You should run an ECU that's compatible with the engine. If it's a USDM WRX motor, then a USDM ECU.

In the end though, you really ought to be talking to your tuner for what to use.

Speaking in USDM terms...

You're running a '02 EJ20 with a stock TD04? You can run an 02 ECU and flash any suitable map for your accompanying mods. You can also run an 03 or 04 ECU, but you'll throw a meaningless CEL which you can turn off when you reflash. I don't think an '05 works for some random reason, but it's been about a decade since I looked into it.

if it is running on a GF8 ECU, I am guessing you will need to sort out wiring to use the GD ECU....

What the heck is wrong with our mods?

Move this to the EJ20 section, or to the swap section.

The newb section? This is not an appropriate question for this forum, clearly.

Jesus guys, is it that hard?

It is. I was going to and then got busy at work. Now I'm back and will move it.
