    2018 STI with 207 swap incurable p0244

    Tuning a 2018 STI and I have two issues.

    One is I keep hitting a fuel cut around 6800rpm and popping a p0244. That's the usual overboost code but no matter what I set the Boost Limits table to, including maxxing it, I keep popping p0244 right before 7000 rpm. Any fix for this?

    My second issue is the Closed-to-Open-Loop display tables are not present so I run lean on spool up to 3800rpms. Not ideal, any fix for that as well?

    I gave up on Subaru on HP Tuners... It's never seemed ready and Cobb works.

    That said, the only odd thing I saw in your map is the WGDC dropping to 0% up top. Also, it doesn't seem to work like Cobb for Req Tq vs Req Boost in that you can't even reach the Req Tq X-axis in the Req Boost table. Have you tried rescaling the X-axis? Do you have a log comparing target vs actual?




    As seen through Cobb, where the Req Tq on the throttle map directly correlates to the X-axis on the Req Boost table:




    Sorry, I screenshot them backwards from each other.
