Uninstalling BETA Firmware and Mapping

If you wish to revert a current BETA calibration to the older BTv101 mapping, Please follow these instructions. These instructions must be completed in their entirety or the conversion will not be successful.

Current BETA maps can be reverted to an earlier version by opening and saving the current version maps with an previous “release” version of AccessTUNER to re-generate v101 style mapping.

• Step 1: To revert to previous final release of AccessTUNER Race, navigate to the ‘Help’ tab > ‘Updates’ > ‘Check for Updates’ > Uncheck “Beta Software” box > ‘Get Updates’ > Verify version number.

• Step 2: To convert the calibration to a previous non-BETA release version, open the map to be converted in the non-BETA version of AccessTUNER. Prior to re-saving the map, it is critical that users go to “Options” –> “Display” and make sure “Keep Non-Table Data” option is unchecked. Once this is done re-save map.

• Step 3: Flash the converted map to your car. Step 2 and 3 must be repeated for every map you wish to convert and use on your vehicle. This process only needs to be performed if you wish to use non-BETA calibrations.

To update your current BETA AccessTUNER created maps Using 1.8.6.0-2280 or newer, load a map, go to ‘Edit’ > ‘Configure Options’ > ‘Display’ Tab and make sure the “Keep Non-Table Data” check box is unchecked. Next re-save your map then flash the fixed map to your car.
