i've been datalogging today and last night and i'm getting knock retard at low rpm low throttle and slight load like small inclines and such. WHY? full throttle no retard. and one more ?? i just installed new injectors when i'm tunning for the primary ve do i need to disconnect the maf or can it still be connected?
