Vehicle Engine Audio System WIP

Hello Everyone!

I am developing Engine Sound System based on UE4 Advanced Vehicle.

I record my brother Toyota Auris engine sound with two mics. I record 4 to 5 speeds of the engine on 4 gears. So I got about 20 loop sounds.
I already have different sounds on every gear. But I want to incorporate much more:
Here is the video where I explain everything:https://youtube.com/watch?v=04Kj2eN2_V0
Default UE4 Engine sound is connected only to motor rotation. I want to connect it to vehicle speed, is he going straight or turning, slowing down or accelerate. Is he in the air, etc.
I will update on my progress.
