You installed the wrong A/F gauge on car. RSX's from the factory comes with air fuel/lambda sensors (instead of regular O2 sensors) for the front which makes a maximum of 5v, so the a/f gauge you bought was for a car that will produce a maximum of 1.25v which as a result is pegging out your gauge. Buy the right gauge and curb your cheapness, sir.
