Please note that for Ford, the following is true: - Starter binaries are supplied with the XDF TunerPro definitions, and it is advisable to use these. - Any EEC-IV binary you use must begin with code (FF FA etc). So, it must be a 56k or smaller file. - If an EEC-IV has 2000 hex of blank padding at the front that will NOT work! - These files should allow emulation and binary editing. - For EEC-V, you MUST use a 256k file. This is a full 4-banks of information, arranged as 64k blocks from banks 0,1,8,9. - If you do NOT have padding in your EEC-V file, or if it is arranged differently, this will NOT work! - This means no 112k, 128k, or 224k files. Also nothing that is like a 2-bank Bank8:Bank1 combo. - Only 256k 0189 EEC-V files should be used, such as what comes out of a BURN1/F2A/F2E combo.
