I'm trying to tune my 2018 cruze I have the fuel trims, and dfco to enable at 490*. I have also tried to lower the temp and they will not turn off. I did turn off the flex fuel. I'm running the lastest beta version.
Try setting O2 readiness to low. That is the only thing I see that is allowing O2 control in your tune.
It looks like you got everything else set up. Report back and let us know.
Ok so on this one I set O2 readiness to 0mv and for the closed loop delay I set it for 32,500 sec. It stays in OL so the ltft are off but the stft are still on and working as well as the dfco.
Did you figure anything out here? I looked over the file and unfortunately nothing is jumping out at me. Maybe load stock and see if it works.
Also, any DTC's.
On my 2017 ATS, I've done the same thing and had to turn off close loop in the special functions tab under fuel. Afterwards I restart the log to get true open loop data.
