I'm sorry, didn't know you were talking about the oil dipstick Dave.

But marko makes a good pt. What's there to trust? It only works when you push the button. Its not constantly drawing power.

tmall explained it perfectly.

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.

Yes. Buells fuel injection is very lean from the factory. The resistor changes the value, causing the ecm to compensate and adds (arbitrary number) 2% to the fuel. The ecm works as normal, takes readings and changes fuel maps on the fly, it's just enriched by X% throughout the closed loop area by changing the signal from the o2 sensor.

Thanks tmall for handling this for me.
