2005 or 2007 ECU?

[Larryfishes53]

My 05 Mustang Gt auto tranny is toast, motor has 147k. Bought a 2007 4.6 and auto trans with 77K. Motor has Detroit Rocker cams, CAI with tune and long tube headers. Can I use the 07 ECU? Or do I need to stick with the 05 and by another SCT tuner and install a new tune ?

I would use the 05 ECU that matches the chassis and tune it for the mods in the new motor.

I thought I remember back in the day when I was ordering a tuner that in '07 they changed up the language or something for the ECU. If I remember correctly there were two different part numbers for the tuners. One for 05-06 and one for 07 up. I'm not real positive on this as this was 15 years ago and my old fart brain gets a little foggy.
