Porsche 997.2 Carrera COBB Tuning Accessport V3

Excluding GST |
The Accessport V3 is the world's best selling, most flexible ECU upgrade solution for Porsche. 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. 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.
* With optional COBB PDK Transmission Tuning available for the
3.8L Cars Only
. In releasing a product that has never before been offered, COBB's Porsche Calibration experts created PDK calibrations that we felt would give the greatest performance impact as well as appeal to most enthusiast owners. More information and details below.

COBB PDK Transmission Tuning Optional upgrade for Porsche 997.2 Carrera 3.8L PDK Cars Only
In releasing a product that has never before been offered, our Porsche Calibration experts created PDK calibrations that we felt would give the greatest performance impact as well as appeal to most enthusiast owners.  While the specifics of the map for each vehicle may differ slightly, below is a general representation of what to expect when using one of three provided PDK OTS maps.
All supported vehicles will have the following maps to choose from:
COBB Sport Map
A nice mix between the factory Normal and Sport Drive Modes
COBB Aggressive Map
More ideal for vehicles being used on track or during competition.
COBB High Torque Aggressive Map
not in firmware
Intended for vehicles with significant torque increase over stock.  Requires PDK Relearn after flashing.
Below we highlight features that are integrated into the PDK Off The Shelf Maps.  For a complete list of changes made to the PDK OTS Maps please see the
PDK Map Notes Page
The factory shift schedule is geared towards maximizing fuel economy in Normal mode.  Our calibrators have increased the Minimum Shift Point for each individual gear, giving cars a more sport like feel during normal driving.  The Minimum Shift Points in both Normal and Sport Mode are adjusted and will provide a more consistent and predictable shifting schedule.
With an increased Auto Shift Point cars are able to carry out power a bit higher before initiating a gear change.  This is specifically beneficial to naturally aspirated cars and turbocharged cars with upgraded turbochargers where power is still increasing at the top of the power band.
This feature adds Race Start to both the Normal and Sport drive modes, including cars WITHOUT the factory Sport Chrono option.  The Race Start Lite RPM in Normal and Sport mode will typically be slightly lower than in Sport Plus.
Shift firmness is the culmination of a few variables that determine how quickly the clutches are engaged between gears.  The COBB PDK OTS maps offer slightly increased firmness over stock which translates to a shift more akin to that in a 991 GT3.
Minimizing clutch slip when engaging a gear moves power through the drivetrain more efficiently.   Our calibrators have increased clutch pressure only in the High Torque Aggressive OTS map.  This is intended to be used on vehicles that have a significant increase in torque over stock (50% or more).  As a note, when flashing the High Torque Aggressive map, a PDK Relearn MUST be performed.
Continuous Clutch Slip can often present a sloppy feel when driving PDK equipped cars at low loads.  COBB PDK OTS Maps will mitigate the “gear hunting” feeling by minimizing the amount of slip the clutches exhibit at low RPMs.
