Hey! Awesome to hear you're up and running!
I'm doing the same swap as you've just finished and have run into the same immobilized issue. The swap shop sent me a V9 ECU L300. They have a AH580, but I need to know if this will work correctly with a tune. I have the tune file to go into it as soon as the right ECU shows up.
What ECU did it for you? 22611......
Thanks for your help!
