PPD Maps is open source (GPLv3) software for detecting maps in Siemens ECU dumps. Supported ECUs are PPD, SID206 & SID803A. There is partial support for SID803 and barely working support for SID201
The software will identify the corresponding axes for each map and also give a list of DTC/P-codes. It will also find single byte switches to turn off DTCs
The file must be a full read of the ECU i.e. BDM. A partial read using a tool such as MPPS or similar will not work.
