I second this. However, it is possible to get rid of it almost entirely. It just takes a long time. Get your fueling dialed in first (VVE and MAF), and then see what torque management is doing. One...

No cats at all
I actually ended up doing a video on this for my YouTube channel:

Right, and Roush sells a kit with a calibration for 21-23 models...
That is not relevant to this thread. I'm looking for a 21-23 Roush file...
I'm not looking for help with a 24. My F-150 is a 2021.
That would still be helpful because I could start from those speed density tables and dial it in from there. If you don't mind posting that file :)
Well my truck is a 2021, and I'm looking for a Roush calibration file still. I know someone else commented about a 2024, but that's not why I started this thread.
How would we gain access to it?
Yeah I lowered it to 0.050
Mine was 0.9. I tried raising it a bunch and I've tried lowering it down to something like 0.2. Neither change seemed to make a difference on my car. I suspected I might have had the concept...
Yeah I wish we had some more control. I'm sure there is some way to control it that HP Tuners just hasn't exposed to us via the DFSO parameters. Frustrating. I ended up setting the Ramp on Rate to 50...
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...
Bumping this thread. Still haven't figured it out.
I got it. It was the APP enable parameter. I set that to 0% so that it allows for burbles whenever. Then I just use the RPM parameters to enable/disable. Seems to work now. One other thing I figured...
I was having this same issue trying to figure out how to slow down the DFSO entry and/or command lower target torque on my Mustang. It's a 2015, so it doesn't have the burble tables. I have a...
Does anyone know what the APP parameter is? The only thing I can think of is that I don't have the right values for that parameter.
Isn't the whole point of the burble logic that you don't need to disable DFCO?
Yeah I'm not sure how a full write would change anything. The Ramp on Rate is part of the Calibration, so I doubt it's that. I'm thinking we either don't understand that variable or maybe there's an...
Update: This doesn't seem to work. I put 4.5 in there, and I still had no change. 4.5 seconds would be a long transition into DFSO and should in theory lead to a ton of pops. Yet, in my log, I see my...
Perfect! It didn't have a description in VCM Editor so I didn't know if the value I was putting in was 'seconds' or like the torque rate reduction or something. That's exactly what I needed. Mine was...
Can someone explain the Ramp on Rate parameter to me? Does increasing it or decreasing it make DFSO come on quicker? I'm trying to do a mild burble tune on a 2015 Mustang while still leaving DFSO...
For the life of me, I cannot figure out how to get the Burble logic in the Ford ECM to work. I started with settings from a 2019 Bullit Mustang. I had to modify a few things but I cannot get any...
Hey all. I just got my PCM back. Here is the stock calibration! The truck is a 2021 F-150 with a Coyote.
