FI system without O2 sensor, how do I approach it?
My motorcycle - 06 Yamaha R1 - does not have an O2 sensor but it has computer control engine/fuel management system. It has sensors: Intake air temperature, throttle position, atmospheric pressure, crankshaft position, and few others.

Thanks in advance.

You can try treating that pressure sensors with a MAP Enhancer. I think that will do the job for you. It is likely a type of sensor that you can build an inexpensive, yet effective MAP Enhancer for. See this article: http://www.fuelsaver-mpg.com/simple-map-maf-enhancer . It will tell you the 2 types of pressure sensors, and how to tell them apart.
