Poping decel on mustang 11-14

Whats the easy way to get a poping exhaust on decel on 11-14 mustang

Thanks

Turn off the dfco and retard the ignition timing to 0 degree in the used map point table while decel in the low load

I set the tip out spark ?tip out decel? I think it?s called to like 0 below 3500 and above idle speeds and that seemed to work. Changing dfco can increase or decrease the amount of popping it?ll do. It?s been a while though

Increase dfco enable and disable. Set enable to 55 and disable to 54 or where you want it so at 60mph or highway speeds youll still have fuel cut to help save fuel.

Yes, if you disable dfco you will dump more unburned fuel in the exhaust and cause the popping. Actually. You can control the amount of popping by retarding the timing. Log the map points used while deceleration and retard the timing to zero in the low loads high rpms. Also retard the timing in the same map points in the mbt tables to 10 degrees in the same load and rpm.

You don't have to lower mbt. During decel, timing will follow the spark decel table on 2011 to 2014. Stock, this table is set to 60* timing allowing spark up to 60* giving the torque ratio tables control of deceleration timing. Changing spark decel to 10* from 1500 to 3000 and disabling dfco will give you backfires.

Do i have to change dfco vss AND rpm AND loAd ?

On my 2014, I was able to achieve any type of snap crackle and popping I wanted (from loud backfiring to small crackles) just by tweaking the spark settings and leaving DFCO on. The key is giving spark enough authority within the torque ratio tables or your settings won't have much of an effect.

They're all thresholds. MPH, RPM, Load. One could prevent DFCO, another could allow it and DFCO will occur.
You don't have to lower load. I lowered mine to .3 because load will definitely be under that during deceleration.

True, you have to allow torque control to retard spark enough to backfire. I just never liked the sound of DFCO decel on my 12. I don't like it on the S550's either, they sound too damn smooth lol. I command decel timing.

Ok thanks a lot

Plz I need help to tune 2011 v8
Mustang
Any help
Lunch control
Pops
And fuel consumption adjust
