BMW N55B30 Performance ECU tuning software for BMW F25 X3 35i
Stage 1 gains over stock software:
79WHP @ 6600RPM
83WTQ @ 3900RPM
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. Gains may vary car to car based on conditions and state of the vehicle.
We have 2 methods of having this tune installed (Flash Type Selection).
- BENCH FLASH: Remove the DDE/ECU and mail it in. We will create a full backup image of your ECU without opening the lid or any physical damage to the ECU at all. We then upload our tune and mail the DDE/ECU back. This is the safest way, as we can have a full backup of the entire ECU content.
REMOTE FLASH: No downtime!!! With this option, once an order is placed, we will ship you a cable, that cable connects to a laptop and we are able to remote into your computer to flash the car. The remote flash option includes the cost of the cable (which is yours to keep). In some cases, not all cars can be flashed this way. In that case, you will have to ship your ECU/DDE to us. *You will need a Windows 8 or newer laptop and WIFI to flash remotely (Apple, Chromebooks are not supported)* For F-series vehicles, we use ENET cable for flashing and it will require you to have an Ethernet port on your laptop available for connection to the vehicle.
