Is it possible to swap in an ECU from the MP3 into my 2.0 liter Protegé (5)?
It is possible to swap the ECU from the MP3 to the normal 2.0 liter Protegé. It has been generally agreed that swapping the ECU is not economically sound because of it’s meager 10 hp increase. It will definitely be difficult to find one of these ECUs at a junk yard. However, if you feel making your Protegé into an MP3 replica is your mission, you can always get the ECU from the dealer. As with all new factory ECUs, they are very expensive. The MP3 ECU will run you close to $1000 from the dealer. If $1000 is chunk change to you, here is the part number: FS9N-18-881C. If there is an MP3 owner (who just installed an aftermarket turbo kit) who wants to make an ECU trade with you, that will work too. One thing to keep in mind is, while the MP3 ECU will work fine on the normal Protegé, the normal Protegé’s ECU on the MP3 will trigger the “check engine” light due to less emission control components (thus “malfunctioning” to the ECU).
