BMW N55B30 Performance ECU tuning software.
We offer this tuning via OBD2 flash option at this time, we will mail out a cable that you will keep. If OBD2 option is not possible, then we can flash this ecu here on the bench.
2 Stages of Tuning available for the N55B30 F-Chassis Vehicles:
Stage 1 tuning is for all stock hardware.
Stage 2 tuning requires bolt-ons to be able push more power safely.
Performance tuning modifies torque limiter maps, boost levels, fuel maps, ignition timing advance maps and more. All to help safely increase HP/TQ, while keeping good drive-ability and factory fail-safes/limp protection in place.
Dyno graph is a before and after of a stage 2 tune.
