Hi I've got a 2006 chrysler 300 with a 6.1. I believe I've got a problem with my ecm failing. It started last year but getting worse now as problems usually do. My question is. Seeing as I can rewrite all of the parameters and maps within the ecm with hp tuners. Do you think it's possible to use a 5.7 ecm, make the changes needed and be off to the races, or do I need the 6.1 ecm? I've compared the files with my 5.7 chrysler 300 and see all of the differences between to two

Thanks for your help
