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 3.4L 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.

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.
Cayman R PDK Calibration. This can be used on the 987.2 Cayman S / Boxster S and Boxster Spyder to simulate the OEM Cayman R PDK calibration.
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.
INCREASED MINIMUM SHIFT POINTS
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.
INCREASED AUTO SHIFT POINTS
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.
RACE START LITE
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.
INCREASED SHIFT FIRMNESS
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.
INCREASED CLUTCH PRESSURE
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.
MINIMIZED CONTINUOUS CLUTCH SLIP
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.
Easy to use and loads maps quickly. Came with 93 and 100 octane maps that works well. Datalog feature is really great.
I was working with John on this back in November and successfully tuned my 987.2 (2.9L) MT. Thanks for the all of the assistance and advice! Performance: I haven't Dyno'd the car (before or after) so I don't have any hard numbers to post. The car does seem to rev more freely and pulls harder in the higher RPM. The CEL is gone which makes the tune completely worth it for me! Mods: Carnewal GT exhaust, Fabspeedicon dual tips, cat-less headers and MyGenius Tune, in that order. Notes: Make sure you do not have any CEL or warning lights on. You cannot download your car mapping if any of these show. It takes about 5 minutes to download/upload each map and is super easy to do (I recommend putting your car on a battery tender when doing so). TLDR: This was very easy to do and I recommend it to anyone who has modified their car.
The engine feels more torquey from 2,500 RPM and up which adds to the fun factor of being able to better control the car in corners using the throttle - if one is so inclined. I attribute this to the flattened torque curve which makes the car feel more lively (-;
