okay guys so i baught my car, with this ecu piggyback thing, it has no name, brand. etc. etc.

said fuel v2.1 on the chip itself.

check out the pictures, if anyone has the same unit or can give me some help on how i could go about tunning/adjusting this piggy back that would be amazing!

Also if i am not mistaken this came with the brp cold side supercharger kit back around 2005.

thanks in advance guys!

Check out pics:

 

Pretty sure that's the ELF.
