P0300. The Reed Vapor Pressure of the fuel can also create problems in the fuel system, especially during the spring and fall months when severe ambient temperature swings occur. A high Reed Vapor Pressure could show up as a Fuel Trim DTC due to excessive canister loading. High vapor pressures generated in the fuel tank can also affect the Evaporative Emission diagnostic as well. Using fuel with the wrong octane rating for your vehicle may cause driveability problems. Many of the major fuel companies advertise that using "premium" gasoline will improve the performance of your vehicle. Most premium fuels use alcohol to increase the octane rating of the fuel. Although alcohol-enhanced fuels may raise the octane rating, the fuel's ability to turn into vapor in cold temperatures deteriorates. This may affect the starting ability and cold driveability of the engine. Low fuel levels can lead to fuel starvation, lean engine operation, and eventually engine misfire. Link to comment
ASIMO Posted April 6, 2008 Share Posted April 6, 2008 OK, si eu- daca bag numai de 95 (care in realitate e de maxim 92 CO)- de unde schimb acel jumper? Macar de curiozitate as incerca. Uite la Kalos cum arata jumperul : Si uite unde era pus: Eu merg fara el de mai mult de un an... de cand l-a "operat" Ovi. Link to comment
Lucian M Posted April 6, 2008 Share Posted April 6, 2008 (edited) Si- vreo schimbare? Consumul difera? Ceva de reprosat in rest? LE: deci doar se scoate si se pastreaza. La revizii il pun la loc? Edited April 6, 2008 by Lucian M Link to comment
ASIMO Posted April 6, 2008 Share Posted April 6, 2008 (edited) Nu s-a mai aprins in veci "becul galben". Nu mai are balbaieli (pe care le avea cu benizina CO 95 la un moment dat cand statea la turatie constanta - pe undeva pe la 2000RPM... am scris pe undeva pe aici faza, cred), Per total,parerea mea e ca se simte mai bine acum cand ii bag 95. Nu are "zvacul" care ti-l da benzina de 98+, dar acum pot sa bag 95 si sa mearga bine, ce inainte nu se prea putea... La consum... nu stiu ce sa zic, ca am renuntat de mult sa-i fac consumul... Parerea mea e ca jumperul pus te "obliga" sa bagi 98+ ca sa nu ai probleme. LE: Da, la revizii cred ca e bine sa-l pui la loc... Eu am renuntat si la revizii, pentru ca ies mai ieftin si sunt mai sigur pe ce pun in masina, daca fac revizia "in regie proprie". Bine... eu am si avantajul ca stau in acelasi sat cu Ovi ...

Lucian M Posted April 6, 2008 Share Posted April 6, 2008 (edited) Multam! Ramane de vazut cand il operez si eu. Probleme n-am (sper sa nu apara). Azi nu umblu, ca e duminica, dar maine daca am timp vad ce se poate rezolva. LE: cand te mananca- te mananca... L-am scos (cu o surubelnita mica) si l-am bagat in torpedou. A pornit ca de obicei, iar turatia la care a ajuns - cam 1500-1600 rpm. Edited April 6, 2008 by Lucian M Link to comment
tolin Posted April 6, 2008 Share Posted April 6, 2008 Daca nu dai reset la ECM nu se prinde ca ai umblat la jumper. Link to comment
Lucian M Posted April 6, 2008 Share Posted April 6, 2008 Dau si de ala, dar dupa ce fac vreo cativa km (ma duc la socri), sa fie cu motor cald- n-am chef sa stau acum afara pana se incalzeste. Link to comment
tolin Posted April 6, 2008 Share Posted April 6, 2008 Bey, eu am zis reset, nu idle learn ! Si in plus, daca nu faci idle learn la rece inseamna ca ai facut o laba. Link to comment
Lucian M Posted April 6, 2008 Share Posted April 6, 2008 (edited) OK, s-a marcat. Plec afara (pt reset di idle learn, nu pt ce s-ar gandi unii). LE: am dat reset, apoi am urmat pasii pt idle learn. Motorul a pornit extreeem de usor- nu ma asteptam. Acum toarce linistit in curte. LLE: gata, mere excelent. Pornirea e fff usoara. Sa vedem la drum cum se comporta. Revin dupa ora 17.

Abram Burel Posted April 6, 2008 Share Posted April 6, 2008 Buey tolin, ai zis ca nu mai "vorbesti" de idle learn Eu daca n-am jumper inseamna ca sunt pe CO91? Poate d-aia e MILu' ca si cum ar fi ars Link to comment
tolin Posted April 6, 2008 Share Posted April 6, 2008 Ai mufa si n-ai conectorul cu jumper ? Link to comment
zavatecristian Posted April 6, 2008 Share Posted April 6, 2008 Din motiv de ploaie nu merg sa vad existenta si pozitionarea acestuim jumper la al meu aveo 1,4 16v...sper ca exista! oricum o asemenea optiune mi se pare mai buna decat cea a unui octane booster. Link to comment
Lucian M Posted April 6, 2008 Share Posted April 6, 2008 Impresii: pornirile sunt mult mai rapide, mai usoare; parca e mai lenes motorul, insa. Sa vedem cum evolueaza treaba. Link to comment
tolin Posted April 6, 2008 Share Posted April 6, 2008 (edited) ... oricum o asemenea optiune mi se pare mai buna decat cea a unui octane booster. Octane booster nu insemna aditiv pentru cresterea cifrei octanice. Octane = benzina. @Lucian M > corect pana aici, castigi jos si pierzi sus. Edited April 6, 2008 by tolin Link to comment
zavatecristian Posted April 6, 2008 Share Posted April 6, 2008 Octane booster nu insemna aditiv pentru cresterea cifrei octanice. Octane = benzina. Pai atunci de ce pe cutie scrie aditiv cresterea cifrei octanie...in fine:Octane, by definition, is the resistance to burn or detonation. The higher the rating, the slower the burn when ignited during the compression burn cycle of the piston. The higher octane allows for better control of burning for high compression engines. So we want to match the correct octane rating of the gasoline to the engine design to ensure complete burning of the gasoline by the engine for maximum fuel economy and clean emissions. E adevarat ca pe prospect scrie "Removes deposits which tend to cause engine’s octane requirements to rise. After use of product, many engines will accept the regular unleaded gasoline’s more readily without knocking, pinging and after-run'' Link to comment
tolin Posted April 6, 2008 Share Posted April 6, 2008 (edited) Orice aditiv introdus in benzina creste, putin, inevitabil, cifra octanica, dar nu acesta este scopul principal al acestui aditiv. Cu acest aditiv scade sensibil consumul urban, singurul lucru cert remarcat. Edited April 6, 2008 by tolin Link to comment
