	MED17.5 There is a large gap between the actual torque and the requested torque « on: April 02, 2023, 09:16:12 PM »

Can you help me?I calculated and scaled KFMIRL and KFMIOP through the EXCEL table. There is a big gap between the calculated torque and the request, which caused the transmission oil pressure to not be controlled correctly. And there is a big shock phenomenon when upshifting，Replaced the K04 supercharger and upgraded the DQ500 four-wheel drive hardware,Where is my problem?

MDNORM?

Also lower your load, you are running out of MAP sensor range.

Thanks! My request does exceed the maximum range, replace the pressure sensor with a higher range? The load can only be calculated to 2550=191%=400NM? In which module is this calculation in the function manual?
