5-speed swap done! Now to just tune the ECU. I'm probably going to get an S70 T5 ECU that already has MoTronic 4.4 on it, and turn it into a T5M ECU, via open source programming. M tune will hold RPM's while I shift. Even today, I drove about 100 miles with the manual, still easy and smooth to drive when double clutching.
