The COBB Accessport and Accesstuner Pro software are now compatible with the 2018 Volkswagen GTI.  Owners can now enjoy all of the parts and features they’ve come to expect from COBB Tuning including the Accessport, Stage Power Packages including several MK7 GTI parts, and Off The Shelf Maps.

ACCESSPORT FIRMWARE UPDATES

All VLK-002 Accessports with firmware version  1.7.3.0-16029 or newer are now compatible with the 2018 Volkswagen GTI.  Customers who already have an Accessport can utilize Accessport Manager to update their firmware.  Additional updates outlined below are available for all Volkswagen Accessports with this new firmware.

NEW SUPPORTED VEHICLES

• 2018 USDM Volkswagen Golf GTI (MT and DSG)

Firmware will include the same Off The Shelf (OTS) Maps that are available for the 2015-17 Mk7 GTI.

2018 GTI OTS MAPS:

• Anti-Theft Mode v102
• Stage0 (Stock installed mode) v102
• Stage1 91 v102
• Stage1 93 v102
• Stage1+ 91 v102
• Stage1+ 93 v102
• Stage2 91 v102
• Stage2 93 v102
• Stage3 91 v102
• Stage3 93 v102
• Valet Mode v102

These maps now have Traction Control enabled!  This allows users the ability to limit wheel spin in racing conditions without being as intrusive as the factory traction control system.  Custom tuning will be required for optimal results but feature sampling is available in the Accessport through “Tune” > “Adjustments” > “Enable Traction Control” > and setting the value to “1.”  You can then choose the appropriate slot for the amount of wheel slip you wish to allow.

The first table shows the relationship between allowed wheel slip at certain throttle and speeds.  These values will be slot 1.  Each slot increases by 2% multiplier up to slot 7.  Slow 7 will allows a 20% multiplier of the above table between the drive wheels and rear wheels.  Slot 8 has traction control off.

Visit the Map Notes for all the details regarding power gains and modification requirements for each map.

Improvements

The code reading feature on every Volkswagen Accessport has been improved.  The Accessport will now show the generic OBDII code along with the Volkswagen specific code.
