Tā kā nezinu kas būtu, ja nebūtu gala bundulis, bet nu kko jāpadara lietas labā.

arwolc rakstīja:help.. manam 1.9tdi slēdzas kkas nost pie 120km/h, ātrāk baig negribīgi iet,jo pazūd spiediens turbīnai! vakuuma rores visas skatījos, vārsts ar iktā šansē[ar testeri pamēģināju ] kas varēt būt par vainu? kompī met kļūdu par Manifold Control difference!
a kā darbojas tas wastegate šitam? tas vnk atgāzes nelaiž visas uz turbīnu,bet laiž, apejot turbīnu, izplūdē??
P.S cik reāli izmaksā uzstādīt čipu MK3 1.9TDI?

N75 Vai vakuuma trubinjas pie vinja. Vinjsh straadaa impulsu rezhiimaa, taapat fig paarbaudiisi...
The N75 is the valve that plays a large part in regulating the wastegate. An unenergized solenoid (0% duty cycle) permits full charge pressure on actuator diaphragm. So the turbocharger naturally regulates itself. As boost builds, the wastegate opens. The ECU can operate the N75 to vent some of this pressure so the wastegate either does not open, or opens less. For example if reading is 62.8% duty cycle it means over a 100 millisecond period (1/10 of a second) the charge pressure in the actuator line was filled for 37.2 milliseconds and vented for 62.8 milliseconds. An orifice in the charge pressure connection restricts the flow rate of charge air into the actuator system. If you are seeing a large difference between the two reading off block 115 (request high, actual low), and you see that duty cycle on the N75 is high (90-100% range), then you are probably leaking boost from a pressure hose (turbo outlet to intake manifold) or the diverter valve (DV). You should then check all clamps and hoses along the whole pressured tract as well as swap DVs.
So, when we look at, let's say, log 115 and see that actual boost is less than requested boost while ECU is yelling "somebody close that f%cking wastegate!" (N75 duty cycle close to 99%), we know there is a problem: either there is a boost leak, or the wastegate is not closing all the way (stuck).
