Checking What Boost Im On

[GTRAAH]

how do i check what boost im on with this unit?

[NYTSKY]

Any number with - next to it eg: -70

Is vacuum.

A number like this: 124

Is 12.4psi

That is if you have it reading in psi.

i think mine is set to bar... if i was told mine was running around 15 pounds what number should i see if its not set to psi, and which screen do i see it in i changed one of the screens and it says PEAK 1.78 and that = 25 pounds in bar so wtf, how can i be running 25psi no way!!! on the garret -5 turbos all my internals are stock mark at hills said it was set at 15 pounds the last time he touched it and said its healthy that way you wont blow your internals i checked the warning and its set to 1.6 on hi and 1.2 on lo.... IM seriously getting reallllllly dissapointed if im running 25psi Im used to the car FLYING like this but not with this much boost i wanted alot off lee way so when i get my internals done, i can up the boost to 25psi

ACTUALLY 1.6 WARNING SOUNDS MORE LIKE HE DID SET IT TO 15 PSI RIGHT? HOW DO I KNOW IF ITS PSI OR BAR

does it have kpa in the bottom right corner when theres a number displayed or is it blank?

yes it says x100

KPA

It shows that in the warning screen.

I just rang the tuner and he was not there but one of the guys said No wayyy mark would of set it to 23psi.

1.78bar does equal 25psi, so you might want to check with another guage if you dont think that would be right also 1.6 = 23psi

Peak is the highest reading the boost controller has seen if i remember correctly from when i had a Profec B, you can clear it though so you can take it for a quick spin and make sure thats right.

OK so can someone tell me what my boost is on i went through all the screens in hi setting.

Main screen shows this without any boost just on idle

I might have asked a stupid question i just spoke to yavuz at unigroup and he stated that the best way to tell is jump in the car and take off and watch the controller , f*kn hell i didnt know these things were that complicated

pretty sure your set gain has to be around 4ish psi lower then ur desired boost level...urs is on zero?

the last one "peak boost" means ur car has peaked at 1.78 kpa....to reset it go into peak boost menu and hold down the round button until it clears, take the car for a spin, go through all the gears and then check what ur peak boost is again

and change ur display to show psi its much easyier to understand

[GTRAAH]

I will do it when i leave work, just abit scary on these roads with all this power lol

The Profec is really easy to use.

I would first suggest reading through the instruction manual so you understand what each menu means.

For example on the main screen if you rotate the dial one click it will show you what the boost pressure is set to above wastegate spring/actuator pressure. It doesn't appear you have checked this yet. Ie if you rotate the dial and it says 20% it is at 20% above wastegate spring/actuator. This should give you a better idea of what it is set to.

Also I would try changing it from "HI" to "LOW" and then setting the boost pressure to 0% (write down what it was set to before in case it has been setup for a certain pressure) and take it for a spin. It should run on the lowest boost (wastegate/actuator pressure) and then check the peak value to see what you are running.

It really doesn't look like the Profec has been setup much considering the gain is only set to 10% and the set gain is set to 0psi.

LO peaked at around 16psi HI peaked at 21 psi wtf!!

Ok i think i may have figured something out, this is the story after i snapped my gearbox i took it in to get it rebuilt, after a few tweaks and gearbox done the car went harder then it did before so im like how can this happen mark said he just adjusted a few things but didnt touch the boost, NOW previous to all this at the last tune he said he set it to 15psi and it was doing around 316-320awkw so i drove it for ahwile and was happy then one day i decide to change all my intercooler piping and the guy that does my labour noticed one of the hoses was torn so he replaced it all and the car went better then it did after the first tune, So i was happy, then the gearbox broke so on so on..... now i presuming he now has tweaked it alittle more because there is much more airflow coming through because of the hose before, which has now pushed the boost to 21psi without even touching the boost controller is this possible? Is this bad wear and tear for the engine i thought i was doing 316awkw but now id say its more like 350-360awkw . On stock internals Hmmm should i change this. another strange thing is if no one changed the boost controller why would the warning on hi be set to 1.6bar .

no more guessing, get it on a dyno and set it to the desired boost level properly

[JonnoHR31]

regardless of changes since, whoever set it up hasnt done it properly. take it back and ask if they can set the boost again for you
