Map Availability: Download from the Cobb Tuning Nissan GT-R OTS Map Database

Hardware Requirements: Stage 1 Maps: 1.) Intake: Stock, COBB SF Intake (2.75”), or COBB BigSF Intake (3.00”) 2.) Exhaust: Stock or upgraded cat-back exhaust Stage 2 Maps: 1.) Intake: Stock, COBB SF Intake (2.75”), or COBB BigSF Intake (3.00”) 2.) Exhaust:

Cobb Y-Pipe REQUIRED Stock or upgraded cat-back exhaust

**** WARNING COBB BigSF GT-R intakes must be used with special +BigSF

calibration. Inappropriate calibrations will promote engine damage. Possible lean conditions will damage motors. Those who eventually plan to run fully optimized stock turbochargers, or upgraded turbocharger configurations, will want to use a larger diameter intake such as the COBB BigSF Intake. This intake provides more resolution for the Mass Airflow (MAF) Sensors and will support higher HP than intakes with smaller internal diameter

at the MAF sensor housing.

Some GT-Rs equipped with exhaust modifications produce more airflow than the stock fuel injectors can support. Possible le

an conditions will damage motors. Users must monitor knock and injector duty cycle in when using these calibrations. You,as the end user,must take some responsibility for ensuring the safety of your engine. We recommend larger injectors and fuel pumps tofully exploit the power available in the stock turbochargers. Calibrations for larger injectors can be acquired from one of the many Professional GT-R AccessTUNERs or from one of our COBBTuning Retail Service Centers.

Fuel Requirements:

91 octane or 95 RON 93 octane or 97 RON 100 octane or 102 RON

**** WARNING - Be very careful to use appropriate fuel quality with the map.

Low quality fuels can cause catastrophic engine damage. Use high quality

fuels whenever available.


Typical Power Gains: Stage1 and Stage2 vs. Stock Power

The updated v500 mapping produces a substantive but conservative increase in horsepower and torque. The graph below shows typical torque and horsepower as measured at the wheels on a stock GT-R (blue), COBB Stage1 GT-R (red), and a COBB Stage2 GT-R (green). Stage1 produces a 10-12% increase in wheel torque and horsepower. Stage2 configurations produce 12-15% increase in wheel HP and torque.


Stage1 and Stage2 Boost and Air/Fuel Graphs ◦ This graph illustrates typical boost (PSI, thick lines) and air to fuel ratio (thin lines) for

stock (blue), COBB Stage1 (red) and COBB Stage2 (green). 100 octane and 102 Ron maps produce 1-2 PSI of additional boost. COBB mapping targets conservative fuel mixtures between low to high 11:1 rations depending upon fuel type.

Clo

sing Warning and Precautions:

Boost targets will vary with altitude: Users at higher altitude can expect lower boost. The further away from sea level the lower the ambient pressure. For example, users in Denver CO may see 1.5 to 2 psi lower boost. This is normal and the reduction in boost pressure at high altitude is intended to maintain efficient turbo charger function.

Launch control: Launch control RPM set to 4100 RPM by default (based on region).

Map Version Notes

Non-Performance Maps Anti-Theft Map

◦ Car will not start. Used to prevent theft of vehicle. Economy Map

◦ For Stage 1 and Stage2 cars (see maps below). Sets boost to wastegate setting for better fuel economy. Located in switchable MAP position 1.

Stage0 - Simulated Stock Calibration. For use when stock-like behavior is desired (Stock

fueling and ignition strategy with modified boost control system). DOES NOT UNINSTALL AP FROM THE ECU.

Valet Map - For use with 91 octane or 95 RON or better fuels - low boost and 3500 rev limit

- for Stage 1 or Stage 2 cars.

Revision Notes:

v600 ◦ Updated all non High Performance maps to v600 to support user adjustable LC

v500

◦ Added 2010 JDM Vspec GT-R Support. ◦ JDM: Raised cruise control limiter. ◦ CBA: Enabled Boost Gauge wrap around.


◦ Revised long description in Stage0 maps for clarity.

V361 ◦ BETA HP maps received the following updates:

▪ raised LC limiter to 4100 RPM (unless already set to 4500 RPM for certain region GT-Rs).

V360 ◦ BETA High Performance (HP) maps initially released at v360. BETA HP Big SF intake

maps also released at v360.

v301 & v302 ◦ Real-time map switching with cruise control ◦ Fast map flashing ◦ Heads-Up knock display for CBA GT-Rs ◦ BigSF Intake map support

Feature Descriptions:

1. Real time Map Switching with Cruise Control Buttons. This feature enables users to switch between real-time maps. Once the appropriate v300+ calibration is flashed to the ECU via the Accessport, the end user can use the factory cruise control system to switch between two different maps. The number of available real time maps is adjustable with Accesstuner GT-R software. Custom tuned calibrations can contain up to 9 real-time switchable maps. v300+ maps included with your Accessport or downloaded from the COBB Tuning website contain two maps that are switchable in real-time. Map 0 is the performance map. Map 1 is an economy version of the performance map with very low boost levels (~10 PSI).

2. Fast Map Flashing Fast map flash allows users to switch between maps in 30-40 seconds compared to the full map flash which takes up to 11 minutes (initial install). Fast map flash is dynamically determined by the Accessport during change map operations and is used when applicable.

3. Heads-Up Display Engine Knock Warning Engine knock can be monitored using the factory heads-up-display. Once the knock monitoring system detects knock, the boost gauge will start flashing on the heads up display. This is adjustable through Accesstuner software. These maps provide the ability to monitor knock through the factory display. Once the knock monitoring system detects knock retard above ~2.5 degrees, the boost gauge will start flashing on the display. Indications of knock must not be ignored. Excessive knock will damage the engine.


V500 maps introduced new logic for CBA and DBA ECUs which caused the boost gauge to flash constantly when the ECU enters high detonation mode (which can happen with excessive knock). The flashing rate is faster than the normal knock flash rate and further knock events will not be shown on boost gauge in high det. mode (just a constant fast flash of gauge). When ECU exits high det. mode (requires a key cycle), normal reporting of knock events will resume on gauge (until high det mode is activated again). Note: The high det. mode fast flash is a little too fast for the gauge at times and some may notice a very slight pause in the flashing at times (this is normal). 4. Boost Gauge Wrap-Around Multi. Function Display (M.F.D.) boost gauge now wraps around and displays boost in excess of 20 PSI (~150kPa). Available feature in v500 map calibrations. 5. User Adjustable Launch Control (LC) User adjustable Launch RPM via the Accessport “Tune” menu. Launch RPM can be adjusted in increments of 100 rpm. Available feature in v600 map calibrations.
