I know there's a thread with a few gurus here on tuning ecms, way over my head and I hope I don't have to get into that. Does anyone know what years/models are swappable? Specifically, will a 2005 450fse ECM work in a 2007 450fsr? All the numbers on the labels match, but the fiche part numbers are different. MFS450380001 (2005) vs MFS450680001 (2007).
