I was wondering if an 04 ECU work on a 05 car besides, the getting the immobilizer fixed? I want to flash an extra ECU for my car and leave the 05 stock. So can bring my car to the dealer for some BS moldings to be done. TIA

 

the rom for both years is quite different, u d have to ask the tuners here if it s possible ( dynoflash, works, vishnu)

 

My brother works for mitsu.....he says they will not work. Also dont forget your key has to match your ECU or it wont start.

 

The 03 and 04 are interchangeable if you have the key code and imobilizer code programed

The 05 is different

 

Thanks guys
