1999 sti running 10psi?

[Guest]

Hey guys/gals

Got me a 1999 v5 sti, but its only running 10psi. havent done any thing to it and it was imported from japan like that.

Now ive had a few people tell me what to look for or why its happening.. but I don't know too much about cars... (trying to get into it)

Any ideas.. or any one keen to have a look if your in the wellington area?

Cheers!

Matt

Does it still have the restrictor pill in the boost controller line?

Try resetting the ECU and go for a boost.

[Guest]

You were right Boostin! the restrictor has been removed out for the boost controll line. got it looked at on friday.

$200 to get it fixed. stoked as

[wrx_lou]

200 smackers? holey fuck!

[Guest]

Thats cheap, Thats by fitting a bleed valve.. or i could go expensive and buy a electronic boost controller.. but im not rich

[zarnah]

umm... You do know you could just go to a wrecker and buy that complete vacuum line with the restrictor in it for like 10 buks?

my point exactly.

and a bleed valve costs fuckall. wouldnt be hard to setup to factory boost either.

im confused.are you saying you paid $200 to get a restrictor pill removed? thats cruel

[Guest]

Na i havent paid anything yet to get it fixed, i got priced $200 for a bleed valve installed.

Do you reckon i just go to a wrecker?

[Wiretap]

$200 to get a boost tap fitted? I hope that comes with gold plated jousting sticks! just go get the vac lines from a wrecker...

[Guest]

hmm, so a bleed valve is just a boost tap?

lol sweet i just emailed a wrecker for a price.

After all the bollocks i have been through testing boosting issues, i wud question any WRX that runs 10 PSI boost, as it may well be in safe mode

The worst thing is "safe mode" dosent throw a CEL and runs the car really rich.

My car boosts at 10 PSI with no mods, yes there is a problem right, i cud easily fit a boost tap as a work around and get 15 PSI, but the car will still be in safe mode, most likely running rich as well.

So a boost tap wud only mask the problem.

I reckon you should fit a pill and make sure its running 15 PSI stock standard before fitting any boost taps or controllers etc. WIth your boost gauge Youd know straight away if u had 15 or not.

For more serious trouble shooting, when/if the ECU goes into safe mode it makes the duty cycle of the boost solenoid 0%, the best way i have found to test this is to put an LED across the Boost solenoid wires, run it into the cabin and tape on the dash, then watch the LED flash as the ECU dutys it on and off.

If it does not flash, well that means the ECU is not controlling it, meaning possibly its in safe mode for some reason.

Obviously your boost gauge will tell you that you are boosting 10 PSI in safe mode as well, but the LED tells you that its the ECU that is basically turning off boost control. If the LED flashes and you still have 10 PSI, well you rule out the safe mode theory and start looking at other possible causes.

Ok thanks for that,

I was told that I cant actually get a restictor pill in NZ, so they offered a bleed valve.

So best option would be new vac line from a wrecker?

Na, a wrecker will hook you up with a pill.

Just reset your ECU afterwards and go for a drive to see if you get 15 PSI.

[Guest]

Oh sweet I'll have a chat with the wrecker.

Is it hard to put the pill in?
