OK fast info on car. It is a drift ****, I have a custom chassis harness I want to install but to do so I want to remove this damn thing. Is there a way I can wire the ECU so I can take it out???

 

The key, BCM and the ECU all work together to keep the NATS active. I think the only way to disable it is by loading a map from Uprev, specified to disable the security.

(@Uprev / Z experts: correct me if I'm wrong)

 

And I totally put this in the wrong section. Too tired I guess. lol It should be in the 350z section. well does anyone have link to ECU pinout. Normally there should be a hot wire that when the immobilizer gets the proper key installed it send power to the ecu so it will turn on. Well at least the older systems I have worked on where like that.

 

You need an Uprev reflash to disable NATS. That is the only way. PM me if you've got any questions about how it works

 

^there's your man right there.

 

Damn, I have utec... The motor is going into a S13 after round 2 of the drift series so wanted it to be easier when i did that too.

 

Sell the Utec and go with Uprev. Lots of local guys here doing VQ swaps and they're all Uprev tuned.
