Our Mazda Experts have been at work in recent months to bring some much needed updates to the Mazdaspeed Accessport, Off The Shelf Maps, and Mazda Accesstuner software.

Mazdaspeed Accessport Firmware Updates (AP3-MAZ-002)

The following updates can be found on Version 3 Accesssports utilizing firmware version 1.7.3.0-13871 or newer.  To update your Accessport, connect it to a computer with Accessport Manager installed and follow the steps outlined on this page : STEP-BY-STEP FIRMWARE UPDATE INSTRUCTIONS

Added Idle RPM Adjustment Capability

Creating additional vacuum at idle can help to subdue an exhaust smoking problem that is common on Mazdaspeed vehicles. With Advanced Tuning Settings activated on V3 Accessports, users will now see an option to adjust idle RPM in 50 RPM increments with a range of +/- 300 RPM from the initial idle value.  Once enabled, users will be prompted to adjust the Idle RPM during a Map Change.  Most have found an increment of 100-150 RPM addresses issues with smoking at idle.  Please note, adjusting the idle values too low may prevent the car from being able to maintain idle.

Updated Off The Shelf Maps

Some Mazdaspeed owners have reported overboosting issues on cars with upgraded turbo-back exhausts.  This primarily occurs during winter months when air density reaches higher levels.  Previous updates added the ability to manipulate Wastegate Duty Cycle on the Accessport in an attempt to bring boost levels down.  For this update, we’ve taken it a step further.  All Stage 2 and Stage 3 Off The Shelf Maps have been up-revved to improve compensations during those colder months and now feature a closed-loop boost control tuning strategy which will improve boost control year-round, regardless of temperature.   The following map files feature these updates:

USDM Vehicle Applications:

• Stage2 91 v250.ptm
• Stage2 93 v250.ptm
• Stage3 91 v250.ptm
• Stage3 93 v250.ptm

WM Vehicle Applications:

• Stage2 95 v250.ptm
• Stage2 98 v250.ptm
• Stage3 95 v250.ptm
• Stage3 98 v250.ptm

Mazda Accesstuner Updates

Both Accesstuner and Accesstuner Pro are receiving updates that we have rolled out across other platforms recently.  Software version number 1.9.1.0-13871 and newer will include the following updates.

Enhanced Map Compare Feature

The Map Compare feature for Accesstuner receives some handy updates with this release.

First, a Comparison Summary is now displayed after comparing two map files which will list the tables that have differences.

Next is an Accesstuner Pro-only feature: the ability to “Compare to Other Stock” which allows COBB Protuners to compare factory data across model years to see calibration changes the manufacturers have made.

All Accesstuner users now have the ability to Import Map Properties along with the calibration data in tables desired.  This allows users to import map descriptions, revision numbers, and AP Serial Numbers.

An additional useful feature is the ability to Import Tables either from an alternative map file or from a stock calibration file.  Once a map has been selected, users can select which data to import from that particular file.

Load Map from ECU Selection Panel

An improvement to the ECU Selection Panel now allows users to load a map file before having to choose an ECU type.  This can be convenient for Protuners who need to make updates to a custom tune file where the file name does not indicate the exact ECU type.

Miscellaneous Table Fixes

An assortment of tables have been updated to address minor bugs or incorrect descriptions.  Tables that have been labeled as “BETA” no longer carry that tag as they have been verified using internal and external testing.
