I will confess I haven't spent as much time with the newer models after 2015, but I have still seen it in every twin I have looked at - including the occasional newer models up to 2018. I haven't personally looked past 19 models. It also could be because I'm in California - which mostly sells only up to 91 octane. May attribute to a roughly idle. And yes, a tuner should be able to fix it.

Work with you tuner, Also since you have done the intake manifold double check for intake leaks.

update:
still not solved, also pulled code 0463 so im gonna work on that. none of the above solutions have worked, and my tuner went on a vacation apparently and has a bunch of cobb users trying to get their flex tunes up. maybe ill get a reply this weekend. is there any chance the boost controller replacing the EVAP has any effect on this? EVAP system and hoses (clamped) are still there, just not powered. |

As requested. Log file 23-23-44 showcases the issue. started data log, replicated problem and ended it. It also appears the issue only occurs if i go to neutral under 2-2.5k rpm. |

do you see that? PI switching to 100% all the time when you leave the throttle? that s the bug i was talking about you never gonna have your car idling good and smooth unless your tuner force-upgrades you and totally converts your tune to an euro tune that brings some problems, 1) i m almost sure your tuner isn t aware of this bug and doesn t carr, and he doesn t know how to force-upgrade you 2) by converting to euro tune and get away with the bugs, the fueling will be quite off, so you will require a complete new retune |

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 Last edited by tomm.brz; 04-29-2022 at 04:56 PM. |
