Hello

I am a question for all chiptunner members,

when remap a car with DPF to DPF OFF, what is the right rules?

1? force regeneration with original map file and DPF filter fitted and go to 0% (or low) saturation
2? Remap the ecu with the mod map file for DPF off
3? Remove DPF filter

is ok this procedure?

how check if the file run ok? if read the saturation channel , what valour is ok? if before make the Remap the valour is 0% this valour is all time 0% or can raise with the time ? in normal TDI VAG the regenaration lamp in dashboard come on over 20% of saturation,

can any confirm this dates

very thanks

Vag with bosch ecu edc16/edc17 support switch off function, so there's no need to force regen before flash car with dpf off car
read file, flash dpf off file and there's no other procedure to do.
Vag with siemens ecu need to reset counters before flash with dpf off file, no need also here to force a regeneration (that could be very dangerous on car with dpf full)

Ok . understern

is normal that in one siemens ecu with 0% saturation before dpf off , when remap to dpf off, the saturation raise with the time?, not regeneration lamp if this value (channel 75.3) is up 20%?

best regards

If saturation raise then DPF off was not made well on file.
