Default Effect of Malone stage 2 or similar tune on DPF & emissions post modification (EA288)

Its widely speculated that the EPA modification will have a negative impact on the life of the emissions components of the car.

We have no real data on this, but they don't expect the stuff to last, at least not the DPF (which can be deleted and vag-commed out I suppose)

Does the malone tune bring the levels of whatever is negatively working against these componets back to a level where they will last longer? Whats the effect of a stage 2 on DPF, if any?

I am 98% confident the Malone tune will make things all better. After I had my fix performed I re-applied my Stage 2 tune and my car is running like a champ again.

I am in no way shape or form the most knowledgeable person here so if I am wrong someone will correct me.

That tells us nothing about the OP's original question though.

I'm not sure any one can or will answer it with actual data or reasoning

Sorry was taking the piss a bit...
It is a tall order to fill. IMO best answer will be informed speculation of course, but really only time can tell. There are so many factors involved. I would think you would need control groups to report findings over time, equipment to pull data, a complete diagram of the Malone mapping, models/model years that are in question (all I assume). This forum would be the best hope to gather all that. Sure someone with engineering experience and all the data in hand can probably give a decent estimate.

The fix was accomplished with an ECU update. I have to believe replacing much of that update with the Malone tune is going to ease the burden on the equipment, if in fact the emissions fix is expected to further burden the emissions equipment. I had not heard that it would or could until now but It makes sense

Im not sure if they expect it or not, but I would expect at least the DPF to suffer. Also probably the urea system since it is in use more.

My Stage 2 modification has ensured that my DPF will now last forever, growing cobwebs.

Nobody can answer the OP's question, however, not even Mark Malone.

Likely because admitting changes to software that control emissions devices is not the best legal decision. That said, my DPF will also last forever unless I get the opportunity to sell it one day.

I believe the stock stage 2 tune doesn’t modify any emissions system operations, it mainly deals with fueling, and throttle tip in. I don’t think its going to help out the DPF/SCR system compared to phase 1 fix, if anything the higher EGTs the tune is pushing (still with in safety limits) could possibly maybe shorten the system lifespan.

Again my crystal ball has been rather foggy so who really knows.

I have no idea regarding the malone tune unfortunately but thought I would highlight that on my Mercedes c350 cdi with stage 1 tune and dpf still in place the car runs a regeneration cycle much more, I assume that this is just because of the extra volume of particles it's now having to deal with post modification. I will be removing it soon.

Remove what - the tune, or the emissions equipment?

the particulate filter, hopefully it would liberate a few hp as well

Just to clarify, he's got an eco tune, we haven't been working with international MBs, just VAG stuff.

It's pretty hard to predict longevity on a system that was updated only a few months ago. I just did before/after testing on a stock EA288, 20 minutes apart on a dynapack. The power is identical as expected, boost and rail pressure were slightly higher, as were EGTs. Within a margin of error but the software shows similar mapping changes. Nothing to write home about, no noticeable changes other than throttle response on post-fix tune.

Trust me. It 'feels' like they messed with the DSG WAY more than they did the engine. "D" is now like an ECO mode, and sport is, well... Sport without the annoying gear drop and hold.

Id bet the biggest changes were DEF dosing (fine by me I get it for like 2 bucks a gallon at the fuel co-op) and DSG map.

Emissions component life is variable depending on how the operator uses the car and other conditions (trip length, climate, etc.). So I think it's nearly impossible to say that a tune will affect component life one way or another. And we also don't know if the replacement of emissions hardware during the warranty period is preventive or needed.

I think it's not worth worrying about. The hardware is getting less expensive. If you choose to keep it in place and want the car tuned, do it.
