ok we had the same problem with our lancer/ you will need that oem # to match (the one that starts with MR) . I found an ecu new on ebay for about 94.00 beats 1200.00 quoted brand new at an auto parts store. or go online to find a junk yard with one....may still be about 100.00 to 200.00 hope that helps
