So i realized that the shark injector chip that i used for my 2002 330xi can be used wit my gf's 2001 530i.

My 330xi was on lease, so therefore after the lease was over i simply UN-installed the chip from my 330.

Does the shark remember what car you previously installed a chip on even if you UN-installed it, BECAUSE if it does not, cant i use it for her 530?

Thank you.
