E 350 G750 Edition

[Developer]

Good afternoon,

Even though hits a Smart CDi it will have DPF and EGR delete with power tuning! We can get some good gains from the CDi model! Should achieve around the 40BHP extra mark which is not shabby considering its 55 BHP standard!

Regards

Anthony @ GAD

40hp increase on 55hp standard - that's some increase

Good evening,

Yes I think its up there! the A160 CDI has some excellent gains also because it start life with 82 BHP and runs a 2 litre CDI engine so I think we can get 105 BHP extra over the standard management!!!!

Do you mean 105bhp total?

 

[GAD Tuning LTD]

No 105 BHP on top!!!

Quite keen to feel how much difference the DPF removal makes.

Scoob.

Would you say you've felt a significant difference with the power remap you've had?

Or do you think it's not enough on its own?

Yes, fairly significant I'd say, a lot more oomph available sooner and for longer in the rpm range. Also, and more significant in daily driving, the car just seems more responsive and even smoother.

I, like many, want rid of the DPF cos it's just flippin ridiculous & cannot be good for longevity. However, I also wonder how much difference it makes to the drive. I've run cat'ed cars that are remapped vs. decat'ed cars that are remapped and it makes a HUGE difference to low-down response and smoothness. I'd expect a DPF delete to do something similar. More about drivability and response rather than new headling peak figures.

To be fair though, I've not really had the chance to just drive mine as it is that much yet, though I am liking it thus far.

Scoob.

 

[C250CDI]

Just to chime in, I have had my car remapped by GAD (W204 C250cdi) this is the only modification i've had done.

I can confirm that the power and torque increase is instantly noticeable and is significant for sure, the car is much much faster through all gears and right through the rev range too.

 

[Carabosse]

Just wondered whether GAD had made any progress on this?

 

[GAD Tuning LTD]

Good morning,

We have been very busy the last week or so and only got back from Germany yesterday morning. I will hopefully be getting all of the technical specs for the sports DPF shortly as testing is nearing its final stages for testing with great results. It is Lake house tuning and Rebellionautomotive who have spearheaded the R and D on the Sports DPF.

Can we assume from this you have given up on the idea of DPF removal on cars with this particular ECU and are concentrating on the Sports DPF instead?

 

[GAD Tuning LTD]

Rest assured we are still working on the off solution for this vehicle. However if we can offer our customers an alternative then why not put this into development.

Absolutely. I'm sure many of us will be interested to see what alternatives you are able to offer.

Sounds like the Sports DPF may be first off the block; can you confirm it is a purely software solution?

 

[Scoob]

I assume it's still a DPF, but ours would be replaced with a 3rd party higher-flow unit - much like when we've fitted Sports Cats to petrol cars. That's done to ensure emissions still stay fine for MOT day however, whereas the Sports DPF is due to the car needing a DPF to be present for a software reason. I don't know if our existing DPF could be modified in any way? I imagine it's too brittle to be hacked about like that.

So, the car sees it has a DPF so is happy from a software perspective, yet said DPF offers much higher flow due to being less restrictive.

Ideally, for me at least, I'd prefer a full DPF hardware delete solution, though it'd be interesting to try a Sports DPF on a car that can have full DPF removal too for comparison purposes. Back to back tests if you will - though that's a lot of work!

Eagerly awaiting more details from GAD

Scoob.

 

[Carabosse]

My understanding - although it is entirely possible that I misunderstood! - was that the "Sports DPF" is actually a means of getting the DPF to regenerate more often.

I am assuming that is purely a software solution.

Hopefully GAD will clarify.

Really? Wow, I'd not have guess that! Isn't regeneration "bad" though? I.e. car uses 20% more fuel and runs a bit rough during the process. Also, if you regularly do resonable length trips, with equally "reasonable" throttle usage, I thought the DPF regen is in effect seamless, as normal driving takes care of it. It's only those who do less miles / shorter journies / potter everywhere (me!) that get forced regeneration.

I'll be interested to hear the details on this as I'd really assumed a Sports DPF would be just a high-flow version of a normal DPF.

Cheers,

Scoob.

 

[GAD Tuning LTD]

The sports dpf is in fact like a sports cat higher flowing will never block but still have good pressure.

The increased regeneration process was an idea however would as scoob said.... it will increase fuel consumption and would not be the best long term solution for owners as a road going vehicle.


Hope this helps

Sorry for the delay

Kind Regards

Gary

 

[Scoob]

Thanks for the reply Gary, it's now clear!

Scoob.

 

[Carabosse]

My thanks too Gary. Obviously this is more complex than a pure software solution.

It will be interesting to see the pros and cons of DPF removal versus Sports DPF. It will be excellent to have the choice.

For us:

Pros: It works.
Cons: Doubtless quite expensive as we'd be purchasing a sports DPF.

My preference would be full DPF removal, as I've said already, however having this as a viable option is great.

Scoob.

 

[Carabosse]

You're quite right. The Sports DPF could be significantly more expensive.

My one slight concern about DPF removal is future MOTs - not a concern at the moment as my first one will be 2015. If they start measuring particulate emissions won't a car without DPF fail?
