I contacted lambda tuning and they told me that they have tuned many 02 Impreza rs2.5 ecu’s with their tuner. I’m currently going to save up to buy the Bluetooth tuner and the tuning license. I think the total including a custom map will be roughly 600-700 bucks. I’ll get back to you guys after I buy them and install the tune.I have an 02 Impreza (NA ecu like yours). Check out project lambda tuning, it allows you to reflash your stock ecu. You can play with all the maps yourself or have Mike tune it for you. He did a great job with my swap and is a great guy, he’s really easy to work with.

What I wold like to know is is it the cable or the software that makes the ECU fro 02 2.5rs not tuneable unless you pay $500
I did a JDM swap with that EJ 208 out of a 2006 Subaru Impreza TwinTurbo from Japan I plan on adding turbos to the carEventually but between now and then I would like to be able to tune the EC you so I could put bigger fuel injectors in it and other such things.It's gonna be the software. You can buy a Tactrix cable that interfaces with any 1996+ Subaru (or any 1996+ car for that matter), but without software it doesn't tune anything.
From my experience with having my car's tuned, $500 is on the high side for getting a "road tuned" and on the low side for a dyno session. I think you've discovered why tuning for N/A subarus didn't really go anywhere - most people can't stomach paying $400-$500+ for a 10-15hp gain.
Yeah man this was super easy way of flashing the ecu and Michael has been super helpful he can help you if you have any problems. I would recommend making sure your car is 100% with maintenance and such since I have to now fix a few things before I continue sending him logs.That's awesome! I know this thread will be useful for future owners of NA Imprezas as well.
