COBB Accessport V3 for the BMW N54 twin-turbo engine
The N54 Accessport covers the twin-turbo 3.0-litre six found in the 135i, 335i, 535i and 1M. It reflashes the factory DME over the OBD-II port.
This is the most broadly supported unit we stock. COBB's map notes list ADM, EDM and World Market coverage for the N54, which means Australian-delivered cars are explicitly included rather than covered by inference.
Why the N54 is the popular one to tune
The N54 is a turbocharged engine with a lot of headroom left in the factory calibration. It also responds well to the supporting modifications most owners already have, such as an intercooler and a charge pipe.
What you get
- Off The Shelf maps across the N54 range
- ADM, EDM and World Market support confirmed by COBB
- Live monitoring of up to six parameters
- Data logging for later review
Before you flash
Installing an Accessport over anything other than OEM or COBB software may result in ECU or TCU failure. If the car has been mapped by someone else, tell us first.
Accessport V3: what you get
Throw away your gauges!! The new in-cabin mountable Accessport V3 has a large, full color, higher resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up a race, street or dyno gauge cluster) and mounting options (choose from 1,000s of standard vehicle mounts). Of course, all of the great COBB tuning is included - with enough space for 100 calibrations. This is your new Accessport - and maybe the last one you'll ever need.
Why owners fit an Accessport
The Accessport V3 is the world's best selling, most flexible ECU upgrade solution for BMW. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Upgrade forever with off-the-shelf (OTS) calibrations for most bolt-on modifications. It's the last engine management solution you'll ever need.
