About TheYellow

TheYellow is the ECULogicX portal for Caterpillar equipment. It covers ADEM A4 and A5 engine ECMs as well as the C-Series (C4.4, C7.1, C9.3, C13, C15) controllers found in 320–352 excavators, 950–982 wheel loaders, D6–D9 dozers and Cat gensets. Site deadlines don't wait, so most standard files are returned within the hour during support windows.
