Hey thanks man! Yea we pulled a donor ECU from a wrecked SI and it was confirmed to have the same transmission. What we are doing now is to drop the SI programming in where the I programming used to be this way all of our other programming remains the same except for the engine tune. Their are a few road blocks that BMW threw in their that gave us a curve ball but we are working around that stuff so pretty excited. I hope It will offer a great and cost effective mod for the z4 "I N52" community to get the most from their cars without going the SC route.
