[Nissan NATSII and your NS15G4]

I am just doing research at the moment and it's for a cost saving exercise more than anything else. I've not bought the ECU yet. Considering NATSII is a Thatcham Category 1 recognised immobiliser and it's already there as standard on UK late model 200SX's, I thought it would be good to keep if the hardware could work with the G4. Maybe the information I am asking for is a bit security sensitive, so I understand if people don't want to give it out.

Do you know this specifically, though? Do you know in what way NATSII is linked in to the ECU? I know the the ECU is disabled if it doesn't get the signal from the halo on the ignition barrel, but what more to it is there?

Hello, If it is known, could you tell me if your NS15G4 plug-in ecu will be compatible with Nissans own NATSII alarm and immobiliser system? I'm looking at standalone management options, but I will also need Thatcham Cat 1 alarm and immobiliser for insurance purposes and I'd rather not have to fork out for more equipment than I have to when NATSII is perfectly good. Thanks, Tom.
