When you install the delete kit is there a module to fool the ECU and if so where does it mount?
Thanks in advance!

Hey Mike,
The active regen occurs when the DPF fills to a specified level. the general concensus is that this usually happens about every 400-500 miles depending on all the typical variables (load, speed, city vs. highway, big tires, etc etc etc).
When the truck goes into an active regen the EGT's will raise which is your best indication that the regen is occuring. Some have also made note of a unique smell coming from the exhaust while in regen though I myself have never noticed such a thing. Another way to tell is to watch your EVIC fuel economy readout. If you see your mileage start dropping for no apparent reason, you are likely in active regen.
There is a module that fools the ECM into believing the DPF is still present and functioning properly with a DPF delete kit. This module typically taps into the sensors plugged into the DPF and mounts to the inside of the frame so it is out of the way and still within reach of the exhaust sensors. Hope this helps.
