Posted by Travis on 14 Sep 2011 | Tagged as: 135i, 335i, 535i, AccessPORT, BMW, Calibrations, Firmware Update, Product Updates
COBB Tuning is proud to announce new calibrations for BMW 135i, 335i and 535i turbocharged performance vehicles. In response to customer feedback, all BMW AccessPORT calibrations are offered with increasing levels of performance. Maps are now available in Drive, Sport and Aggressive configurations. This will simplify AccessPORT map selection and allow drivers to easily tailor their AccessPORT calibration to their specific driving style and performance needs. In addition, expanded throttle mapping options are available and each map includes improvements to power delivery. The latest firmware adds support for the latest ROMs discovered in the field.
Introducing BMW’s New Calibration Line-Up
COBB Tuning introduces a new calibration strategy for AccessPORT equipped BMW’s. This new calibration line-up gives drivers a choice of performance level within the Stage1 maps. Based on feedback from BMW AccessPORT users, one size does not fit all BMW drivers. In addition to offering four different throttle profiles to suit driver preference, COBB Tuning now offers three levels of performance to suit each drivers’ exuberance!
All map performance levels and throttle profiles can be downloaded from the BMW AccessPORT Map Database.
Improved Throttle Mapping
All of our new AccessPORT calibrations feature improved throttle mapping for smoother power delivery and less, on/off feel. This will give your BMW a smoother, more linear feel while still giving that increase in power that enthusiasts desire. All AccessPORT mapping is now available with four different throttle calibrations to give drivers the throttle feel that best suits their driving style.
New Rom Support
COBB Tuning is always adding new support to the BMW AccessPORT. With this update, new ROM support is available for previously unsupported 2007-2009 BMW 135i, 335i and 535i vehicles including “is” and “xi” models. If you encounter a ROM that is not recognized by the AccessPORT, update to this latest firmware as we may have recently incorporated support for your ECU. If your ECU is not recognized using this firmware, please notify us promptly so that we can get you into the BMW AccessPORT family ASAP!
Bug Fix
The v300 maps revealed issues some customers have experienced, such as a possible limp mode when accelerating hard at higher rates of speed and slight surging at part throttle when the motor is cold. A torque limit threshold was adjusted to eliminate the potential limp mode and a fuel based load compensation was changed to smooth out the partial throttle drivability.
These new BMW performance calibrations and ROM support for your COBB Tuning AccessPORT are available for download or via our latest AccessPORT firmware update. To update your AccessPORT to the latest firmware, simply open the AccessPORT Manager application, connect your AccessPORT to your computer via the supplied USB cable, then click on the “Updates” menu icon and follow the on-screen prompts. These new features will be installed automatically. If you do not have AccessPORT Manager, you can find the download link for your free copy on our Support Page. To complete the update, flash one of the new v3.01 calibrations to your ECU. Using older maps with this update may cause poor performance or unexpected issues.
Posted by Travis on 31 Aug 2011 | Tagged as: AccessPORT, Calibrations, Mazda, MAZDASPEED3, MAZDASPEED6, Product Updates

COBB Tuning is happy to announce new features and calibration updates for all MAZDASPEED vehicles. This update includes Boost Tuning for 1st Gen (2007-2009) MAZDASPEED3s, Launch Control and Flat Foot Shifting enabled for 2nd Gen (2010-2011) MAZDASPEED3 and Fast Data Logging for all MAZDASPEED3s and MAZDASPEED6s. Boost Tuning logic for the MAZDASPEED6 is still in development and will be released at a later date.
These features are available through a combination firmware updates and new maps. The updated maps for the MAZDASPEED3 are available for Stage1 and Stage2 cars with the stock intake, the COBB SF intake and several other intakes as well as calibrations for turbo inlet pipes, intercoolers and other go-fast, bolt-on parts. Now every model year of the MAZDASPEED3 line-up has over 110 Off-The-Shelf maps to choose from, making the AccessPORT the leader in plug-and-play ECU tuning!
