Does the ECU have learning capabilities?

I have a 02 GSXR 1000 with cams, ported head, exhaust and your modified ECU. Does the ECU have learning capabilities? My bike doesn’t have an O2 sensor, but I have been told I don’t need to use my power commander, my computer will tune it self.

Nothing could be further from the truth. Your stock ECU contains mapping to match the stock combination. If you do anything to increase intake or exhaust flow, you will need mapping to obtain the proper air-fuel ratio. Does this mean that your bike will not run without one? No, but it will accelerate much harder with one. Your stock ECU is not self-mapping (new bikes with O2 sensors are for emissions only and must be removed for proper race performance).
