Hello everyone. I am from Bucharest and I am working on a 2004 Suzuki Jimny 1.5 DDiS, 65 PS, with the Delphi DDCR ECU.

My main interest is understanding the original calibration before changing anything. I have an FGTech 40 KB read and I am comparing it with matching Renault 1.5 dCi files, using WinOLS and Ghidra for the C167 code where a complete binary is available.

At the moment I am concentrating on map addresses, axes and checksum behaviour. I prefer to verify a definition against code or several matching files instead of naming maps only from their shape. I hope I can contribute some useful DDCR findings here and learn from members who have worked with this older ECU.
