Go to the passenger side floor board, the carpet should pull up at the top right corner. There will be four 10mm bolts, accompanied by a "ecu sheild." Take them off, take the ecu off of the bolts and look for the white sticker and look for the "p" and two numbers will follow it, that is your ecu code.

if its stock

Si ecu-Pm6
HF/DX ecu- Pm5 dual point ecu.

Keep looking at the sticker, it'll have either a PM/PR/ OR a PG, in the middle. and after the first two letter's if its obd0 itll have one number after it. Look in the middle, or just take a pic of it and ill tell you what ecu you have....what motor do you got?

You're looking at the right sticker but the wrong letters.. There will be a string of numbers, and the ECU family code is in the middle of it.

More than likely you have an OBD-0 PR3 ecu.
