Hello. hope this finds you well, I am currently attempting to tune a haltech pro plug in using the closed loop boost control method. the car has a tial ewg 44 mm and a gtx on subaru car. i have 0 P I and D settings and 0 closed loop base duty. target boost is set at 14.7 psi for now. ewg has a 14.5 psi spring. in open loop the car controls the boost as it should. in closed loop the car overshoots the target to 20 psi. remember that all the P I D settings and WG are 0. What am i overlooking?

Can you data log the system and post the lag as a CSV file? If you can, we can look at what the system is doing. The faster the data rate is, the better.

Can you upload your current calibration please?

Hello Andre. Thank you for the reply. What do you mean by current calibration? The P I D settings are all 0 and wastegate is also 0. Will get you a better log asap.

I think he is asking about your Rom, Map...

Yes, the actual map from your ECU. The tune file.
