You need more then the ECU, you need the full harness (from ECU to engine) and might have to do some wiring to the fuse box plug...

I wouldnt say its worth it because you also need the TB from the "i"...And even then the ports on the head are still small, same with the valves, exhaust manifolds, downpipe, exhaust...Better to do a full "i" head transplant but its a lot more $$$
