Bought a ecm for $194 plus shipping. The module did not work. Could not get anybody on the phone to help. All I got was emails sending the same instructions that I already got. So I returned the item for what I thought was a full refund but instead only received $155.20. Called and emailed to ask why and have not heard back from anybody. I would never buy from this company or suggest anybody else to do so. I will also be reporting them to the BBB. Thank you
