Hi everyone, I need help tuning close loop at idle, I have installed odb2 wifi with iPhone running dashcmd to view the Fuel trims and open and close loop status . I have been reading URD U-tune manual for guidance but in practical it is a little complicated. My fuel trims at idle are around this STFT is +03.1 - LTFT +04.7, I have tried dialing the cell as the u-tune , tried 9.4 up to 10.3 but I don't seem to get them to 0 or to a - number to close. I was hopping to manage this so I move to other cells. Can anyone help me on to get this right. My vehicle is standard FJ cruiser V6 1GR-FE , 4.0*L (3956 cc)
