Thanks a lot.
I have those maps in nice Excel file.
I download this map pack from this forum probably.
Most maps are in those same address like in this excel file or this .pdf from yours link.

About cruise control - till now I thank that it is going to max. drivers wish values.
For ex. when I set speed to 170 km., set pause button, slow down to 110 km and push pause again - acceleration is very fast and aggressive. And it seems like CC want max. driver wish.

I attached 2 files.
One when I accelerate with manual mode (gas pedal push to the floor).
Second when I accelerate in Cruise Control mode.

Control of turbo valve (in % on the records) is different.

So I assume that problem is in one of N75 maps. I found 3 of them but I don't know witch one is connected to Cruise Control mode.

I giving up.
I put old N75 maps, change turbo for smaller boost (max 2350 mbar) and set svbl to 2400.
Now I don't have overboost error.

Hey guys.
I have still small problem with this overboost.
After I reduce boost to max 2350 mbar and set svbl to 2400 mbar it was ok.
But few times I had overboost. First on 3500 RPM when I drove on highway 180 km\h on Cruise Control mode.
It was when car was going to uphill and engine needs more power.

Second time was today when I drove on highway 100 km/h and use manual mode (acceleration pedal) and I slightly push it to speed up.

Could any one take a look to my file and give me a answer what is wrong in this file.

Car has cut off FAP and EGR is turn off.

Hi.
what is wrong in this file - perhaps there is an error?
115mm3_900mg_4000rpm

Remember that there are 2 boost control for different driving condition:
- Eco for boost target map and N75 map
- Sport for boost target map and N75 map

There are some algorithm for "scoring" are you on sport or eco.

Always when activating cruise ecu swapped to use eco maps.

I had optimize mine Sport maps that i use little over boost when driving without cruise. On cruise boost pressure is optimized for economy.

Also there is inverese DW map. 10x10.
It has axels: rpm, iq and output is DW. Scale for Z is *4 so max values on that map area is 25 (25*4=100)
I modified this map and cruise is smooth acceleration.

Some people has think that this 10x10 is SOI limit map, because there is those 25 values.

How did it end?
