3, This module adds boot mode support for controllers with the tricore processor. Features:

Auto detects ECU and processor type. No need to select from list, everything is automatic!
Read/Write of all memories Eeprom, Irom, Xrom (where possible)
Patch function for OBD Flashing of TPROT ECU's (supports only VAG at the moment)
TPROT / DS check feature, for testing if TPROT is active without opening ECU.
Supports For upto TP12
Supports For Siemens (current only for ECU's without password protection),
Support for unlocking of VAG Simos PCR and For Simos 8.
Checksum Correction supported for  MEDC17.

4, The MPPS is a powerful programming tool. It offers general reading / writing operations and checksum support, however it also includes some additional features:

Excellent recovery functions. In some cases MPPS can recover ECU's which others tools can not even make communications with. On certain controllers it even works when with no program is present (a blank memory).
Selectable full / partial reading and writing when the ECU allows this function.
Selectable reading / writing speed.
Writing "changes only" function for faster programming (when supported by the ECU).
Auto detection of K-Line/CAN, and option to bypass and force preferred means of communication.
Temporary bypass of immobiliser to allow flashing on the bench on ME7 systems.
Boot mode support for ECU's with C167 and ST10 processors.
EEprom read/write functions for some ECU's are included.
For VAG MEDC17 TPROT level checking without opening the ECU.
