" I can't remember screen name, but if you search around there is a guy who swapped in an N54, welll 335 interior as well though in an older BMW chassis, can't remember which to be honest. Like I said though, MOTEC is an option. Definitely not going to find an inexpensive option on this motor, so be ready to spend some coin. I really am not sure how a standalone would fair controlling VANOS, DI, anti-knock sensors, etc. I think you'd lose a lot of what enables the N54 to do what it does.
Seeing someone do a PI swap on an N54 into another chassis though would be something. Especially a very lightweight chassis since the N54 is after all, on the light side. I think for what you're looking for that would make for a great project. I can tell you right now NO ONE has done any standalone on the N54. There is one person I can think of that was using a MOTEC system to control another set of injectors for supplemental fueling, this was someone Terry@BMS mentioned at a 1/2 mile event last year. Haven't heard anything since though.
Good luck with the project! "
