C350cdi remap

[foxy52]

I know the OP mentioned other mappers he may consider but just to show what Celtic offer, and before anyone says the figures are pure myth or exaggerated
the proof is in the eating!

My model does not have the DPF so perhaps that is one reason i feel the power more?

What i liked about Celtic is they have agents all over the country and can even visit your home to carry out the remap from there computer, of course the price will vary.

..Interesting thread this .. So you would rec Celtic as totally reliable and reasonably priced.. I fancy an upgrade in power/performance for my C250 CGI.. do u have a contact number/addr ?? tks foxy52

I have read mixed reviews on Celtic and depends on the agent/franchisee that you use to I guess. In one scenario they had physicaly damaged the ECU and after they had finished they just fitted it back in place. The owner had issues with the vehicle and Celtic did not want to know as it was suspected they most prob knew what they had done. Cut the story short when the customer had taken the vehicle to another tuner all became apparent.

Me personally i wouldnt want someone doing it at my home address. Esp as mine needs to have ecu removed to map. Id like to get it on the rollers to see the gains

Assuming yours is a W204 then the ECU will need to be physicaly removed but easy enough to get to.

My advice to you is choose carefuly who you choose to tune your vehicle and do full reserach first and shop around and do not be influenced just on the price!

Im looking at msl at the moment or GAD. Im swayed more the MSL as they have dyno and they always seem busy.

MSL would be my choice, I have nothing against GAD but the hospitality at MSL is 2nd to none plus they can give you before and after results from dyno. TBH, you will not need a printout to show you the difference on your car because there is a day and night difference!

MSL everytime.

 

[s70rmp]

anybody recommend a Celtic mapper in Manchester area ?

 

[Avnt]

Bit the bullet and booked in with msl [emoji15]

Willl that include before and after Dyno runs?

Be good to see some proof, as well as an owner's opinion..

No they normally want around an extra 50 quid for a dyno run.

Ive booked it with dyno run just so i have on paper what its made. Should make extra 40-55bhp and around 80+nm but each cars different

Please, please, please don't shoot me down for asking these two genuine questions:

1) Why do people buy diesel engined cars and then get them mapped to bring them closer to the power of equivalent petrol engines? Why not buy the smoother, quieter petrol car with it's vastly superior power band width in the first place? Is it just because they're harder to get hold of so this is the nearest the owners can get? Sure, the diesel engine's torque is better for towing a big caravan up a hill, but how often do the majority of us do that?

2) If mapping is as good as everyone claims with no negative effects, why don't the manufacturers do it in the first place so they can sell their cars as "more powerful, faster and/or more economical"? The manufacturers are obsessed with making their cars as fuel efficient as possible, they invest in new materials and spend billions developing engines. If they could get their engines to be more economical without a trade off somewhere else, surely they would. A simple ECU software change would cost just pence, if anything, to implement with every car during production, so why not?

I would of purchased the E55 amg w211 if I could of afford one at the time but I couldn't and love the shape of the w211 so 320CDI sport it was. I was under the impression that manufacturers have to meet various countries emissions thus having a engine acceptable everywhere but the trade off being no where near the optimum performance of said engine so there's where the map comes in. Also is the 350 cdi the same engine as the 320CDI and 280cdi. ? Obviously the 350cdi has more power than the others from factory so it can obviously run higher power with no problems. I my be wrong but that's my thinking of it. Plus the torque my 320cdi has is not far off a amg and mine has not been over mapped as it were as I was told it's well within the engine's safe limits.

1. Economy maybe? For me it's about finding the right mix between economy and performance, the 3.0 V6 Diesel seems to tick both boxes - although a little extra power is always nice.

2. I'm puzzled by the same question, although do agree that they have to meet certain environmental and safety standards etc. We do also see, later in the date a same engine model is released with more power.

Hopefully this answers the questions.

No shooting down needed its only a question.

I have it done to improve how it uses the torque and the fuel. I had my a4 mapped and gained a bit more mpg and a load more torque. It made the car feel how it shoulf have compared to the original map. Made the a4 less laggy

I think its the same basic engine just with a few minor teaks. Im sure its OM646 in both.

With the utmost respect a diesel stock standard C350 CDI engine without a remap would have a petrol C350 for breakfast with its torque and the 0-60mph sprint times are pretty much identical. Now a remapped V6 3L CDI engine that is at stock level producing i.e. 195KW/261bhp/620nm of torque can be tuned to produce 700nm plus from just the stock low rpm of 1600rpm to 3000rpm depending on the tuner . With the petrol equivalent V6 3L engine you cannot simply achieve this level of power/torque output. I am not bothered about fuel economy and it did not come into the equation.
Remapping just like any other modification work is carried out at the owner’s risks.
I actually chose the CLS 350 CDI engine simply due to its power and torque delivery from such low RPM range in comparison to the petrol equivalent V6 3L engine and 0-60mp was identical. Surprisingly, the engine is very smooth and quiet and inside the cabin you cannot even tell it is diesel. After going to a highly reputable Mercedes German tuner the engine is now pumping out 718NM of torque, 0-0MPH is down to 5.2sec with vmax and the extra peak torque is available over a much wider RPM range over the stock engine. A stock CLS 63 AMG without any tuning produces around the same amount of torque as my remap.
My remap is also running within the safe tolerance levels of the vehicle’s capability and remains in the same emission class and actually drives even smoother then when the car left the factory.

Wow, now that's an impressive 0-60, what is quoted as stock?

Which tuner did you use?
