to make STFT you need to set the af#1.corrections to 1, not 0

you can t simply disable STFt and go along with only open loop
you either keep stft enable and only ltft disabled both closed and open loop, or you keep CL fuel control of racerom v10 constantly activated, already from 0.05 of engine load

you need constant instant corrections in low rpm low load due to temperature changing all the time

and as Tor said , you really need that maf scaled properly

im not sure what you mean by i simply cant disable both? you mean permanently? im just disabling both of them to scale maf and turn them back on both,or is there a software related issue with them both off


even if you mean permanently im not sure if most people realize most old cars with fuel injection used open loop with speed density some even didnt have air intake temp sensor and they worked fine in every weather and altitute, its only because of california smog cars started to have o2 sensors and then maf its mostly emission related issue than reliability
