Software affected:

• 2.0.0.0-16211 and newer

In previous versions of the software you may have seen some issues with the Wastegate Compensation modes.

In certain instances even with the master switch disabled for the CCF base tables controlling Wastegate Duty Cycle (WGDC) Compensation, the software would still sometimes use those base tables and compensations.  The problem will typically present itself when using the OEM duty cycles in order to control the wastegate and you find that your Wastegate Duty Cycle is higher or lower than expected.  The Fix for this issue is going to be to download the latest build of Accesstuner and simply re-save the map in the software.  No other tweaking or tuning will be necessary.
