it s a bug in the racerom patch specifically, from around racerom 10.1 till the newest 12.3, it s present..
for the question you asked, you should ask ecutek directly and why they don t provide a fix , i don t work for them
They reverse engineer the tune from the stock directly, they do not have any help from Subaru, they find what they find. I told them via email about the bugs afflicting US tunes patched with racerom, they don t care about this car anymore.
they are based in England, and they own a Euro car.. they always defined very well the euro tunes, not so much US and asian tunes
I keep writing in this forum that US tunes are bugged since years when patcher with ecutek.. but nobody listen to me or believe me, so unless you do something against it, you will have a bugged and not smooth tune forever.. as HUNDREDS of other americans people in here that have no idea of what s happening in their car and trust tuners like Delicious
