COBB Accessport V3 for the Nissan R35 GT-R
The AP3-NIS-005 is the COBB Accessport V3 for the R35 Nissan GT-R. It plugs into the OBD-II port and reflashes the factory ECU, so you get sharper throttle response and more usable mid-range without pulling the ECU out of the car.
It doubles as a gauge package. The handheld shows up to six parameters at once, and you can set the layout up as a race, street or dyno cluster.
What it changes on a GT-R
The Accessport replaces the factory's conservative calibration with a more aggressive one. COBB ships Off The Shelf maps for the R35, and you can move to a custom map once you start changing hardware.
Before you flash
Installing this Accessport over anything other than OEM or COBB software may result in ECU or TCU failure. If you are unsure what software your car is running, contact us first and we will check.
Fitment and market spec
Confirm your model year before ordering. COBB builds market-specific hardware and calibrations, so a unit built for another market is not the same product as an Australian one.
Accessport V3: what you get
Warning! Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. Please contact COBB Support if you have any questions.
Why owners fit an Accessport
The Accessport is the world's best selling, most flexible, and easiest to use ECU upgrade solution for your GT-R. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Follow our staged upgrade path with pre-loaded Off The Shelf (OTS) maps or use custom mapping for any modification level. It's the last engine management solution you'll ever need.

NISSAN SPECIFIC FEATURES:
COBB Adjustable Traction Control: Adjust target traction slip on the fly (Slots 1-8) and maximize tire grip to best suit given track conditions (wet/damp/dry/street/slip/burnout/etc). Note: Feature must be enabled in ECU calibration for use.
COBB Adjustable Launch Control: Adjust the factory launch control RPM to maximize the tire to pavement contact for that perfect launch. Note: Feature is only available on AP3-NIS-006 and AP3-NIS-008
COBB Boost Gauge wrap around: Monitor boost past 20 PSI (~150 kPa), which is an OEM limitation on the factory Multi-Function Display. The boost gauge will wrap around and display excess boost pressure.
COBB Boost Off The Line: Dial in boost to optimize launches beyond the factory Launch Control logic. Boost Off The Line builds boost to spool the turbos for that perfect launch. Note: Feature must be enabled in ECU calibration for use.
COBB Knock Indicator: View knock events, as they occur, on the factory in-dash display. Learn More.
COBB On The Fly Map Switching: Switch to another map on-the-fly while you drive for optimal tuning for every situation. Learn More.
COBB Realtime Tuning: Changes can be made to the map in realtime, while the engine is running. Greatly speeds up the tuning process and allows quick changes to powerful features like Launch Control, Flat Foot Shift, and map switching.
COBB Rolling Boost: Load up the turbos to create boost for roll race events. Simply hold the cruise control button, “Set Coast” to build boost. Note: Feature must be enabled in ECU calibration for use.
COBB Speed Density Tuning: Tune using the MAP sensor instead of the MAF sensor for big-power builds that exceed the stock MAF sensor's maximum capacity.
COBB Fast ECU Flashing: Allows ECU map change flashing time to be reduced to 40 seconds or less! Learn More.
TCM Flashing: Reflash the Transmission Control Module to enhance launch control, perform factory gear learning, and adjust clutch capacity and touch points. Note: Feature is only available on AP3-NIS-006 and AP3-NIS-008
TCM Logging: Log transmission data monitors to diagnose mechanical issues or improve transmission characteristics. Transmission monitors can be logged simultaneously along with Engine monitors. Note: Feature is only available on AP3-NIS-006 and AP3-NIS-008
TPMS Learning: Easily re-program TPMS sensors for new wheels and tires using the Accessport and prevent cumbersome trips to the dealership!* (*requires common Tire Pressure Positioning Sensor Tool).