Boost Tuning
COBB Tuning is the leading innovator in MAZDASPEED3 aftermarket performance ECU Tuning. Our proprietary industry-leading Boost Tuning logic has performed extremely well on the 2010-2011 MAZDASPEED3 vehicles. Over the past several months we have offered Boost Tuning calibrations and tuning software in BETA format for the 2007-2009 MAZDASPEED3 with very positive results. These calibrations are now available in final release form, giving 2007-2009 MAZDASPEED3 owners the superior performance of Boost Tuning and over 110 maps to choose from! In addition, current non-boost tuning calibrations can be converted via AccessTUNER for better boost control.
The stock ECU logic uses load targets to determine power output and dynamically adjusts boost pressure to meet those targets. Early on, COBB Tuning recognized that this was a cumbersome way of controlling boost and could result in erratic boost control and sub-optimal performance. To rectify this, COBB Tuning developed new logic instructing the ECU to target boost instead of load.
This “Boost Tuning” strategy allows for much more consistent boost control for a more linear and consistent boost curve which means improved power delivery for your MAZDASPEED vehicle. Boost Tuning on the OEM ECU is ONLY available on the COBB Tuning AccessPORT.
Launch Control and Flat Foot Shifting
COBB Tuning is pleased to announce the availability of Launch Control and Flat-Foot Shifting for 2nd Gen (2010-2011) MAZDASPEED3s. Launch Control limits engine RPM to a user-set value when launching to build boost and increase launch consistency. Flat-Foot Shift allows the user to maintain wide-open-throttle during gear changes, keeping partial boost between shifts and improving acceleration post-shift.
This firmware release enables Launch Control and Flat Foot shifting on 2nd Gen MAZDASPEED3’s and sets the limits at the factory rev limiter. The latest release of AccessTUNER software allows the Launch Control and Flat Foot Shifting limiters to be adjusted and saved in the map. Click this link to learn more about the latest MAZDASPEED AccessTUNER release.
Fast Data Logging
This update also includes Fast Data Logging for all MAZDASPEED AccessPORTs. Faster datalogging means more resolution in data logs, allowing users to see how the engine is behaving during high-speed and high-load conditions in greater detail. The Fast Data Logging feature is built into the latest maps for the MAZDASPEED3 and MAZDASPEED6 are available now for download. This feature applies to both v2 and v2b AccessPORTs.
Compatibility Update
An incompatibility exists between previous versions of our maps and the latest AccessPORT firmware release for the MAZDASPEED vehicles, which will lead to improper readings through the AccessPORT’s Live Data and/or Data Log features. In order to resolve this issue, please be sure to follow the steps below for the scenario that most closely matches your situation. To use these latest calibrations your AccessPORT must be updated to Firmware Version 1.6.4.2-2553 or later.
If you are using calibrations made with older versions of AccessTUNER or wish to use an older Off The Shelf calibration please update your calibrations using the following steps. Please be sure to download and install the latest version of AccessPORT Manager 2.0 before following any of the steps listed. Maps must be open and saved with AccessTUNER version 1.8.6.0-2517 or later to resolve compatibility issues.
* Updating when utilizing the latest Off-The-Shelf (OTS) calibrations
* Updating when utilizing an AccessTUNER Race custom tune or old revision OTS calibration
* Updating when utilizing an AccessTUNER Pro custom tune
We would like to stress that if you are using an old version of one of our OTS calibrations or an AccessTUNER Race custom tune with a new AccessPORT firmware revision, you can resolve this Data Log/Live Data issue by re-saving your map through the latest version of AccessTUNER Race, then flashing the newly saved map to your vehicle.

