Now thinking purely "hypothetically"

Back pressure. There are 2 sensors, one each side of the DPF that measure pressure difference. Keep in mind a previous burn may not complete and a full burn can take up to 50 minutes but may have paused to your driving conditions at the time.GE350 wrote: ↑Sun Mar 31, 2019 6:15 pm Just following up on this thread, I am noticing the DPF burn today occured 4 times in under a 4 hour drive!!
This seems excessive, I am confident it is right as the EGT hit over 600, the boost pressure drops and fuel usage increased.
What i want to know is there a code to adjust the differential? I am running a 3" straight from the DPF which would actually drop temps of the final probe
At this stage i will leave the DPF fitted but want to adjust frequency
any help appreciated on the exact circumstance the vehicle determines a burn
