It
should just work, yes. As far as hardware goes, I don't believe the ECU changed significantly through the VIII models; even the IX ECU isn't all that different, as it's basically the same processor with additional ROM (512KB vs. 256KB) and RAM (32KB vs. 12KB).
Honestly, I'm a bit confused myself. rdtech, I just noticed that you mentioned that you're able to run on the old ECU. So, I'm curious what's prompting you to swap to a different physical ECU?
