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.

I just sent my PCM out this week. I should have it back next week, and I will post the stock file. Can you share that Roush file for myself and the person who commented above who is about to do the...
Once I send my PCM out, I will surely post it. It's gonna be a few weeks because I can't afford to have the truck down currently.
Yup it does need the PCM service. I'm going to send mine out soon, and I'm happy to provide a stock read to the repo. Worst case, I'll have the dealer flash the Roush tune when I buy the blower kit,...
Does anyone have the off-the-shelf Roush calibration for a 2021+ F150?
I have a customer car that is stumping me. Regular driving is fine, and wide open is fine. But he said if he's cruising on the highway and gives it about 50% throttle, it behaves weird. It is like it...
No such luck yet unfortunately :/
Right. I have never seen anything like this before myself.
Unfortunately, it didn't start at any particular time. My friend just bought this car, and it has had this issue the entire time. I...
I have not yet. I just sent him a new file with your suggestion to try. He's out of town until next week so he's gonna try it next week.
No. As I mentioned above, there was no change with the DFCO settings you recommended. I attached the log. As you can see, off-throttle the timing goes to around 20 degrees (which is close to the...
No change. Same deal. Timing off-throttle goes to 20 degrees and just stays there. Doesn't ramp down at all, and doesn't enter DFCO.
I'll give it a shot
I did the same on a friend's C6 and his just goes down to the minimum and enables. In this car I'm having issues with, it doesn't pull timing at all. It's not like it pulls down to the minimum but...
This would enable your LTFT idle cells at any speed so long as you're not on the throttle. I don't understand why this would enable DFCO.
