The MPPS V21 is a bench-tuning interface for reading and writing engine ECU maps over OBD and on the bench. This version adds a reset button that removes the old 10-use lockout, plus a Tricore module and multi-boot breakout cable for Tricore ECUs. It covers Marelli M3.8, M5.9, ME7xx, MED9 and MED17, Bosch EDC15, EDC16 and EDC17, and Delphi, Siemens, Delco, Sagem and Trionic units. It suits DIY tuners and small workshops working on older diesel and petrol cars; it is a clone-grade tool, so expect manual driver setup and no firmware updates.

Owners of this tool generally report it reads and writes the ECUs it lists, and the reset button is the main draw over the older locked version. Complaints center on setup: driver and antivirus problems, and devices bricked by firmware updates.
The MPPS V21 is an ECU chip tuning tool. This version includes a Reset Button, a Main unit, a Tricore module and Multi-Boot with a breakout Tricore cable. It works with MPPS V18 and MPPS V22 main ECU tuning setups.
The older MPPS V21 locked after 10 uses and needed a factory reset. This version has no usage limit, because the Lifetime Use Reset Button allows continuous operation without a lockout. It also adds support for advanced functions on Marelli ECUs.
Do not update the firmware. An update locks the device, and a locked unit must be returned to the factory for reprogramming. Disable antivirus software before use. Install the drivers from the included CD before opening the software. Drivers from other MPPS versions may stop the software from opening.
