Hello,
I recently bought your MPVI2 tuner and licensed the ECM of my 2019 Mustang (4 credits) to activate my active exhaust retrofit (used oem parts). Although I see the active exhaust menu on my dash (using firscan as described in forums), and enabled idle switch, load switch and manual control using Hptuners, it is still not active. Is there anything else should I modify? Is is the right programming procedure?I have read on forums that people managed to activate it using HpTuners (Palm Beach Dyno did it for instance)Thanks for your help.
