Accessport for Porsche 991.2 and 718 Vehicles

The time is finally here!  We are extremely excited to announce the availability of COBB Accessports for Porsche’s 718 Boxster/Cayman and 991.2 Carrera and 911 Turbo!  This project has been in the works for quite some time as these cars share a completely new ECU and required the work of many engineers to dissect and understand.  In the past weeks, we talked a bit about the power gains expected for each car.  If you haven’t seen those yet feel free to take a gander!  The flashing process for the ECUs in the 991.2 and 718 cars requires an extra step before the Accessport is able to communicate.  ECUs will need to be shipped to COBB Tuning to be unlocked, more on that process below.

A New Step: ECU Unlocking

There is a new element to the ECU flashing process for vehicles supported by these three Accessports.  Just as COBB did over 10 years ago with it’s first ECU flashes, we will be bringing ECUs in-house in order to unlock them before an Accessport can be installed.  This means the process for installing an Accessport on your 718 or 991.2 vehicles will be a bit more involved than in years past.  Not to fret, we have a system in place to ensure ECUs are shipped and returned in a timely manner.  Customers will be updated at each step along the way, from the initial purchase to receiving the unlocked ECU and Accessport.

Once an order is placed with COBB Tuning customers can expect to receive two emails: one including notification of the received order along with detailed instructions and a guide of what to expect.  A second email will be sent with tracking information for the ECU return box.  Once that box is received, the ECU can be placed into it with the provided laser-cut foam insert.  A pre-paid return shipping label will be provided for all orders placed and shipped within the United States.

An email will then be sent to the customer letting them know when we receive the ECU and are able to begin the ECU unlocking process.  Once that process is complete, an additional notification will be sent to let the customer know that the ECU and Accessport are packaged up and shipping back to them.

Upon receiving the unlocked ECU and Accessport, customers can now install the Accessport as they normally would.

  1. For a 991.2 with the ECU backdoor added:
    1) Can the Accessport tune be removed prior to a dealer visit?
    2) and can it be reloaded if the dealer updated the ECU with a software update?

    • Hi Rob,

      We are working on an update for additional stage maps that will account for upgraded exhaust components, but as of right now. Our stage1 is the only option but it is meant for stock cats. You can use it in the meantime but there is a chance you will have a CEL. It shouldn’t be too long before the update is ready.

      • Adam, the cats have O2 sensors and don’t throw CELs now.. what would be the difference with the flash?

        • It might not have a CEL with the tune either, we just can’t promise either way since the stage1 tune is intended for stock cats and we don’t disable any codes or anything or force any settings. The tune may produce different exhaust characteristics compared to stock, meaning that the sensors may not be as happy with the tune even if they are fine now. So it’s just purely up to the sensor readings but we don’t test for that since it’s not the correct configuration for the tune. We are working on stage2 tunes right now and it won’t be long before there is an update for them.

  2. When will 2019 support be available? When will Accesstuner Pro be available to your dealer shops?

    Looking forward to getting a protune completed from the boys up in Plano. Let me know anything that can shared. Approximately of course, with no guarantees. Development takes time.

    • Hi Michael,

      It’s tough to say at this point. We’re not even sure whether the 2019 will be the 992 or not yet. Once the new model year is out, we’ll be able to know more. Assuming it is the similar to the 2018 it shouldn’t take too long. If it is the 992, it will be longer.

  3. I am somewhat disappointed with Cobb in the time it is taking to release stage 2 Maps and pro tuning for 991.2 GTS models. I purchased my Cobb with expectations made on this blog and other forums that stage 2 and protune releases “won’t be long” based on comments by Adam back in JULY! That was 6 months ago. The 991.2 has now officially been replaced by a new model. Turbo has pro tuning and stage 2. Whats going on guys?

    • Hey Rick,

      I definitely understand your frustrations with the time to market for Stage 2 and Accesstuner Pro for the 991.2 platform. Unfortunately, the projects have taken a bit longer than we initially anticipated. With that said, I am happy to say we do have a 991.2 GTS in-house for Stage 2 map creation as I type this.
