i think it's hard coded into ecu logic

Like Before it warms up, the ecu will force switching to 50/50% PI/DI during idle and overrun

i would just deal with it

it should fully work 100% DI all the time once car is hot, at least it worked for me years ago
I wouldn't be surprise also if it's a Racerom bug in your case


EDIT: just saw now lol, you have B01C ... US tunes are super bugged with latest racerom
Switch to A02G or A01G and everything will run much better
I saw that behaviour multiple times while helping guys here, and they all were fixed by converting to euro tune

If you're boosted , US tune produces strange offsets and compensations, so that when you switch to an Euro rom, it requires a full retune because maf will be much different
