2010-2014 GTI Accessport & Accesstuner Updates - New OTS Maps, Tables, and Monitors

***UPDATED August 4, 2016***

Edit: There was a minor issue in the July 27th release - Engine On/Off Detection was defaulted to Off. Firmware version 1.7.3.0-12911 addresses this issue.

Our Volkswagen team has been working on map, firmware, and software updates for currently supported 2010-2014 Volkswagen GTIs. Most notable for end users will be new (v103) Off The Shelf Maps, added monitors, and minor updates to our Accesstuner software.

v103 Off The Shelf Maps
This new iteration of OTS maps utilizes updated MAF compensation logic with the use of newly added tables. This is particularly important for vehicles with the COBB Big SF Intake and should clear up issues with high fuel trims when using the Stage1+SF or Stage 2 maps. The v103 maps also include some minor updates to fueling logic which should lead to more consistent fueling across the board. Additional information regarding these maps can be found on the Map Notes Page. Maps can be accessed by updating Accessport firmware to 1.7.3.0-12873(or newer ) or by downloading maps directly from the Maps Section of the COBB website.

Accessport Data Monitor Changes
In our continued effort to develop the most versatile tuning solution for the Mk6 GTI, we have added new monitors and made changes to existing monitors as seen below.

New Monitors:
  • Injection End Angle
  • LPFP Pressure Request
  • Requested Load
  • MAF Period
  • Throttle Pressure Ratio
  • LPFP Actual Duty Cycle
  • MAF Correction Map Interpolation
  • MAF Corrrection Factor
Updated Name and Precision for:
  • Rail Pressure Actual
  • Rail Pressure Maximum
  • Rail Pressure Target
  • Rail Pressure Commanded
Removed Monitors:
  • Manifold Air Temperature
Accesstuner Software Updates
To go along with the updated monitors in Accessport firmware, the Accesstuner software sees similar updates along with a group of new tables. The Volkswagen Accesstuner welcome screen also has a minor update to a new image file. To utlize these updates, ensure Accesstuner is on version 1.9.1.0-12873 or newer.

Table Additions
  • HPFP I Component
  • HPFP P Component
  • LPFP Maximum Duty Cycle
  • AFR Correction (efficiency)
  • EGT for Component Protection Activation (Fuel)
  • EGT for Component Protection Activation (Ignition)
  • Mass Flow Across Throttle Blade
  • MAF Scaling Table
Increased Table Limits
  • Lambda for Component Protection
  • Lambda for Component Protection with Tumble Flaps Open
  • Time Constant for Slow Boost Pressure Regulation A & B
New Monitors
  • Injection End Angle
  • LPFP Pressure Request
  • Requested Load
  • MAF Period
  • Throttle Pressure Ratio
  • LPFP Actual Duty Cycle
  • MAF Correction Map Interpolation
  • MAF Corrrection Factor
Updated Monitor Names
  • Rail Pressure Actual
  • Rail Pressure Maximum
  • Rail Pressure Target
  • Rail Pressure Commanded
Removed Monitors
  • Manifold Air Temperature
Updated Accesstuner Welcome Screen

*****Archived Updates, current release can be found in Post #1*****


In an effort to offer the most comprehensive tuning solution available for the Mk6 Volkswagen GTI, we are excited to announce our first major update to Accessport firmware, Accesstuner, and Off The Shelf Maps for the 2010-2014 Volkswagen GTI.



Accessport Firmware Updates (1.7.3.0-12306)

Firmware updates to the AP3-VLK-001 Accessport consists of new Off The Shelf Maps and various updates to Monitors available for live viewing and data logging. In order to update Accessport firmware, download and install Accessport Manager.

V102 Off The Shelf Maps

While calibration data in the v102 maps remains the same, there are some minor updates to all map files including minor bugs in descriptions and correcting torque reduction requests on the 115AS ROM. A complete list of changes can be found on the Map Notes Page.

Map Files Available:
  • Anti-Theft Mode v100.ptm
  • Stage0 v100.ptm
  • Stage1 91 High Boost v102.ptm
  • Stage1 91 v102.ptm
  • Stage1 93 High Boost v102.ptm
  • Stage1 93 v102.ptm
  • Stage1+ 91 v102.ptm
  • Stage1+ 93 v102.ptm
  • Stage2 91 v102.ptm
  • Stage2 93 v102.ptm
  • Valet Mode v100.ptm
Accessport Monitor Updates

Additional monitor conversion support:
  • "Torque (Actual)" now converts from nm to ft-lbs
  • "Rail Pressure" now converts from MpA to PSI
  • "Airflow Rate (Nominal)" now coverts from dm3/s to ft3/m (CFM)
  • "Fuel Flow" now coverts from ML/s to G/m
New Monitors:
  • "Pre-Throttle Boost Pressure"
  • "EGR Filling"
  • "EGR Pressure"
  • "Filling to Pressure Factor"
  • "WGDC PID Result"
  • "WG CAN Target Pressure Ratio"
Other Updates:
  • Added "AFR Commanded" (Final)
  • Updated AFR monitors precision from 3 to 2, changed name of "Target Boost" to "Target Manifold Boost".
  • The Boost Monitor is now based off of Pre-Throttle Boost Pressure for improved accuracy.
  • Boost Error monitor corrected to display correct value.
  • "WG I Factor" & "WG P Factor" monitors corrected to display the correct value.
  • Removed superfluous monitors: "Target Boost Pressure (Filtered)" and "Target Boost Ratio"
For a complete list of Volkswagen Monitors, see the Volkswagen Monitor List.
