Hi all
2l tfsi,we put K04,Injectors from S3 and autotech hpfp, now it was very hard to calibrate the westgate as at the start we had huge overboost, so after serval runs i manage to tune it too 1.5Bar all perfect, now as i requast load from 190 and now 220 , on high revs car cut and requast boost drop too 600 or similar numbers, are we missing something here why cant get requast 1.8bar, when we requast 1.4 bar and then we have overboost with westgate it doesnt cut, but if we just change the requast to 220 its start cut in high revs with low boost requast.
You can see on V3 all ok on 1.5 boost, V5 we just change requast and ldrxn,
I attached log+files,
Will be glad for some help.

You'll never be able to request more than 1.55bar via calibration only, ever.
You have throttle intervention around 5k, but there could be torque intervention happening way before that.
Have you logged Timing Retard? If you've got excessive timing correction, the ECU could be pulling load.

Going to mention what you did to get it working @ 1.8 bar? Upgrade the map sensor yet? |

Why are you not asking why there is throttle cut?

The wiki suggests several possible reasons for throttle cut. You can't spot one offhand that applies to your log? If i had to guess, positive deviation. Not sure why you didn't throw a code. |

Why on earth would you mod the delta instead of fixing the root cause, which is positive boost deviation? Fix that first. |
