Another thing i’ve stumbled in yesterday, and i’m trying to fish out the issue. Mid way mapping this 2015 STI, in which i’ve wired an Emu Black, the VE table look very odd…It looks like this, for the car to hold the Lambda Target. It’s like the ecu dose a MAP compensation (even thow the MAP comp Correction table is all 100%)
What’s your fuel system? is your regulator a 1:1 type?
Can you post the entire tune and a log? so many variables
i can send it via email, i’m not allowed yet to upload files. The fuel system is OEM, just bigger fuel pump and 1200cc deatchwerks injectors.
