Can i install a boost guage and controller on the same line????

[JoshsD22]

Hey Guys

I Just purchased a Chip from Chip it, installed and going great. With the package though i recieved a boost controller. I have already got a boost guage fitted from the turbo to the waste gate. When i installed the boost controller now i put in on the waste gate side so that my guage would pick up the boost that is coming out of the turbo. When i went for a test run my guage was reading normal boost at around 15psi

When i unscrewed the boost controller my boost went back to about 13psi.
So logic or as i thought told me to screw the adjustment screw the other way until it showed more boost.

Wrong again i only ended up with the same so i am lost.

Have i installed it wrong.......

Can you have a guage and a controller on the same line.......

If not where do i mount them now..

Any help would be greatly appreciated with this matter.


Cheers

Josh

Hey Josh, I got a boost controller and gauge tpday could you post some pics of where you tee'd the lines too?

 

[RustyNav09]

Would be interested to see install and also feedback on chipit product and ease of installation.

Thanks

did it feel like it pulled harder when you screwed the boost controller in, even though the gauge didn't show an increase? the way you have it set up sounds fine, with the controller down stream of the boost gauge, did you try turning the controller all the way in?

Ideally you shouldnt have any bleeding off in the same circut as a boost gauge.

 

[the_bluester]

What he said ^^^

Aftermarket boost controllers typically work by bleeding air off the line that feeds boost pressure to the wastegate actuator, making it open against it's internal spring pressure. Basically by bleeding air off it makes the actuator see a lower pressure than you actually have in the manifold, delaying when it opens the wastegate and increasing the boost. If you have the boost gauge running off the same line it will also see and show a reduced boost pressure compared to what you actually have.

If the boost gauge tap was right up at the point where you are taking the boost pressure from and the controller is at the other end of a long line it may read close to the actual boost pressure, but you are better off finding another point to take a gauge reading from.

Thanks guys for the information

After some research i realised that this wouldnt work as the guage would read the fudged figures from the controller.

So i need to find another place for the guage. So i have removed the boost controller until then. Can anyone tell me another place for the guage please.

Now to answer some questions

180%JOE: cant show pics because i just pulled it out again.

Rusty: pulls like a train now, it really is awesome. from stock 0-100 in 22-23 seconds to 0-100 in 13 seconds i know its no racecar but thats a big difference. It now loses traction on gravel roads in 2nd and 3rd gear when it hits max boost.

Bods: yeh the boost controller made a huge difference with the chip however i dont really know what boost i was running so i am not going to risk leaving it in until i can put the guage somewhere other than that line.

Has anyone installed a boost guage in another place on a d22 2.5crd your help would be greatly appreciated.

Cheers

I will try and post a photo tomorrow of a fitting I sell that allows you to read boost from any of the rubber boost hoses quite easily and cheaply.
Or you can remove one of the alloy pipes and drill/tap into it for a 1/8th barbed fitting.

Thanks mate that would be good would be interested in getting one if it does the job cheers

Josh

 

[DieselTuner2]

Sorry its taken me so long to get these up.
Takes all of 2 mins to install into any rubber or silicone hose.

 

[Dave]

How much ?

 

[JoshsD22]

Mate looks good would be interested in getting one how much are you looking at and how do i purchase it.

I would be able to put that in one of my intercooler hoses couldn't i ?????

let me know mate cheers

Josh

 

[DieselTuner2]

I sell them for $15 inc postage to anywhere in Aus.

And yes they can be put into an intercooler pipe.

Im working on getting an online shop up and running soon. But for the mean time just phone me at work (07) 3481 2982 or email me on [email protected] with your details.

so this connection would be where we tap into for the gauge or controller? as most controllers come with a t piece attached?

Hello,
It would be easiest to fit the boost controller on the line from turbo to the wastgate actuator. One line form the boost controller (be it a bleed type or Dawes type) must end up at the actuator anyway. If you are going to use the connector shown, run the gauge off that. I've never used one, but personally would be pressure testing the pipe with it fitted to make sure it has sealed well.

The gauge issue is one reason I prefer the Dawes type ball and spring controller, as it doesn't bleed any boost until it opens and sends the pressure to the wastegate actuator. This allows you to run a fairly accurate gauge off the same line if reguired. Elctronic boost controllers will not 'bleed' any pressure either.

Cheers.

Hey everyone i just installed a boost gauge on my zd30 d22 i put the t-piece for the boost line that goes to the gauge inbetween the pipe that comes directly off the turbo intake side to the engine and the sensor thats bolted to that pipe, is this the right place to put it or is there a better place to put the boost gauge t-piece?
Cheers

 

[tweak'e]

thats fine

 

[BP90]

Cheers tweake, only asking as my gauge reads up to about 14.5 at full go and i heard others said it was meant to be about 15psi so just wondered if the place where you t it into would make the reading vary by a few psi. Thanks anyways tweake

 

[180%JOE]

That's exactly where I installed my boost gauge and mine reads 15psi. That was until I boosted it to 18psi
