Default 04 wrx w/ 02/03 ap?

So I bought an 04 wrx just over a month ago. I recently got the AP from the previous owner. Upon starting it, I saw a bugeye. I then looked at the maps and saw it read "stg 2 wrx 03" which I thought was strange. I then looked and the AP is for an 02/03. Is there anyway this AP could be working on my car?

This car was sold to me with the previous owner saying it was a reconstructed title due to theft recovery, which I believed as the front seats were 02/03 and so was the gauge cluster. Carfax didn't show an odometer disclosure so I figured it had been reset to what it was. Now I'm starting to think maybe the engine was stolen as well and it has an 03 engine in it. Any numbers on the block or computer I can look up to find this?

Upon reading around, I have a v2 AP, so hopefully it just has maps from an 03 in it.

The AccessPORT only cares what model year your ECU is. So if you go to AccessPORT, then About, then Vehicle, it will show you what kind of ECU/car your AccessPORT thinks it is connected to. The AP will only let you install maps for your specific vehicle type, so it sounds like you most likely have an 03 WRX ECU.

Thanks! The AP shows "02/03" in the about, and I just ran 2 different tunes, one looking like a Cobb ots stg 2 91 lc tune, the other being a stg 2 03 dyno tune. There is an economy tune for an 04 on the AP, but it is locked.

Anyone have ideas or numbers off the ecu I can run?

What kind of information are you trying to get from the ECU?

I'm looking for numbers to help me figure out if it is in fact an 03 ecu. Next step is to see if my engine/trans are from an 03...

If the AccessPORT says 02/03, then it is definitely an 02/03 ECU.

Will an 03 ecu run an 04 engine?

An 03 ECU could run an 04 WRX engine, but there might be some variables that could make the car potentially run oddly.

Gotcha. Well I am going to pull numbers off the ecu and the block tonight and see if I can get some answers. Thanks!

Got some numbers. Gonna post this somewhere with a little more exposure.

Block - B515226
ECU - 22611AF423
112000 - 7065
12v
207065K

If anyone can run the block and ecu numbers and tell me what they came out of, that'd be great!
