Regen cycles
2017 f350. 210k miles
I used to be able to go 500 miles consistently before regen.
Over the last 2 months it has been steadily declining and I am now down to every 200 miles.
I had a derringer tuner on and started to have the p0087 code come on and engine would derate power but it was only during a regen cycle. Took it in and injectors all passed their balance testing, they pulled sensor on the fuel rail and checked for filings, all clear.
They replaced the sensor since it was off and relatively cheap, all replaced fuel regulating valve to since it was fairly cheap and they said it can sometimes stick.
Went through another regen and it did it again and this time I was watching my idash and commanded psi was 3k higher than actual pressure. I removed derringer and it has not done that again.
But my regens are at 200 miles and dropping.
Any ideas. No codes and runs fine.

Will that affect my regen cycles dropping to 200 miles.
I have logged about 700 miles since removing the derringer and have not had low fuel pressure since.
As of now I am more worried about regen cycles.

I think it may be a little higher. I did notice that when it hits 100 it will trigger a regen then as it is heating up it skyrockets to 105 or 106 hangs there for sometime then comes down to 23 or so and shuts off.
it never did go below 20 since it was new so wasn’t to worried about that.

I had a similar problem years ago when I noticed my regens was occurring more frequent and the root cause was a defective EGT sensor was not allowing a complete regen process. Some things to consider source of fuel and summer heat can increase regen frequency.

I did not realize that summer heat would affect it. That could be it as it has been very warm and humid the past couple weeks.
I am getting fuel at the same stations I always have but who knows what quality and availability is happening nowadays.

Yep... Heat and Humidity sure does increase my regen frequency. And here in the last month, I noticed the fuel I'm getting made my engine a little noisier. So, I tried 8 oz of Power Service fuel additive and made my engine nice a quit again but did nothing on the regen frequency.

I was going to buy a derringer tuner, but after the fact that they have not answered my emails and this thread...decided not to.
the derringer tuner is supposed to optimize the fuel burn and ensure that the burn is complete which would theoretically mean more miles between regens not less miles between regens. what has Banks have to say about this? I hope they answer your emails.
if you did not have a derringer tuner, I would have suggested you clean or replace your MAP sensor.

I am not yet faulting the derringer, I removed it out of caution and one less possibility for failure right now.
while heat and humidity may play a factor I still think it more than that right now, if there were some codes I would have a place to start.
Fuel mileage and everything is normal. It went through a regen first thing this morning got down to 23 percent 65 miles later it’s back up to 47. And 13.5 mpg.

DD, I have an 9 ft enclose utility box and run mostly hw miles. Weights almost 10k lbs plus hook to heavy farm equipment and trailers quite frequently gross 20k plus lbs.
Although it’s titled a 17 I ordered it in October on the last day they closed the order banks and received it in nov. so it’s basically an 18.
So no it does not sit around.
mpg is the same 13.5 like it has always been. I did some reading on map sensors and it says if going bad and or plugged it can overload egr system it’s only $70 so I picked on up and am going to change it.
This came on just about overnight, it was a distinct change.

Anyway, curious to hear if the map sensor does it. Maybe this would be a good spare to have on hand?
