Hey Guys
I´m using a s300 v3 in a p28 ecu.
Car runs good, but seems to have some problem with the Fuel Trim. Just look at the graph picture below.
I have to say that i have deactivated the idle control.

If anybody ever had the same problem or knows what is wrong, i would be very happy if you could help me.

EDIT: After activating the idle control, no changes at all.
