    15-17 Mustang burble

    Anyone know how to burble tune a 15-17 mustang? The 18+ have a bunch of burble specific settings in the DFCO section. For 15-17, would you just directly edit the Torque Ratio clips in decel regions?

    I attached it. It's just the factory Roush phase 2 tune.

    I never heard back from stephen but I found that lowering the Torque Ratio Clips under decel load increased the burble intensity. These are the Lower (Long) [ECM] 44894 and Lower (Short) [ECM] 44895 tables. However, I cannot figure how to lengthen the duration of the burbles without disabling DFSO entirely. I do not wish to do this because I do not want it to burble the entire time I'm off the gas. I just want it to burble for 2-3 seconds instead of 1 second or less when I get off the gas. Is there a way to increase this duration so that the car transitions into fuel cut slower?

    Meaning lower the advance in the corresponding MBT spark table for whatever mapped point is used on decel?

    Made some small progress. If I increase the ramp on rate to 50 and lower the spark torque reduction setting for DFSO to 0.050, I get some pops before DFSO enables. It's still weird that you can't control the DFSO entry time though.

    You can there's a scalar for it.

    The time delay. You may not have access to it.

    How would we gain access to it?
