AA is NOT working on one either so who ever told you that rumor is way off base.

It's a bit different modifying an ECU already programmed for FI versus one that was not programmed for FI. Also, tuners are doing great things with BMW FI cars, but they are essentially working without the documentation that engineers at BMW readily have access to. So imagine trying to add FI to the N52. An engine that has Mi/Ag and Valvetronic.
Initially, BMW even forgo'ed the valvetronic technology in the N54 engine due to being unable to working out the issues adding it alongside valvetronic. It wasn't until the N55 was released with it. So once again... imagine how difficult it would be for a tuner to solve an issue that even BMW had trouble with.
Lastly, although they haven't 'officially' announced it, AA is most likely working on a SC for N52, a certain AA employee is eluding to it in other threads. The difficulty factor is 10/10 so they most likely won't say anything unless they are successful with it. If they are successful with the N52, it will increase their reputation beyond what it is now.
