I've got the POWER! C350CDI

[ace571]

Well, that's made my mind up then - it's not exactly a slouch out of the box!

 

[NinjaMatt1]

I am sure that we can put minds at rest with regards to the Gearbox , Rolling roads can measure torque too fellas! and this is a full remap!!! adjusting power to get the best fully commissioned power.

Prices are private as not to end up in a row with other tuners that do a partial job and claim the same results.

Warranty will be fine, as a fully covert route will be taken that takes a little longer, this is not a cheap job...just what seems the best one I can find in the uk wanting not to effect the warranty.

For other models just give them a bell and ask the question if you like.

5 areas are tested during the remapp, also measuring Exhaust Gas Temp, so no melted pistons.

The lag is the Torque converter, which is worse in E or C mode rather than Sport and guess what it is software driven so hey presto!

I just want the best for fellow members so general interest only please...I have saved the direct emails from my Yahoo box.....if you are interested drop me a mail there and we will give you a price on the different cars as we go. Having just checked my email I might just have a chat due to the number of direct email responses and just use a special code to get the rate, way past 5 cars as of 11.00hrs today.

Thanks for all the comments....this is the route I am taking and feel free to join me if you want some more zing in your sang!

Later Ninja Matt

Just renaming the file to the same as the original doesn't stop the ECU recording a software upload.

Just looking at the smoke output and the feel of the car says whether an ECU has been mapped.

Yep, No renaming a file and if you are returning for warranty work it can be changed back to original state if you ask.......Ta

The warranty is not going to be affected if something either not directly related to the power increase ( say windscreen wipers or wheel bearing) and quite cheap to fix fails. No-one will bother to look for a remap.

However, if something expensive like a gearbox or engine failure happens then the manufacturer might well want to investigate. If they want to look they will be able to find out if the map is different.

They will look at the update information that will be recorded, they might look at at a checksum value which will indicate changes; now you might say these can be 'spoofed' and you might be correct but at the end of the day they know exactly what the code and data should look and they can quite easily compare what it should look like with what it actually looks like.

Having said that I'm not against remaps and the like; it would just be better if organisations offering the service were more up front about the potential issues as well as the advantages.

Fair Comment....on the gearbox questions - The gearbox can take it no problem, the 7 speed box is also used in the ML420/ 450 CDI with not many changes, our upgrade is way under the torque threshold.

Will advise if the reference code route is the better way with demand in mind, cheers fellas!

Do you work for DMS fella?

No I run 3 Martial Arts Schools, hence the name....

iirc, the ECU still records the software upload.

Surely asking the manufacturer to support warranty claims when the car has been modified is wrong, isn't it?

Yes it's wrong and I wouldn't bet against the manufacturer being able to detect that an upgrade has been performed even if the original map is re-installed. .

Given that failure, if and when it occurs, could well immobilize the car it could be tricky to get the original map back in place before the dealer get to look at it.

Remapping, professionally done taking into account engine and transmission specification and limitations and openly explaining the position wrt warranty and insurance is fine.

From what I've seen most organisations offering to remap cars just don't do this.

If anyone wants to remap their car that's fine but try to find somewhere that really knows what it's doing and is completely open about both benefits and drawbacks.

Suspect most organisations offering remaps buy their maps from the limited number of places that have the ability to do the work to produce a new map and just install them.

Also suspect that custom maps are merely a remap in which one or two parameters have been left for the fitter to tinker with.


Try asking what gearbox your vehicle has and what the max continuous torque rating is for that gearbox. Some places might know. I'm willing to bet most don't.

yes, for claims relating to the drive train but if the steering goes pop or the brakes don't work or the car corrodes then its not really the fault of the map.

In cases does the mapping company not provide a warranty or cover.

The short answer is no. Brabus do but it's limited to 60k miles.

I'd be interested to see details of any warranty offered by a remapping outfit.

 

[timskemp]

Don't forget that you are only putting extra strain on the engine when using it at full power, it's probably negligible in normal use. My s60 was mapped for more power and I never had any problems in 139k miles with it, not even a clutch (it was a manual)

True, except the issue appears to be more about the torque and it's effects on the gearbox. In stock form the current C350 CDI produces 620nm at 1600rpm.

A remap will take this to close to 700nm, if not over it, and at similar rpm I guess the effects on the transmission will be pretty significant?

*technically* the mfr can deny warranty if you've changed the tyre spec from those which arrived from the factory, so, even if you've shredded a set, and the car will only do 100mph and had 140mph rated tyres on it and you choose ones rated to 110mph - you are screwed......*technically*

D.

 

[jumperjohn]

I filled with Shell V power today and it's quite a noticeable smoother delivery. Anyway, I'm not bothering with a remap, I mean I already have 388 hp and when would I ever use what I have. I think some on here need to ask the same of their current cars too.

!

The torque threshold for the box is 700nm. The DMS upgrade takes the 350cdi to 720. another poster indicated problems if you just go slightly over the limit. Note - the Brabus only takes it to 690 - for a reason no-doubt.

I remember Tiggers mapped e320 Cdi spitting the diff out of the back of the car...Oh, how he laughed...

Out of interest, what does the 'old' 5 speed gearbox go to torque-wise?
