ECUs - all the same?

[seasider]

Does anyone know if an ECU from a 2005 350z would work fine in a 2004 (54) 350z? There was a model change in 2005 from the previous model with an increase in power etc.

They are different.

 

Also any ECU's from the correct model year would have to be checked for NATS compatibility and programmed to your key etc.

Is it the case then that the ECUs are the same for the 276 model, the 287 are the same, the 306 the same. So as long as it is from a 276 model it would be ok?

No, there are differences + you have the NATS issue.

^ as well as differences from auto to manuals

also different JDM to UK

Also remember that the after replacing the ECU you will have to:

 

(1): Perform initialization of NATS system and registration of all NATS ignition key

IDs.

 

(2): Perform Accelerator Pedal Released Position Learning.

 

(3): Perform Throttle Valve Closed Position Learning.

 

(4): Perform Idle Air Volume Learning:

 

All the above are very straight forward and quite simple to administer.
