Hello I own a 2002 Mazda Protege 5 ES. I understand that the Mazda MP3 has 10 more horsepower than the regular 2.0 liter. I have spoken to the dealer to find out how this was done and they said with a different PCM. The cost of the MP3 PCM for the standard 5 speed is around 1500 bucks up here. I have this site that allows you to download and reflash your PCM to the latest available firmware I guess. If I was able to to find out what one is for the Mazda MP3 with a 5 speed stick, could I just flash it with the MP3 file and have it change mine instead of replacing the existing PCM?
