AccessTUNER Enhancements
AccessTUNER has gone through extensive behind-the-scenes changes and is now poised to rapidly deploy new features in the very near future. In this release we have implemented some needed clean-up items to prepare for these exciting upcoming enhancements.
  • SST Table Additions - This set of new tables, such as Torque Limiter Tables and Torque Ramp Rate Tables allow fine tuning of how the throttle tables interact with engine torque requested output.
  • Table and Monitor Parity - Tables and monitors across global markets and model years have been standardized to USDM levels and provides feature, table and monitor parity across them all. Now professional tuners and enthusiast tuners will have the same features, tables and monitors, which will make it easier to tune across different regions as well as make it easier for enthusiasts to communicate across regions.
  • Added DTC Defeats (Torque Limiters) - These are new toggles that turn off annoying torque limiter triggered DTC codes that can be triggered with even slight gains over stock power levels.
  • Increased Data Precision - Data monitor and table data values were increased to 2 decimal places (hundreths) where required to improve table input and data monitor output precision.
  • v2.00 Tuning Guide - The updated Tuning Guide has been cleaned up, incorporates the new tables and has improved descriptions to better assist in tuning the Mitsubishi platforms.

v2.00 BETA Maps
New BETA Off-The-Shelf Stage1 and Stage2 maps are available for download, evaluation and feedback for all supported vehicles (does not include JDM region at this time). These BETA maps were created using the new tuning software and incorporate the latest tables, toggles and tuning strategies. Once these maps are moved from BETA to General Release, we will begin developing intake OTS maps.

Please note that these are BETA maps and may or may not perform as intended across all vehicles. This BETA release is intended to gather feedback from early adopters and incorporate this feedback into the maps prior to final release. If you are unwilling to experience potential performance inconsistencies or provide constructive feedback on these BETA maps, please continue to use the General Release maps until the v2.00 maps are finalized and come out of beta.
