    I've changed an ECU to a previous version without any issues.

    Of course, many have done so (including me) when there was a bug in a new EFI software/ECU firmware version.

    Yeah, I was surprised he thought it'd be an issue. Otherwise, they were very helpful. Great community we have here.
