ECU reflash / Engine management system

Hello all,

I don't have a Veloster but the car look is WOW.

I have a mazdaspeed 3 2008 stg3 (357WHP with GT2871R turbo) and I begin my search to replace the car in 2013.

I try to found somes info on ECU reflash system like Cobbtuning or any software like Versatuner to do the re-calibration of the VT ECU database.

(Sorry if somes grammatical mistake the french is my first language)

If you have somes information on software or reflash tool please post

Thanks a lot
