2015 Mustang ECU SWPN Code
Aquiring the computer code on the 15 Mustang is slightly different than earlier Mustang models. Once you receive your tuner (which will be left blank) use the tuner to read the ECU SWPN. Plug the tuner into your car via the OBDII port and scroll down to vehicle info - the tuner will tell you to turn the key on but do not start the car. It will display a few things including the strategy. Scroll down to ECU SWPN. Please provide Steeda with that alphanumeric code under it.
