Pitch has little to no impact on stability control. Stability controls job is to control lateral movement. Assuming all four tires are on the ground, the system can monitor slides based on wheel speed, steering angle and yaw. The pitch sensor, if tied to anything beyond HSA, would probably get in the way on hard acceleration. Hard acceleration on a slight incline would make the car think its flipping backwards. Can you imagine ST trying to fix that. Lol
