Also, i see we forgot to mention the issue these engines have with the valve guides breaking off and clattering around on a valve at rpm this will cause knock readings. a mild annoying ticking noise is usually present as well. this is something i have seen commonly and when the broken guide tip finally breaks off the valve say goodbye to a piston and head. i am sending another revised file for you. just try it out and go from there. remember to clear codes after flashing as it will sometimes put trans in 3rd gear limp mode. Cheers
