Hello all. I'm new here, and hoping somebody can help me out. I have an 02' F4i project that I'm working on. One thing it doesn't have is the ECM / computer box. The bike has an O2 sensor, so I believe it to be a CA model. Does this mean I must find a CA model brain, or will it run ok with any brain? Also, does anybody know what years the ECM would be compatible?

Thanks for any help I can get,
Todd
