Glad all is well with you Kelu, stay safe my friend.

Kelu's trip home could turn out to be a modern version of the movie Planes Trains and Automobiles.

[Critterman]

Yes it could SA.

 Kelu,  Let us know how it went.

[Kelu]

Trip home was kind of fast and smooth. Started at 4am as passenger in the car up to Frankfurt took under 4h. I was expecting controls at the 2 borders (through Holland) because one of the terrorist escaped yesterday but was not the case. Waited about 1h until the ticketing office opened, during this hour the checking hall was closed by the police (ssst, wife doesn't know about this) but seemed to be a false alarm. When this happened I started to be irritated because I thought I will not be able to reach home today, security measures were very high, police patrols with dogs all over, security and police cars with sirens on every 2 minutes in the airport area.

They changed my ticket, during this 15-20 minutes about 4-6 airport employees were operating a computer to change my reservation and they kept looking at me with strange eyes, I didn't care, I just wanted my ticket to be able to depart withing 2h.

After this all went ok, arrived home in afternoon.

Tomorrow I have appointment to a Peugeot dealership to check the issue with boost control Saturday or Sunday mow the lawn and maybe a bbq. 

[Critterman]

Glad you got home safe and sound

[Gentleman Jack]

Bbq?
Chicken?

[Sol Asylum]

Porc

[Kelu]

Glad you got home safe and sound

safe and sound? :/

GJ: for me the best chicken meat is the porc meat

[Critterman]

Not sound of mind for sure, but all in one piece with out damage

[Gentleman Jack]

Porc is derishish

[elff]

And good protection from terrorists.

[Sol Asylum]

It's better than Crappy fish, I can tell you.

[elff]

[Critterman]

What you don't like fish with the head on it?

[Kelu]

Porc is derishish

I love the romanians, you should try them 

And good protection from terrorists.

Yeah, I eat pork and drink alcohol => 100% not terrorist 

It's better than Crappy fish, I can tell you.

Golden rule: stick with the basics but nooo, you wanted fish in a traditional restaurant, of course you got crap (this is the romanian word for carp) 

[Sol Asylum]

That's the last time I trust you to help me pick out something on a menu in Romanian.

[Kelu]

Back to topic or I will report you.

I owe you some photos from last week.

GTR for elff (I have said hello to the greek tuner team):

The engine was under rebuilding in a new configuration.


Dyno graphs - this is with wastegate spring maximum 1-1.1bar (14.5-16.5psi) above 4500rpm:
[attachimg=5]

[attachimg=6]
The torque is on Nm and values are estimated at the crank, not wheels. The car feels perfect for normal drive in the city, I love that flat long tq curve, I'm happy I could reach V8 kind of configuration for daily driving.

My aim for this dyno was to check if knock retard has disappeared after I clocked the sensors and changed the spark plugs, and seems that is gone at this boost level:

[attachimg=8]

At the top end a little bit of KR appears after 2-3 pulls, which confirms it is still working  only on cyl3&4 (check the table under the graph) which I don't consider dangerous because is only at top end and only 2.2 degrees.
Also I'm happy lamnda stays very constant for whole rpm range between 0.8 to 0.82.
