In your case it shoud be the LPFP controller!

Why not log low pressure?

My LPFP is OEM and the pressure on the bearish line remains stable between 4.5 to 4.8Bar
When upgrading the HPFP does it need to reduce the pressure in the LPFP? This does not make sense to me ...

No! You don`t understand the fueling system. In case of the controler shut down, it is overheated. Log LP @ time of your problem an see by yourself Wink

Before I draw conclusions see the problem I posted, I reported that I am having problems with high pressure excess, at no time did I say that my LPFP to, I know very well how the supply system works but it seems to me that you do not understand it .
I do not understand why I would overheat the low controller being that I own LPFP OEM and the power of the car is still OEM.
I am injected RS4 and HPFP updated, only after calibrating this step will follow in the other calibrations.

Moving on to leave feedback on my problem.

I was able to solve my problem by studying the VSTMSV, AMSV and HDR functions.
Now my actual pressure follows the requested even at high rotations.
