    Exclamation controlling the cutoff to get the boobing voice

    hey everyone
    i did tuned many cars of gen4 and gen3 and all of them responding very well.
    but i did tried today to tune 2014 sierra 5.3L , and as usual i did make changes to the cutoff tables to increase the RPM speed limiter and to get the popping noise when the pedal hitted at full throttle for a while, but in fact i did not get the results as gen4 cars the engine rpm speed hanging a little and the popping noise is a little slow.
    i did change the values of (RPM limit method delay vs gear) again from 6sec to 2sec and the popping noise speed is increase a little but still slow for my tast and didnt came as the gen4.
    so what do you think?


    updates:
    i did play a little with these tables and i get the answer and it is worked very well right now

    STEP 1/ go to engine>fuel>cutoff,dfco
    under cutoff you will found the extreme cutoff and resume adjust these two values to the cutoff that you want.
    make sure to do changes to the table of (fuel cutoff RPM vs ERT VS ECT) to match the extreme cutoff value with the plots in front of the normal operational engine coolant temp as shown in the picture down.

    STEP 2/ change the values of the cutoff RPM VS Gear. (these values must be below the extreme cutoff by 150-300 rpm)
    STEP 3/ Disable the control method as shown.
    STEP 4/ add values in sec to the switchover (RPM limit method delay VS gear) table. try 5 sec in all plots or 6 , its probably good for most cars and the speed of popping noise is great

    i hope who will try this that he will showing as the results

    i think something is lost in translation here. what country are you from? everyone knows boobs have no voice, but a picture is worth a thousand words.

    i believe what he is referring too is the popping noise

    on older gen cars having the extreme cuttoff and resume real close can exhibit that

    the guy wants to bounce off the rev limiter quick. Yes they unfortunately like to do that in this part of the world...
