The ecm takes a reading and compensates the fuel. With the resistor, your ecm is still compensating, it's just thinking it's getting more air. So, it adds fuel. The benefit is, it continues to be dynamic and change injection rate due to altitude, temp, and load etc..

If you would remove the o2 sensor altogether, it would not be able to compensate.

In a nutshell, this device allows the bike to continue to compensate for various situations, but richens up the mixture at the same time.
