What Does Your Q45 Afm Read At Idle?

[dangerman4]

can someone who has a q45 AFM and a PFC please go out and start your car and tell me what the voltage is at idle?

thank's heaps in advance.

[paulr33]

the mafia has one

[paulr33]

is yours really high or something ?

[dangerman4]

is yours really high or something ?

well yes...

look who is asking the question.

im trying to problem solve why im getting a reading of 2.4volts at idle.

you said the other day that it should be below 1v at idle.

[paulr33]

yeah off the bat 2.4 seems way too high

i'd be suprised if it was correct

if you rev it a few times

does it always go back to the same value?

are u sure q45 is selected?

no pipework leaks around the afm?

whats the voltage with the car set to ON but not running

[paulr33]

a photo of SENSOR SW / CHECK with the car set to ON but not running and another pic of the car running, that shoud help. also confirm what is under SETTING, AIRFLOW

ingnition only = .160v

it starts around .350v then counts down.

when running its up in the low 2.2 - 2.4 volt range

PFC under AFM is on vh41

[dangerman4]

if i try to bounce the revs up and down it seems to get higher every time it drops back to idle

Where are you located. If your in SEQ I would be more than happy for you to test another unit to check values.

[paulr33]

clean the afm, sounds dirty

[dangerman4]

would being dirty cause it to be fine to 317kw one day and not even idle the next day?

im heading down the street so i will grab some contact cleener and give it a whirl.

[kudos.motorsports]

Are you using a dry or oiled filter?

[paulr33]

well, the idle will be shagged if its saying 2.4v of AIRFLOW to the powerfc and there actually is jack all. its probably on half the load axis at idle. ie because its saying 2.4v on the load axis, its like halfway. it would be mega sucky idle, suprised it even runs

[dangerman4]

ive given it a good blast with contact cleaner..

waited half an hour as the can says and only a slight improvement.

1.8 volts.

once i reved it a couple of times it went back over 2 volts.

[paulr33]

what pfc (ETC, PROG VERSION)

what intake piping (stock turbo duct?, custom?)

what air filter (pod, box, panel filter, open mouth?)

where is the afm (in front of turbo, after intercooler?)

can u get a photo of SENSOR SW / CHECK with car running

do u have someone local with a knock working q45 AFM ?

can u try the stock afm back on it ? does it give similar readings?
