    18 and up Mustang Gt Burble

    Has anyone done anything with the burble tab to add some pops on decel and in between shifts? Have a Customer that I have tuned his 19 and wants me to add that. Just looking for a bit of info how to increase the intensity of he wants it more aggressive. I see the bullit file is different with it then the normal Gt file.

    The bullit is factory enabled but it does not burble much with stock settings. You can lengthen the time and how easy it enables, but as far as between shifts I don't know, I've only played with it on my 10speed auto.

    So I tried the bullet settings and lengthened the times a bit hoping it would pop some. It didn’t, so I went back to the method of how I usually set of the spark tables to pop. Set my mbt tables From .20 load and under to 10
    Degrees across the board. Pops just like he wants but now he said he noticed the auto rev match does not function now. Could that be due to how I have the spark tables by any chance does anyone know?

    You need to adjust dfco in the fuel tab and dfco in the torque ratio tables.
    Stock settings will have timing too advanced during decelerstion or on between shifts. It could be 30 to 50*. Mess with the ratio tables to get spark less advance until you get the sound you want .

    Once I made the changes I stated in the spark tables it gave him the sound he wanted , although I was trying to make the burble tab do the work instead. The issue now is after I nodded the spark tables his rev match does not function anymore. Trying to see if it’s a fluke thing or if changing the spark tables would have any affect on that which I’m doubting.

    Burble logic - works just fine. Play with setting a little it will do what you need.

    I’ll keep trying just wish this car was closer to me so I could have more time to get this down. So if I wanted to increased the speed of how it pops and so on would I increase the duration in time or lower it?

    Don't go too far with burble or you will end up destroying your cats.
