Stage 1 boost.

[dannyh]

I have stage one map with no other mods and my boost spikes to 22psi and sits about 20psi.
Is this normal for an S3 off boost it sits about -20

Thanks dan

 

[:: blade ::]

Ive heard stage one boost is around 18psi and standard boost is 12psi. I could be wrong tho

 

[dannyh]

Really mine is suppose to be stage 1 but when the car is off the needle sits like this, should it be at 0?

 

[dannyh]

 

[dannyh]

And when the engine is on it sits like this

 

[Machine212]

Yeah while idling it should be a vacuum.

 

[dannyh]

Yes but would it sit that low? And would you expect 22psi spike and to sit around 20 psi ?

My Leon cupra r bam engine was exactly the same as you've posted

Did have an unknown **** map on though, hence why I f***ed it off sharpish

This is suppose to be running Jabbasport

 

[Gary_808]

My buddy had a nice stage one jabba map on his cupra r, very nice boost spike that was probably the cause of a rod exiting the block!

 

[dannyh]

Oh no. Hopefully someone else with a stage 1 map on an S3 can offer some advice I would like to know if it is normal

 

[Machine212]

Im pretty sure 20psi mapped is normal, but ill wait for someone to come and confirm it

Im at 1.2 bar stage 1

 

[dannyh]

1.2 bar is about 18psi
I'm above that. Does you gauge sit below 0 when ignition is off like my photo?

 

[shan00ble]

My guage sits at 0.0 as its an led or digital gauge. Usually round -0.7 at idle.

 

[Jenno007]

That vacuum is identical to my A3 AGU. When the engine is off the gauge should be sitting on the 0, the fact that it isn't would suggest to me that the gauge isn't as accurate as it could be. I originally had a mechanical gauge that didn't sit right on 0 and when I swapped it with a digital stepper gauge it would be right on 0 when the engine was off

 

[dannyh]

Yes, if it is sitting below 0 and then hits 22psi it could actually be 23/24 psi as the gauge is out.
Anyone else with an S3 who can share there readings?

 

[Jenno007]

Maybe do some logging to see what PSI the MAP sensor reads. The gauge could be out either way, +/-.
Sadly I cannot tell you what PSI your car should be running at but I'm sure someone else around here can

22psi is about the limit I'd want to run an S3 at for the sake of the bottom end. 24psi is too much really.

[shan00ble]

I would borrow a gauge and see what it says

 

[s33nyboy12]

Danny have you not just bought this ?

Ask the previous owner if you have.........

Sean

 

[dannyh]

Gonna use vag com at weekend, any Idea what block to measure for PSI?

 

[dannyh]

Yes I have, previous owner got jabba to stage one map it and they reported no issues so presumed it was fine as the boost gage was in at the time so they would have seen that

Rick

oh really,.

what about 27psi..............

Seen a few come thru here with that and more............

way too much indeed
