Hey guys, put together what I believe to be the first Rest Of World flash with PIWIS on video to show you how it's done. Pulled together what little info I could find sprinkled around around made this guide to show you exactly what to do! Hope it helps, would have helped me if someone else had done this
(FYI my reason for doing this was because I deleted the SAI - Secondary Air Injections system)
