I was doing some stuff for myself and i had to make separate file of dpf off...long story short - i've attached modified BIN file that have DPF removed. If you gonna use it - PLS REMOVE DPF physically also make sure sw version is compatible with your car.
Manual work, not Volta or DPF Remover. Changes made by looking at 147 sw version that doesn't have DPF and appropriate changes were made to 2.4 sw.

It is not tested by me, i don't own 2.4. But changes are good. But may not be all that must be done to it to fully get rid of dpf functionality.

It have changes to the following maps (addresses is for other sw version - so ignore addresses):

PS pls keep in mind that it may require disconnecting dpf pressure sensor. Also i think it still could count dpf soot level, so it may not be at 0%. I for my 2.0 jtdm did MUCH more modifications to fully disable dpf, and im not 100% sure these mods in this file is enough, but for someone who just starts-it's very good starting point :)
