I just got a JDM S5 Turbo II motor. Attached to the Wire harness there was this little black box. I think it might be a piggy back. It's say's Rubic LC. I tried searching for it and I keep getting that it's made by Greddy. I'm not really sure what to do with it. It's pretty much plug and play with my factory ecu. Can someone tell me exactly what it does?

 

Rebic LC?

Yea. It's the wierdest thing. My motor also came with different fuel injetors. I don't even know how many cc's they are. I'll post pic's when i get a chance.

 

I used to have that, its for boost cut, and rev limit. Its pretty much like the FCD"fuel cut defencer".
