Hi There,
    I bought a 2002 Nissan Maxima 3.5L V6 6 speed manual, as a donor for =
a mid-engined track car.  The Maxima was a theft recovery and did not =
have an ECU in it when I received it.  I have purchased a remanufactured =
ECU, but no luck starting it.  There is no spark, though the engine =
turns over freely. =20
    I have found out that the ECU, IMMU and Key are part of a vehicle =
immobilization system called NATS.  Can the ECU be modified to operate =
with the NATS disabled and/or eliminated? =20
    I still have the engine and trans in the car as I want to start it =
there before taking it out to install in the track car chassis.  =
Ideally, I would like to be able to turn the ECU on with a dash mounted =
switch, and a button to engage the starter.  I am about to break down =
and have the car towed to the Nissan dealer to have the key. IMMU and =
ECU initialized, so that I can start the car.  Any insight you can share =
about my plans would be appreciated.    G;-)
