What’s the difference between pcmtuner, fetrotech tool and MPM ecu tuning tool?

What’s the difference between pcmtuner, fetrotech tool and MPM ecu tuning tool?   

Here’s the clue.

PCMTuner App

PCMTuner App is an application that can control pcmtuner flash, fetrotech, MPM and more feature plugins from pcmtuner team.  The appliation provides instructions and wiring diagrams.



PCMtuner is a customized read-write device specially used for vehicle engine control system (ECU) and transmission control system (TCU).

PCMTuner flash is based on pcm-flash which comes with 67 modules. The smart USB dongle stores the protocols. The dongle can be purchased alone (to work with ktmbench, openport, SM2 Pro).

PCMTuner vs PCMTuner dongle

Pcmtuner is a complete hardware device with future expandability linked to the pcmtuner software suite. The dongle allows you to run the pcm flash modules etc

PCMtuner flash can read and write ECU via OBD, Bench, Boot, OBDvr modes.


Fetrotech Tool:

Fetrotech Tool

This is an add-on device that uses its own software for bench work on ecus. It is for bench work only on the ecus it supports.

Fetrotech will connect with the pcmtuner to get more protocols and it can be controlled by pcmtuner app to access pcmtuner account.

Fetrotech does what pcmtuner doesn’t do, the MD1, MG1, ME9, EDC16 (not all of course).

The black box tool has pcmtuner port, it can be used standalone or use with pcmtuner. The silver one must be used with pcmtuner.


Mpm Ecu Tool

MPM is an entirely different device. It is an ECU-TCU integrated module used for the reflashing and debugging of American cars, it supports general motors: Cadillac, Chevrolet, Buick, Ford, Dodge and other American models, with some opel and saab covered too.

It also can be used to record the engine data log for Japanese and German models and extract the data stream, so that the tuners can better get the engine and gearbox data too achieve better tuning.
Comes with its own Software suite VCM Editor for calibration, map editing, logging and more!
