    Question Disabling o2 feedback in MPTune2 T-SMEC_25_mtx_a131_mp.tpl

    I have searched turbomopar forums for over 2 hours now and found no straightforward instruction for this.

    Is it done here, or in limits?
    there are 9 adjustable cells, I don't understand the relationship between them and the respective rpm.
    I found the post where it says :"raise rich% to make it richer and raise lean% to make it leaner".
    Can someone reply which is which and maybe why to adjust this one and not that one?

    Am I using the wrong tune?

    Thx..

    Q - Is there an easy way to switch on and off O2 Feedback?

    A - For the SMEC and SBEC, set 'NoCellUpdateAboveFromMAP’ to a high value. This will essentially force the O2 control to work the same as if you were at full throttle. The other ‘NoCellUpdate***’ constants will have a similar effect. For the LM, only setting 'PWMIN_NoCellUpdateBelow_PWMIN_Pulsewidth' to a high value can disable the O2 feedback. The others will only affect the adaptive cell updates.

    I just discovered the 'sort' button.
    Sorted by group, the way it came, there was no 'nocellupdate' anything.
    I assssumed it was gone or changed.
    Thank You!
