I can't find RomRaider ROM and logger definitions for my USDM 2000 OBW 2.5l H4 (EJ251). There aren't any on the RomRaider website, AFAIK. I thought I have seen people here use RomRaider with their MY'00 OBWs, but I might be wrong.
Go to the ECU definition and Logger definition links I included above. Scroll down to the end of the first post in each. At the bottom of each (first) post there's an attachment -- a file in .zip format. Download the attachment, unzip the file, and follow the instructions for saving linking the files.
My ECU isn't listed either, but Romraider logger works fine; all of the available parameters (PIDs) according to the factory service manual are displayed. ECU definitions for a specific ECU/ROM are apparently needed only if Romraider is to be used to edit the ROM, or to access the Learning Table Values.
