COBB ACCESSPORT ECU FLASH UNIT (OPTIONAL TCM SUPPORT)
Cobb AccessPORT ECU Flash Unit (Optional TCM Support)
The AccessPORT is the most user friendly reprogramming device for your vehicle's computer...not to mention it's stage 2 setting gives your GT-R an extra 70+ all wheel horsepower and 90+ all wheel torque at certain RPM points when coupled with a Y-pipe and exhaust! This is by far the best bang for the buck modification for your GT-R. When coupled with a Y-pipe and catback, your GT-R should see mid/high 400 AWHP. The provided mapping will optimize the air/fuel ratio and ignition timing, remove the speed limiter, and more tweaks for performance results you can instantly feel!
But the AccessPORT is so much MORE than just a REFLASH DEVICE. It allows you to also read any of the DTC (trouble) codes on the various computers on the GT-R as well as clear them out of memory (reset them).
The AccessPORT provides complete control over the factory engine management system. Using the provided Stage 1 or Stage 2 calibration maps in conjunction with appropriate exhaust modifications, users can see significant performance gains across the entire power band. The AccessPORT also provides users with many convenience features such as anti-theft mode, economy mode, and valet mode calibrations along with a fully featured DTC code reader. More than just a programmer, the AccessPORT is the ultimate all-in-one solution for the GT-R enthusiast.

AccessPORT features:
* Reflashes ECU through factory Data Port (OBD2)
* Ability to uninstall and revert back to original (stock) ECU data
* Ability to store multiple maps, allows switching between maps at user's convenience
* Ability to read DTCs (trouble codes) from the ECU, BCM, Multi-AV, IPDM, Pre-crash Seat Belt, Meter/M&A, and Adaptive HL computers
* Ability to clear DTCs (trouble codes) from all vehicle computers including 'Bonnet Light'
* Ability to update reflash maps as improvements become available
* Periodic Internet updates providing new features and improved support
***For an additional 500$, the unit includes transmission control module (TCM) support, thus creating the world's first hand-held ECU and TCM flashing, managing and monitoring assistant, adding a whole new level of transmission control on top of the already impressive engine management capabilities of the original GT-R AccessPORT. GT-R owners can install maps to enhance launch control and make changes to important transmission settings that enhance drivability and improve performance, all with the simple push of a button!
Just like the original AccessPORT for the Nissan R-35 GT-R, installation is simple. No tools are required. No additional “piggy-back” hardware. No mailing the factory ECU or TCM across the country. No vehicle downtime. No waiting. Not even a computer is required. Just plug the AccessPORT in, flash the ECU and TCM, and enjoy the thrill of increased torque, horsepower and transmission responsiveness.
Installing the AccessPORT on the TCM starts with downloading the OEM TCM ROM for safekeeping, so the TCM can be returned to its stock configuration at any time. Once the OEM TCM ROM is stored, the AccessPORT flashes a new Level 1 map onto the TCM that is based on the Nissan LC2 logic upgrade, but increases launch revs to 3,300RPM and includes more aggressive clutch engagement and throttle curves than stock LC2 logic. The result is a positive launch that gets the GT-R off and running harder than the stock LC2 logic, but with smoother clutch engagement than the previous LC1 logic. Still not enough for you? A simple reflash of the TCM with the Level 2 map will have you experiencing the increased punch from raising the launch revs to 3,750RPM!
The R-35 GT-R transmission is an impressive, but complicated engineering wonder, and sometimes adjustments are in order to get it just right. Excessive clutch drag while stationary will cause the GT-R to want to creep forward at a stoplight, while too little drag will make it feel like an automatic's torque converter. COBB Tuning has implemented Clutch Touch Point adjustment via the AccessPORT, offering +/-7 levels of adjustment to set clutch drag right where the driver wants it. This is a live adjustment that does not require a TCM reflash, simply select the desired level of the Clutch Touch Point engagement, hit Enter and drive!
The original AccessPORT opens the door to impressive power gains for the GT-R, which can exceed the transmission's ability to manage that added power, resulting in clutch slip and excessive clutch wear. The AccessPORT with TCM support offers Clutch Capacity adjustment, which controls the hydraulic pressure applied to the clutch plates. Yet another on the fly adjustment without the need for a reflash, simply select Clutch Capacity from the AccessPORT menu to reveal +/-7 levels of adjustment to control clutch clamping force. Higher horsepower GT-R's can eliminate unwanted clutch slip with a +2 or +3 level of Clutch Capacity. Don't let all that power go to waste!
Due to the complex nature of the GT-R's transmission, normal wear and tear can cause jerky shifting and less than ideal drivability. Nissan recommends an annual gearbox optimization routine to recalibrate the transmission. The AccessPORT with TCM support incorporates this Clutch Gear Learning routine and allows the owner to recalibrate at will, without a potentially expensive trip to the dealership. Simply follow the step-by-step instructions via the AccessPORT screen and recalibrate the transmission to eliminate wear related drivability compromises.
Of course, the Nissan GT-R AccessPORT with TCM support comes with all of the power gains and features of the original GT-R Access- PORT. Store multiple maps, live map switching on-the-fly, fast map flashing, factory in-dash display knock indicator, data logger, monitor engine sensors, measure 1/4 mile and 0-60mph times, read and clear DTC codes, even flash a valet map to prevent abuse while out on the town or an antitheft map to prevent engine start. For the ultimate power gains, have your GT-R professionally tuned on a dyno by a tuning expert and extract the maximum horsepower available from your combination of performance enhancing modifications. And should the need ever arise, simply uninstall the AccessPORT and the ECU and TCM are restored to their original condition.
The COBB AccessPORT with TCM support is the ultimate engine and transmission management solution available for the Nissan R-35 GT-R. Access the potential!***
* Please note that TCM support is designed for stock GT-R transmissions. It is not recommended for GT-R's with aftermarket clutch packs and other non-OEM components.*
