COBB has just released new map and firmware updates for all AP-SUB-003 AccessPORTs that fixes a map issue for the 2013 WRX, STI, and Forester XT that can cause the vehicle to show a P0605 ROM Error with Stage 2 mapping. To prevent this from happening or to resolve a current issue, first you will just need to uninstall the AccessPORT from the vehicle using the Uninstall option from the main menu. Then, update the AccessPORT to the latest firmware (220.127.116.11-5151 or greater) using AP Manager. Finally, do a full Reflash map change with the newest maps on the AccessPORT or downloaded from the Maps section of our website. You can verify your current firmware by going to AccessPORT, then About and you can verify your current map version by going to Tune, then Show current Map, then Reflash Map.
For the 2013 STI, use Stage 2 map version v321 or greater. For the 2013 WRX, use Stage 2 stock intake map version v301 or greater or Stage 2+SF/AEM map version v312 or greater. For the 2013 Forester XT, use Stage 2 map version v311 or greater.
