Once you toss an ECU and external IC into the mix, you need valvetrain and proper fuel supply to get your ratio right...Invest in a A/F reader to make life a little easier, as each build is different...
On a side note, if you can swap the Rotax IC for something else, you'll get better airflow...The Rotax is a good unit, but restrictive compared to others...
