Just wanted to share 1 of my builds, its running a maxx ecu on port injection only, DI holes are plugged, maxx ecu controls every factory component like water pump, vanos,throttle body,e9x canbus, fuel pumps, and anything else you can think of or want, this car is more track oriented as its going for the 1/4 record held by ghasssan. Has 8.8 diff, dss axles, stock 6 speed manual, with x clutch twin disk.also features a 1200hp w2a intercooler that does extremely well. All fab work and wiring done by me, also not alone on this project as @willettrun had a big help with all my questions on wiring and he did all the configuration and setup on the maxx ecu along with the tuning. Car starts up , drives normal like any other 335i even with 2200cc injectors on e85. But the big difference is having full control of everything you want. Antilag, launch control, 1 post 02 sensor, boost by speed,rolling antilag the list goes on, this beats paying the crazy money for a syvecs unit and having all the same features for a fraction of the cost. This is the first n54 in the states running this, also is the test car. As we plan on making plug and play harnesses available.
