DPEdit
A binary editor for 88-91 DPFI Civic/CRX PGMFI systems!
...Originally based on the only option available to modify DPFI tunes from 2007, PsyBIN, DPEdit is heavily modified to the point of being much more complete and period compliant in terms of library dependencies, and functionality!
DPEdit is still in early development and there's much to be desired of the DPFI ECM environment! Do not expect a complete product as development is continued by a very small group of people, me being the main and consistent ONLY. Modifying fuel and ignition timing tables as well as correction tables / scalars can cause extreme engine damage if not done so with extreme caution! Do NOT modify a vehicles tune unless you're 100% aware of what you are doing! ...
