i have been having ecu problems for a while and i have a question i am currently going to oreder a new ecu but it is from a 04 6mt and i have a 03 6mt, the 04 work for my application?

 

What makes you think you're having ECU problems?

Why would you order an ECU for the wrong year?

 

I've read (either here or on my350z) that ecus, even if they are for the same year and application, have different part numbers that reflect changes/updates made to it.

Only get the same part # ecu that your vehicle currently has, unless there are people who can confirm that different part #s will work with your application.

 

As mentioned on the Orisis topic, you normally have to contact a dealer (should not matter which one) and give them your VIN. They will then be able to tell you which ECU P/N to use for your G (as it came equipped from the factory).
I guess there is a way to get it from the ECU itself by opening it up. Nothing I would mess with unless you are sure it is bad.

 

How do you know the ECU is the problem?
