What does this mean? (It'll probably take a Japanese person to answer this)

Hi everyone ^^ I'm new to this forum... and I'm suprised there was a board like this so I decided to make this topic. I was watching a Japanese video on YouTube made by Melancholy of Haruhi fans whose voice sounds like the cast, and I really liked a part of the video which is about Yuki, and a remixed part of the song Uninstall (Bokurano OP), and I looked at the lyrics and typed them up on my computer, but I couldn't understand some of it (even though I'm half-japanese.....)

Well this is the sentence:

異時間同位体と同期する力　今の自分には必要がない　私が自由に動く　その為に　余計な力は

i cant understand that first bit.... (btw i removed the bits that say 'Uninstall' in katakana)

[Soulshift]

異時間同位体と同期する力　今の自分には必要がない　私が自由に動く　その為に　余計な力は

i cant understand that first bit....

Breaking it down:

異時間＝alternate time (line)
同位=same status (position)
体=body
同期する=to synchronize
力=ability

i.e. (I currently do not need) the ability to synchronize (myself) with an/the alternate time-line version (of myself)
