If you are asking about the RPM/Speed to Gear table, it allows the ECU to calculate what gear you are in so you can use gear based boost control.

Tks for your reply, but I'm asking for the "RPM/SPEED ratio strength" not the table.

Anyone who can explain what does this filter do, I would be grateful.

ratio_filtered = (ratio_filtered * filter_strength + ratio_unfiltered) / (filter_strength + 1);
Attached filter step response graph for strength in range of [0;8]
