Does anyone know of a way to backup, upload, or download software on a 211 Phase 3 with the integrated CPU/IOBD without Otis’ Tool? Like a special tool or comm port settings and commands?

Pull the chips and copy them with an eeprom burner?

There are not removable EEPROMs on the newer 211. The Baseline software and parameters are stored on surface mount FLASH. I have a manual on the procedure with Otis’ “Smart Service Tool” that accepts a memory card. I think now they use a dongle and their phones to manage the software.

To replace the IOBD, I have to get it fully programmed from Otis with the job # so no backups and no spare board on a job with 14 211s.
