Thanks for the tip; I was thinking along those lines but the latest bundled definitions don’t seem to include any 2015s and I’ve been looking around on the rom raider forums and git hub. Just wondering if things stalled on the newer models. I have a 2015 2.5 forester too and haven’t seen a definition for it either. I guess I’ll keep looking I was just thinking that since others have tuned there 6 gen here after pulling via ecuflash there must be a definition somewhere.
