Hi Cravin,
Thanks again for using our products. The idle return issue on some maps has been addressed during the module firmware upgrade to version 4.0, which was released August 15th. I suggest upgrading to 4.0 firmware from the 3.2 that you have currently, and after clearing the learned IAC offsets in the module, run the IAC-AUTO function as described in the instruction sheet. Also, before doing this, click the [CONFIGURE] [SMARTLINK UPDATE] menus to update your SmartLink IV to the latest version (v14.16).
Once you have completed the software upgrade, you are ready to upgrade the firmware in the module. Select [Configure] [Firmware] [Check for Firmware Update] to view available firmware updates.
If more than one selection is available, pick the SmartLink IV version with the latest date. Currently named: EFI_THUNDERMAX-01_Version40_07-28-06.B19. Double click on the file to