COBB Tuning has just released a new AccessPORT BETA firmware update for 2010-2011 MAZDASPEED3, 2007-2009 MAZDASPEED3 and 2006-2007 MAZDASPEED6 vehicles as well as a BETA update for AccessTUNER Race and AccessTUNER Pro tuning software. These are far reaching changes that include Launch Control and Flat Foot shifting for Gen2 MAZDASPEED3’s, the introduction of Boost Tuning for Gen1 MAZDASPEED3’s and improved datalogging speeds for all MAZDASPEED3 and MAZDASPEED6 vehicles. The details for each vehicle type are shown below:
Launch Control & Flat Foot Shifting (2010-2011 MAZDASPEED3)
Launch Control and Flat Foot Shifting features are now ready for beta testing on the Gen2 MAZDASPEED3. The beta firmware includes Stage1 and Stage2 maps for the stock intake and the COBB SF Intake with Launch Control and Flat Foot Shifting enabled (using the default rev limiters). These features can be adjusted using the latest version of AccessTUNER Race software. Any Off-The-Shelf map or AccessTUNER Race customized map can be updated to use Launch Control and Flat Foot Shifting simply by opening the map in AccessTUNER Race 1.8.6.0-2212 or greater, resaving the map and then flashing the map to your ECU. Pro tuned maps must be updated by a Pro Tuner using AccessTUNER Pro 1.8.6.0-2212 or greater at this time.
Boost Target Tuning Logic (2007-2011 MAZDASPEED3 and 2006-2007 MAZDASPEED6)
COBB Tuning’s proprietary Boost Target Tuning Logic offers more consistent boost control for better performance in all gears compared to Mazda’s Load Target boost control. AccessTUNER software updates several boost control table changes and all new wastegate tables to allow even more refined Boost Target tuning control. Any Off-The-Shelf map or AccessTUNER Race customized map can be updated to use Boost Target logic via AccessTUNER Race 1.8.6.0-2212 or greater. Pro tuned maps must be updated by a Pro Tuner using AccessTUNER Pro 1.8.6.0-2212 or greater at this time.
Boost Target (BT) maps for Gen1 MAZDASPEED3 vehicles with stock or COBB SF Intakes are included in this firmware release. Off-The-Shelf beta maps for several other Gen1 MAZDASPEED3 intakes are openly available for download and evaluation at forums.cobbtuning.com.
MAZDASPEED6 Off-The-Shelf BT maps are still being developed in a closed beta test and will be made available once testing is complete. While the latest AccessTUNER Race is able to create Boost Target maps for MAZDASPEED6 vehicles, it should be noted that converting a Load Target map to Boost Target map requires significant tuning changes and should only be attempted by experienced tuners. Off-The-Shelf BT maps will be available for MAZDASPEED6 vehicles soon and will make the transition from Load Target to Boost Target tuning as easy as pushing a button.
Improved Data Logging Rates (2007-2011 MAZDASPEED3 and 2006-2007 MAZDASPEED6)
Data logging rates have been significantly improved for V2 and V2B AccessPORTs using the default data logging list. MAF Voltage, Intake Valve Adv. and Intake Temp have been added to the default data logging list. The beta firmware includes Stage1 and Stage2 maps for the stock intake and the COBB SF Intake with Fast Data Logging compatible maps. Any Off-The-Shelf map or AccessTUNER Race customized map can be updated to support Fast Data Logging simply by opening the map in AccessTUNER Race 1.8.6.0-2212 or greater, resaving the map and then flash the map to your ECU. Pro tuned maps must be updated by a Pro Tuner using AccessTUNER Pro 1.8.6.0-2212 or greater at this time.
A/C Idle Control Tables (2007-2011 MAZDASPEED3 and 2006-2007 MAZDASPEED6)
AccessTUNER includes two new tables to control engine idle speed to compensate for the air conditioning system.
Improved 3D Table Graphing (2007-2011 MAZDASPEED3 & 2006-2007 MAZDASPEED6)
AccessTUNER includes 3 dimensional table graphing improvements that make the 3D graphs much easier to read and interpret.
