Prior to taking position I had a brief conversation with my FLM stating that a few airplanes might go through final as I haven't worked with this equipment on arrival. I was told that I wouldn't be the first one today jokingly; I began my monitoring and eventually took the position. I had the opportunity to work a couple of approaches before I observed my tab list filling up and I recognized I was going to be busy. I set up my MULT R; my history trails and my presentation to ease in my IFR turn-ons that I haven't worked in a while and began working the scenario. After my first few turn-ons I recognized that everybody was going through final; but I was comfortable because I had altitude. Naturally started slowing other aircraft and implementing tools that I figured would help me as I had several more airplanes coming fast. I ended up breaking off a couple of aircraft on final; so I could get everyone under control and execute a safer plan that would get everyone down. It was not pretty at all; I was at this time not at all comfortable with the presentation of FUSION; but was scared to try and switch back to Site 1 though I do recall one aircraft I believe at four thousand west of final at the same altitude and I had to make an adjustment vector to ensure separation. The problems in this scenario happened because I was not able to interpret the display correctly versus real time in STARS. My FLM was doing administrative duties I believe until he heard the change in my voice. He came over and monitored as I struggled to get everyone in good position and on the ground. I had not at all been notified by anyone that worked in the operation or on the second floor that I had a loss or any type of deviation. I did not recall any errors or losses so I figured it was a major learning experience. The following day on my way home I was made aware of an investigation by the ATM. I came home filed for an extension and here it is. Recommendation; training in a timely manner; that is consistent with what to expect; and not just checking a box stating that training was given; or lumping it with some other training. The extreme difference in presentation of FUSION versus real time presentation of STARS should be explained in training.
MCI Controller described his/her first session with FUSION RADAR and noted the difficulty and unfamiliarity with the characteristics especially reference turn on vector assignments.  Reporter suggested additional training be provided.
