I had a lot of headache getting INPA to work, one important tip is to have the USB cable that connects to the OBD port set to COM1 on the windows machine and set latency to 1 ms.

Here are a few tips on adjusting ride height.

1. Once you start lowering or raising it won't stop so be ready to hit the F9 (OFF) button when you reach your target.
2. Each side sort of adjusts together, despite having separate controls the software doesn't let you get too far away from the value of the opposite side before it starts compensating in the same direction. In other words you will have to play with both sides up and down the scale to arrive at a equal levels for both sides.
3. In the previous menu to the one shown, make sure Energy saving mode is off and production mode is on. My understanding is that the settings don't remain in memory unless these modes are set this way.
