    disabling trim updates

    tuning the ol 3v with an ngk. seems like i was supposed to disable trim adding/clipping when dialing in maf for VE stuff when using a wideband. what do i disable if so to get my maf dialed in ?

    what is an ngk?

    you dont need to disable anything to dial in the maf just simply plot the fuel error (ltft & stft) vs maf counts and dial in the maf flow
