DPF Question

I have two questions. The second all depends on the answer to the first so I'll hold back on asking it.

1. How does the truck know to go through a regen? Some guys get different distances between regens so it must be some variable instead of a set amount of miles. So what tells the truck to start wasting my fuel?

the amount of soot collected...there are sensors that measure restriction and know when to turn it on. Sensors can go bad though.

Thanks ChargersFan. That's what I suspected. So now, question 2.

2. If the restriction is picked up by the sensors, why does one really need a programmer for a DPF delete? I see the DPF delete pipes have ports for these sensors but if the DPF is gone, so are the restrictions. In theory, if there are no restrictions like a sooted up DPF, the truck "should" never go into regen. What am I missing here?

I believe there is a "default" in the program and it will want to regen after "X" amount of miles driven. Once it does, it will STAY in regen, therefore the need for the programer.

Correct, if the system doesn't call for a regeneration because of back pressure, after a period of time or miles the computer will initiate one anyway. The regeneration will not shut off untill exhaust sensors determine a certain heat level has been obtained which will never occur if the DPF is gone.
The bottomline is, if you remove the DPF without shutting off the regens with a programmer, it may run fine for awhile but eventually you will enter "regeneration hell"

I believe 600 is the maximum number of miles before it will automatically go into regen and stay that way if you remove the dpf w/o a tuner.

A rule imposed to protect the planet from pollution they say.
Yet it uses twice as much fuel, so does twice the harm.
If the government stayed out of the peoples business, the world would be a much better place.
