This is just a GUI tool I have create that is based on the ME7 Tuner Wizard spreadsheet. the formulas are mostly the same with some minor changes after puting them against the S4Wiki and cross checking everything. It is based on python and completely open source so anyone can go ahead and play with it.

This is mostly a helper not an auto tune, one click tune software. These are some of the maps that need to be changed and enough basis for a stage 1. Every car, every setup needs to be handled differently.

Future updates and work to be done: 1) Injector Calibration 2)LC+NLS option 3)Common DTC removal (like P0420 for catless)

Appreciate any feedback. If you find any bug or something in the logic that doesn't add up, please let me know. We can all work together to actually make it a solid software.
