Change the gravity force in Unreal Engine but not affecting to Airsim IMU

[Charles-Lim93]

Hello,

I'm making Lunar exploration simulator with Airsim Car mode and making navigation system for space car.

I want to get IMU's z axis accelerometer data (which is gravitational force) as 1/6 of Earth's gravitational force.

So I changed the global Z gravity from -980 to -160 in World Settings (UE 4.27),

But when I read IMU data from airsim, it still shows -9.81 m/s^2.

Is there anyone can give me solution?

Thank you in advance.

MY VERSION===
UE = 4.27
Airsim = 1.08
