COBB Tuning Smashes Through the MAZDASPEED3/6 LOAD CAP Barrier!

COBB Tuning is proud to announce updates to the MAZDASPEED AccessTUNER engine management software and Off-The-Shelf maps that remove the Load Cap roadblock to producing prodigious amounts of horsepower and torque while still providing all of the sophistication and safety inherent in the stock ECU.

COBB Tuning continues to push the envelope in stock ECU engine management control by removing the “load cap” that has prevented enthusiasts from achieving maximum gains from larger than stock turbochargers. Through ongoing ECU discovery, software development and internal and external testing, COBB Tuning has created a tunable solution to alter the load cap parameters, allowing Professional and Enthusiast tuners to break through the 400whp barrier within the stock ECU!

An all-new version of AccessTUNER is now available for download from COBBTuning.com and features this new “load cap” removal as well as other new features that simplify and speed up the tuning workflow.

CALCULATED LOAD MAX
Max Load adjustment tuning has been added into AccessTUNER Race and Pro to compensate for how much air (gram/cyl) the ECU will recognize. This is a critical parameter for higher HP applications due to the fact that the ECU is not able to properly calculate fuel requirements when demand exceeds the load cap. If the load cap is set too low, a lean condition occurs, getting worse as the delta of actual load goes further beyond the load cap.

COBB Tuning has added two new tables to AccessTUNER, called Calc Load Max A and Calc Load Max B. These are RPM referenced tables with a value that presents a max allowed value for the airflow portion of the Calc Load. Altering these tables effectively allows the tuner to increase the maximum load values allowing for more airflow and proper fueling.

NEW FEATURES
COBB Tuning’s AccessTUNER engine management software for the MAZDASPEED now includes pass-through tuning, which allows the user to flash maps from a laptop computer directly to the ECU. All AccessPORT users can now switch their AccessPORT to “pass through” mode to directly interface with the ECU from their laptop. This also allows users to view live ECU data and Datalog directly to their laptop. Users can set and view live ECU data parameters from their laptop for seamless data viewing and acquisition.

UPDATED OTS MAPS
COBB Tuning has also released updated Off-the-Shelf (OTS) maps with the load cap removed and these are available for download from our AccessPORT Map Database. All OTS maps have been upreved to v1.05 for MAZDASPEED3 and v1.07 for MAZDASPEED6. These new maps are also bundled with the latest firmware update, allowing users to update their OTS maps through a firmware update using AccessPORT Updater.

COBB Tuning continues to be an innovator in the MAZDASPEED tuning community with ever more powerful tuning solutions and features that allow MAZDASPEED enthusiasts to get the most out of their vehicles while retaining the advanced logic, sophistication and safety of the factory ECU.


FULL RELEASE DETAILS
AccessTUNER Engine Management Software

Max Load adjustment tuning has been added into AccessTUNER Race and Pro to compensate for increased airflow (gram/cyl) the ECU will recognize. This is very critical for higher HP applications due to the fact that the ECU is not able to properly calculate fuel requirements when cars are exceeding the load cap. This may create a lean condition, getting worse the larger the delta of actual load gets above the load cap.

Two new tables have been added labeled: “Calc Load Max A” and “Calc Load Max B.” These are RPM referenced tables with a value that presents a max allowed value for the airflow portion of the Calc Load.

Availability:

New Features:

  • New Load Maximum Tuning Logic
  • Two new tables: “Calc. Load Max. A” and “Calc. Load Max. B” which allows the ECU to implement a fueling load cap limit on the vehicle. This load cap has only to do with the fueling calculation capabilities of the ECU.

Updated New Table documentation for Load Max Tuning:

  • Calc. Load Max. A
  • Calc. Load Max. B
  • Simplified Connect to ECU Workflow
  • Quicker connection rates
  • Directly start datalogs and dashboard without connecting to the ECU first
  • Allows for configuring datalogging and dashboard parameters without being connected to the ECU.
  • Pass-Through Tuning
  • Improved tuner workflow by by-passing necessity to use AP Manager
  • Connect the AP to PC via USB cable and AP to car via OBD cable.
  • Allow the AP to boot to main menu (AP must be in main menu in order for any pass-through tuning to work, AP will show a busy-screen when it’s in Pass-Through Mode.

Flash Map:

  • Removes the necessity from having to use AP Manager to transfer maps during tuning.
  • Instructions: (Once AP is connected to PC and car – a.k.a. Pass-Through Tuning)
  • Once you are ready to flash a map (created new map in tuner or loaded a map in tuner), ensure the AP is fully booted up and at the main menu.
  • Then select ECU–>Flash Map from the tuning software menu.
  • Follow the directions relayed from AccessTUNER to finish the flash process. (When to key on/off, when to not interrupt the flash process, etc.)

Datalogging & Dashboard:
Instructions: (Once AP is connected to PC and car – a.k.a. Pass-Through Tuning)

For Dashboard

  • Configure parameter list in Tuner select Options–>Configure Options menu.
  • From tuner select View–>Dashboard

For Datalogging

  • Configure parameter list in Tuner select Options–>Configure Options menu.
  • From tuner select ECU–>Datalogging

AccessPORT Firmware

Availability:

New Features:

  • New Base Maps: increased load fueling cap to the max. allowed value.
  • Maps are available with this firmware update or can be  downloaded from the MAZDASPEED AccessPORT Map Database.
  • v1.07 maps for the 2007-2009 MS3
  • v1.05 maps for the 2006-2007 MS6
