your problem is that ecu is forcing the Fuel Injection PI ratio to 100% at idle

that usually happens normally after a cold start and last not long, before switching to 0% (so 100% DI)
the fact you have bigger injectors exacerbates this as the injection time is really short and injectors have difficult time with a so short opening time

therefore, fueling is atrocious as you can see from log
If you get to have only DI at idle as it is supposed to be, you will fix it probably
You can check it also by the value " injection mode d4-s"
when it is 1, it s like it thinks it is still in cold start mode, and uses only PI at idle
It must become 2 or 3 to be good

American tunes always have bugs like this with ecutek racerom, it's annoying a lot
I encountered this bug many times in US tunes
, and it seems ecutek don't really care about it so if you don't get to have it work correctly you can ask your tuner to force-upgrade you to Euro A02G rom that will fix any bug
