So i got my stage 3 in my ‘13 MCS and she is smoking but in talking to Mario i maybe have a vacuum leak.
some “blup blup” sounds/feeling and loping at certain times when idling. Also picking up either a normal vibration or new vibration around 2200 rpm when parked and holding that RPM. It’s very subtle but its not there, then there around 2200rpm then gone after that.

can the schwaben tool log boost levels or live display boost levels?
i have seen quite a write up from a couple of guys about logging and it wasn’t simple, but i know they did it.
i purchased dashcommand and going to grab an OBDLink MX or MX+ but until then i want to see what the boost levels are and with the OBDLink will be able to do the 4th gear pull to redline for Mario so he can see my logs and decipher what’s happening.

boost is now “holy **** now that’s boost!!” and not,, that’s cool its a turbo... but Mario thinks its possible we need to adjust the wastegate on the new JCW Turbo i had put in it. The OBDLink is best but i for my own peace of mind want to log if possible, with the schwaben, some boost levels

 

Do yourself a favor and get a real boost gauge. All of the tools and apps you mention pull boost data from the OBDII. Your car's MAP sensor cannot read anything above 22.4 PSI of boost. It is possible that you are boosting beyond 22.4 and do not know it. Something as simple as a mechanical boost gauge will save you thousands of dollars on an engine rebuild.

I was pushing upwards of 26 PSI when I installed my new turbo. The OBDII sensors only showed 22.4. If I had not installed a real gauge years ago, I would have been pulling 26 or more PSI, been totally unaware and would have eventually blown a motor. Also, If you haven't done it already, replace your connecting rod bolts with APR.

 

i am 100% heading that way.
for now on my old android phone and old bluetooth obdII reader that wont work on my iphone Torque is pulling the attached logs.
i have highlighted in red a couple of the 4th gear pulls.
the last one should be the 100+ mph, 5500rpm pull.
but the boost is maxing instantly, there is no delay or climb to max boost in the logs which bothers me.

but yes, 100% a gauge is in my short term future.

 

I'm willing to bet that the 22.7 you are seeing is lower than what is actually being pushed through. You should not push the car until you get an actual gauge so that you can actually see what is going on. It may hold it for now, but without upgraded internals, it will eventually kill the motor. Flooring it or pushing the turbo right now is a roll of the dice.

That being said, if you are cruising and slam the throttle to the floor, the turbo is going to attempt to reach the boost target that the DME is giving it as quickly as possible. Based on your throttle input, the rapid build to max that you are seeing in your logs is normal.

Totally unrelated photo of a BSH dual boost tap on an N18 intake manifold...

 

thanks a million scotty i appreciate your input more than the silence i am getting from......well we'll leave it at that.
interesting approach on the unused intake port, i like that idea. thanks for clarifying that it fits the n18, mine is a late 2012 aka 2013.

 

Scotty, can you recommend a boost gauge for a N18 R56 MCS hatch.

 

I use a Stack gauge. It is mounted into an Alta gauge pod on the side of the tachometer. I'm pretty happy with it.

 

Thanks Scotty, but what about the engine side. Where did you tap into and is there a kit?

 

Thanks Scotty, I found the N18 tap kit.
