Hands on with TSP's Stage 1 tune for the 1.5T (non-Si)

[gtman]

So, i will have a cut of power only. It's right?

Basically yes, that's all. If you monitor knock control and see it rise to 1.0, make sure you back off on aggressive driving until it drops back down.

You're welcome to upload a log here as a .zip and I'll check it out if you're concerned.

Well KC is there to protect the engine.
Above 5300rpm it will retard ignition by 6.5 degrees. If KC goes above 0.7 it will remove a little more, up to 8 degrees or so. This will be mostly proactive retard just as a precaution.
But getting as high as 1+ and probably removing 12 or more degrees of ignition is a good sign that it actually detected knock. KC will most probably keep your engine safe, but it is better to avoid knock than have your ECU remove it imho

Personal opinion: a nicely built tune should not require a lot of backing off. Imagine not having a V2 or tuner view active... ?

For sure if it lands in 1.0 in just a pull or two it detected real knock. But the rise is so heavy because it also rise with the RPM. I use to change at 5500 or so, almost never change at redline.

A 3rd + 4th WOT pull, with warm weather changing gear up to the rev limiter will make it easily land in 0.7 to 1.0 territory..

I live in Greece, so ambient temperatures are not at all different to yours and .75 is the most i see even when pulling 100-200, (so 3rd 4th 5th)
Just saying...

This is my log of four weeks ago, with limit boos to 21 psi: high value knock control there is with 16,5 and 19 psi setting also.

Knock is common even on stock tune, you can't account for every possible scenario. For sure you can minimize it with a custom tune. Tho as I said, if you dont change at redline and use an intercooler (and make sure the air filter is clean so the turbo isn't working harder) the knock control rise will be minimal.

At which RPM you change gear?

At which RPM you change gear?

6400-6700 depending on gear.
I make max whp until 6400 so I tend to rev it a bit

SilverArrow...

So here's the thing. I did a quick look at your log and it's kind of understandable that knock control rose to 1.0 at a point ...

You were pushing it REALLY hard. Matter of fact, you had nearly 10 hard pulls in a matter of 7-8 minutes. Other than that, I didn't see any problems/issues show up in the log.

Here's a screen from the 5:03 mark after you had been going in "race car mode" for a while :

 

[SilverArrow]

For "race car mode" i mean a race on the track: however, it does not seem to me to be my case.

I will try to change the air filter also.

Thank you very much Gtman

The log says the first rise was after a few pulls, it first jumps to 0.6x and then to 0.9x with the intercooler at 50 ºC (heatsoaked, temperature raised very fast), very common. I use to see my after intercooler temps 5 to 10 degrees (celsius) over ambient (mishimoto FMIC) and k.control stays at 0.49 all the time except when ambient temp is too hot, idle heatsoaked or change gear past 5300 RPM.

Just check it and make sure it is not clogged.

So is it a fair assessment here is that he has an overactive knock control due to his intake air temperatures being too hot? And that to resolve this he can upgrade his intercooler but in the meantime, don't run the car too hard back to back with the stock intercooler?

**I am at work at the moment so can't look at the log.**

I think hot air is causing some knock, that's expected.

Just back up a bit untill things get cooler. If you are really serious at it and want more performance for longer go buy an aftermarket intercooler, I recommend it but it's expensive so make sure that's what you want.

6400-6700 a seconda dell'ingranaggio.
Faccio il massimo whp fino a 6400, quindi tendo a fargli girare un po '

BBuahahhahaha. Always??
