I purchased an ecm for a 2005 mercury mariner on november 4th 2018, and it would not communicate with any snap on engine scanners or with any program process from a lock smith. After I took it upon myself to send this back 3 weeks ago it did get a response email that said that they have received my ecm and after they test and check it out they will get ahold of me within 4-6 business days. I lost a great customer and $1300 over this ecm and this company so I am writing this and hoping I can save anyone else from losing as much as I have with this company. I know that I will never see any return or will not hear back from them over this issue, I just wish I knew that they had a piss poor reputation before I purchased from them
