Hello,
Yes I understand that there is no gain with modifying the MAP sensor, but it was on the car when I bought it and I do not have the stock replacement at hand. So I will attempt to make it work with this one. Atleast attempt.

Hello,
Well, at least now the Boost PID works as it should. at least almost. Scaling the MAP better and using standard values from a TT 225 hp file helped.
But the problem is still the load request, I request high values in LDRXN and have taken KFMIOP and FKMIRL from a 225 TT file. The last row in KFMIRL is increased to 260 and the last row in KFMIOP is 99.99. but still the load requested is very limited.

Hello, Thank you for the reply, the map in question looked like this when I took the log, now all values are max. I dont think this was limiting, but maybe? I will test with the new maxed map. |

Italian tuning KFLDHBN isn't a great idea (outside of debugging a problem you can't explain, short term)... you should really consider using proper values..

Consider fixing that huge overshoot before turning the boost up.

Well, I plan on exceeding the map limit anyhow, or past 2550 mbar so this map is maybe not so important. Better for now that it is not interfering with the load reached.
Must say that the car is quite booring to drive with 170 in load =( WG-DC is available, it would only be to get it in use. Well ME7.5 has limiters so I guess this is quite a normal problem.

Hello, yes I was considering if I dare show that log here or not. Quite bad overshoot to say the least. But still the tuning for that is also a bit different dependent of the pressure desired, now the requested pressure is very low and close to base boost. |

Hello, That seems to be the answer yes, now requested load is LDRXN. So that is good. But now I started to get fault code 16683/P0299/000665 - Boost Pressure Regulation: Control Range Not Reached with reduced power as result. What is the reason behind that? Any suggestions? |

Hello, Yes it´s attached. After that run i tried to press the trottle again but then the power was already limited. So I guess that 3rd gear pull triggered the fault code. |

1) reduce KFLDIMX
2) bring in LDRXN a bit faster
3) possibly shift Q2 upwards in rpm, maybe increase
4) possibly raise NDLDRAPU

You have massive overboost.

I wonder if Italians are offended by statements like this. lol |

Hello,
Thanks for all the help. I modified the KFLDIMX a couple of times so that helped. It´s not very god yet but better.
Another issue, quite many already listed in this post but I would like to make the car smoother to drive. I understood that the x-axis in KFVPDKSD and KFVPDKSE should be scaled:
(new base boost [bar a])/(old base boost [bar a]) * old value. My question is, can I interprit from the old values what the original cars base boost was?
