    You can't read the stock file out of the truck? I don't understand, this is very vague can you elaborate a little more?

    correct LML are a Write only ecm unless you pull them apart, EfiLive is write only as well for this ecm, hp supplies you with a base "stock" tune when you attempt to read it
