Hi,
I would like to know if the Sparkfun MPU9250 products would solve the problem I'm having, as follows.
I've been using an MPU6050 (3 axis gyro, 3 axis accel, with the built in motion filter called DMP) on a car axle to measure axle angle when driving. On a long banked corner (2 degrees) the sensor reads 0 degrees while moving (~40km/hr), but when stopped on the corner it reads correctly (2 degrees). The physical axle angle is the same though in both scenarios.
I believe the lateral force from going through the corner when moving is affecting the sensors interpretation of which way gravity is, and is adjusting the roll angles accordingly. See image;

Given that the Sparkfun MPU9250 sensors have a built in magnetometer and/or use a Kalman filter, will these fix the above issue?
Time is a critical factor at the moment in my project.
Thanks in advance for your input.
