QUOTE INCREASING THE BOOST PRESSURE
By adjusting the wastegate linkage the boost can be increased by a few psi. (3-4psi) Shortening the linkage increases the preload on the wastegate spring, hence more pressure is required to open it. I recently increased the boost pressure to 20psi with no adverse effects. You can see the locknut and knurled adjuster in the pic. First, remove the circlip and lift off the linkage Next, hold the shaft with a mole grip whilst turning the locknut clockwise (towards the actuator capsule). The nut may be very tight. Once loose, turn it about 3 turns towards the actuator (about 3mm). Now make the adjustment by screwing the knurled nut towards the locknut until the linkage is against the locknut. Tighten up the locknut. You'll find its now much harder to refit the linkage as you have to compress the spring inside the actuator a bit more. Bleed valves. Some people prefer these, but they offer no advantage and are not very discreet. They are manufactured because they necessary on turbos which do not have an adjustable wastegate linkage. However, if you want more than 3-4psi increase (naughty!) a boost controller is to be recommended, not least because you'll run out adjustment of the wastegate linkage. QUOTE ) CHECKING THE THROTTLE POSITION SENSOR FOR FULL TRAVEL.
Its obvious that if pushing the accelerator to the floor does not cause the TPS to reach maximum travel, the ecu isn't going to receive a request for 100% of the available torque. My second 45, had a lot of free play in the drive by wire throttle cable which is easily adjusted. The cable adjuster can be seen on the left hand side of the TPS bracket. Pull it out of its slot, and screw it towards the end to take up any free play. There should only be a little free play with the pedal up. When the pedal is fully down, the quadrant should be up against its end stop - its just under the heatshield bracket. The lever with the second cable attached is for my ZT50 cruise control. Vreau sa fac chestiile astea doua la mine la masina si desi stiu limba engleza bine m-am cam pierdut in termenii tehnici de aici . Ma poate ajuta cineva? Merci. -------------------- |

Sergiu, pune si tu textul complet, eventual link-ul (pe privat daca nu se poate altfel) si poza de care se vorbeste in text. Am sa incerc eu sa te ajut sa vedem daca reusim. Nu excelez nici eu in termenii strict tehnici dar ma gandesc ca daca ne punem mintea la contributie ne vom dumiri.

cu intarziere, pun linkul: http://45zs.info/Lseries/2545.htm Eu inteleg aproape tot ce scrie acolo, da' nu termenii cheie :angel: La aia ma gandeam ca poate se pricepe careva. -------------------- |

deci Increasing the Boost se refera la cresterea presiunii creata de turbina? -------------------- |

pai tocmai ca tipu zice acolo cum se creste boost pressure-ul cu 3-4 psi fara scule externe. Zice ca trebuie invartit nu stiu ce surub.

E pusa si o poza, da' numa cu zona aia si nu reusesc sa o localizez...asta-i problema -------------------- |

[quote] Manual Boost Controller sau Adjustable Blow Off Valve NU itzi recomand. Potzi sa itzi prajesti motorul foarte usor. Daca totusi vrei sa incerci cu un MBC, itzi recomand calduros un Boost Pressure Gauge...ca sa ai presiunea sub observatzie. Si apoi...cresterea presiunii fara Engine Management...iar e cu dus si intors. Stiu la Subaru ca merge pentru ca avem ECU care "invatza" si se auto-adapteaza la diferitele cerintze, modul de condus al soferului. Ia spune...ECU-ul tau este "destept" si invatza (bazat pe calitatea benzinei, modul cum conduci etc) ? Daca este...poate poate sa incerci...Daca Nu este...atunci recomand calduros sa uitzi despre tuningul asta. @ Skyline Alex - man...semnatura aia a ta...a periculoasa. -------------------- Schumi drive it like you stole it !

Nu stiu cat de destept e ECU-ul meu...exista vreun test de inteligenta?
N-o fi asa destept ca ala de la subaru... -------------------- |

Manual Boost Controller
sau Adjustable Blow Off Valve @ Skyline Alex - man...semnatura aia a ta...a periculoasa.[/quote] nu ai dreptate Blow off valve sau dump valve este acelasi lucru... pe partea cealalta boost controller este cu totul altceva.... blow off-ul este cel care da drumul vacumului din motorul tau turbo cand dai drumul la acceleratie... iar boost controller-ul este cel care decide din vointa ta ce presiune sa vina din suflanta.... asa ca nu este acelasi lucru.... apropo de semnatura... spune-mi ca nu am dreptate.. hehe... in legatura de ECU care invata singur, exista numai pe masini japoneze si nu pe toate din ele... bafta -------------------- Skyline R34 GT-T

surubul despre care este vorba este surubul de la westgate(care este atasat la suflanta masinii)... westgate-ul este ca un "castron" cu capac si intra un surub in el, pe care sunt doua piulite de regula 10mm, iar de surubul acela este vorba.. dar acum nu mai stiu daca trebuie insurubat sau dessurubat... bafta multa ps nu invarti prea mult de el ca omori motorul -------------------- Skyline R34 GT-T

pai nu m-am hotarat inca daca sa fac asta sau nu....doar ca voiam sa stiu cum se face
Despre intinderea cablului de la pedala de acceleratie? Pricepeti de acolo cum se face? La mine se apasa pedala vreo cativa centimetrii in gol, si as vrea sa o fac sa prinda chiar de sus. PS. Hai sa nu transformam si topicul asta in BMW vs. restul. Toti ne iubim masinile, s-o lasam asa -------------------- |

Pai nu am zis ca sint acelasi lucru...unde ai intzeles tu asta ? Ca doar nu am pus EG=AL intre ele ? :bash: Am spus doar ca la o masina turbo este periculos sa te joci cu ele daca nu stii ce faci. Amindoua itzi permit sa te "joci" cu presiunea...blow off valve sa mentzina presiunea...(mai mult timp). iar MBC-ul sa reglezi tu presiunea... Personal sint un "firm believer" in "engine management" facut cu cap de tuneri seriosi cu reputatzie beton. Am access la ei...si de aceea prefer asta...unei solutzii mecanice...periculoase. Da...sint solutzii ieftine...si ofera multzi CP/$$ cheltuit...insa nu e nici pe departe solutzia cea mai sigura. ECU adaptabil exista si pe masinile nemtzesti. In priviintza semnaturii...ma crezi daca itzi spun ca ai dreptate ? Ma crezi insa si daca itzi spun ca sintem in minoritate ? -------------------- Schumi drive it like you stole it !
