Though it won't run correctlty, it should still start......I'd say just go borrow someone elses ECU for a minute to test out whether it works, and then trouble shoot it from there. There really isn't any easy way to remove an immobilizer, but you can have it done. That being said, to chip and OBD2 ECU it'll cost you a fortune, as to the best of my knowledge the only place that does it, is a company in Japan called Mines.

Good luck,
