Stage 2 Software Optimization for Alfa Mito QV.       What you need ?:   -Downpipe (min 2,5" size)   -Free flow full exhaust (min 2.5" size)        Suggestions:   - cold air intake   -DV upgrade       Stage 2 calibration for the 1.4 Multiair 170-180 HP engine units (Garrett MGT1446Z Turbo). A completely smooth experience. It has been prepared by testing and logging in all road conditions. Air mass flows have been calibrated. Wastegate PID have been smooty. Torque demands have been optimized. The fuel-air ratio is programmed for maximum power and torque. So a lot of changes. Dynamic mode 1.6 bar peak 1.3 bar rev limit boost. Normal and All Weather 1.4 bar peak 1.1 bar rev limit boost. It also works perfectly with 95 octane fuel, but 98-100 octane is recommended for full power.    This ecu can be written via OBD, but programming in bench mode is safer.  

The vendor has uploaded their files and can be downloaded directly after paying. Even if software and hardware numbers of ECU are the same, it could be it is different because different tuning tools can have a different way of reading/writing cutting parts of the software or adding code. You need to use the tuning modifications and copy them into your own original file or let vendor customize the file for you.
