Be aware that sometimes on the non-immo ECUS they swap a couple of pins to stop you using a non-immo ECU instead of an immo ECU. That shouldn't affect you but you should check the resistors on the circuit board to ensure that there isn't a jumper that sets the ECU as immo/non-immo. Please let me know if you get this working.
