yeah im using a pcf-901 jdm obd2 ecm which is almost exact drop in for a 2001 obd2 usa ecm with no immobilizer but my car is an automatic so its a perfect fit. Ran it a little more today just idling and a few revs still no check engine light which makes me so happy!
I cannot express how jealous i am of you right now for this. Grrr
