ASM330LHHTR - inconsistent acceleration results on inclines and declines

We are developing an automotive application that displays vehicle acceleration and deceleration through an LED array. We initially only utilized the accelerometer function of the ASM330LHHTR inertia module but were getting inconsistent results on inclines and declines.  We fused the 3D gyro to help compensate for this inconsistent results  but have been unsuccessful.  Is there an FAE we can speak with to help resolve our issues?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
