RISEUPF30 · 02-22-2016, 07:15 PM

Just looking for some information, done some research and all signs point directly to n54 not n55. anyone tried this? My mods are muffler delete and BMS intake. dont plan on doing downpipes, charge pipe, etc. thanks everyone

n54tech forums (BMS) shows there is no Backend Flash for N55 yet at least not on the F-series..
MHD is popular on the E90 (n54) for sure

A charge pipe is probably a good idea, piece of mind if nothing else.

There is no back end flash as the ECU encryption has not and most likely will not be broken. Only flash that is available is a bench flash where the ECU is drilled so encryption can be by-passed.

Fingers crossed something comes but its been several years with no success..
