Pardon me if this is a stupid question, I've never personally played around with ECM calibrations before. But in the first post you stated that you're current ECM Code is DT904206.06 but the pics you posted show ECM Code DT90426.06? Are these actually the same thing or are they different? If they are different would that affect the analysis Rawze posted? I know it wouldn't change the fact that his CPL calls for a different program, but just wanted to understand the ECM codes.
