I’ve got a PS3 diesel that I tried to add to the list. It will not even recognize it at all. This is a first for me. I have had in the past, got the message not found. When I hit the add MTH engine, I get nothing. I rechecked to make sure the switches were in the right position and still nothing but a blank screen on my tablet. I did put another unit on the rails to check to make sure the system was working, and everything checked out fine. Starting to get a bad feeling about this engine that won’t add.
