i finally go the reply from Mike over at DMS. Im going to copy paste the email because i dont know how to attach it.

[FONT='Verdana','sans-serif']Hi Mike,[/font]

[FONT='Verdana','sans-serif']I spoke to one of my friends who works at a Mercedes dealership about the ECU upgrade I got and he told me not to take the car to merc for service otherwise the “SDS will automatically restore Mercedes code to the ECU”. I would like to know is this true? And if it is will you be able to upgrade the ECU again with no charge?[/font]

[FONT='Verdana','sans-serif']Regards,[/font]

[FONT='Arial','sans-serif']Hi Mohammed[/font]

[FONT='Arial','sans-serif']Your friend is incorrect. The car will not be automatically upgraded. If however it is at any time within 3 years of us applying the initial upgrade we will reinstall without further charge.[/font]

[FONT='Arial','sans-serif']Kindest regards[/font]

haha,

If you honestly want to know what i think mate then i think you should tell this guy that your friend is not only Mercedes trained but actually worked at AMG on electronics integration i.e Fitting the electronic brains into the cold steel body.

The code will be overwritten your going to have to trust me on this one mate.

I hate people like him who grab themselves a lappy then charge stupid prices for 'upgrades' that do bugger all then make sweeping statements like that without any qualifications to back them up, don't get me wrong i don't mind being proven wrong at all in fact i encourage people who work for me to point out any errors we spot in each others work because it keeps the quality up i just hate how this prat can comment on a issue he knows f**k all about after ripping you off.

I would be very interested to know how this guy feels he is qualified to comment on an issue like this without in depth knowledge of the design of the system and the qualifications to back these statements up.

If i where you i would ask for your money back and then go to a Mercedes dealership and ask to have the stock code verified, your my mate and i have no reason to tell you 'porkies' unlike this clown who has just charged you for something and i can assure you the code will be overwritten.

I know the car feels different but i just want to remind you this will void your warranty and if i point out that the ECU for the engine alone is worth over £1.5k you might seriously consider if this is a wise idea.

First of all Mjawa55 welcome. If you want a better feel I would suggest from what little I've gained from this forum to get a sprintbooster. According to Dan ( and correct me if I'm wrong), at least it doesn't hurt the car and the car seems to feel faster.

Anyway, safe driving!

I'm not a big fan of either ECU mods or the Sprintbooster to be honest because they play with very complicated electrical systems that have taken years to develop and have absorbed millions of dollars in doing so.

But if i had to pick between a Sprintbooster that sits on the potentiometer lines or a mod to the cars OS i would vote for the Sprintbooster without even thinking about it.

When i think of downsides the first one with the Sprintbooster is an increase in difficulty parking but when i think of an ECU 'tune' i think engine damage so you can see why i would pick the Sprintbooster.

I'm sorry if my other post sounded like a rant it was not meant like that at all i just hate people who will basically steal money from others without providing any service in return and then to go and provide a response like they have when MJawa 55 e-mailed them is really taking the piss.

Dan thank you for the reply, ill make sure that my cousin goes MB before the xmas holiday. as i said before Dan i trust you and you knowledge of cars over any fool that just wants money. smoothbenz i had a sprint-booster for a while but then i got used to the quick response and it became boring so i removed it.

Your welcome mate,

If you go back to DMS first to have them remove the map because they are more likely to refund your money doing that rather than going to Merc first, once the new map has been removed then go to Merc who will make sure the car is upto date.

dan, actually what most of them "ecu tuners" do is play with fire when "tuning" n/a engines- they lean out the a/f mix a bit and try to add more timing at mid and high rpms- on some cars this will work when the manufacturer has left some "safety zone" and the car runs a little rich from the factory. the blown 55 and turboed 65s are a smidgen rich for safety, so more boost along with some lean-out will yield significantly more power- yes. god help you if you put a bad tank of gas though- the ecu will retard everything so far back that the car will be slower than stock with the same gas quality.

however, i have a wide-band that i have connected to an slk55 and that particular car did run at 13:1 at wot. i would not under no circumstances even think of leaning-out a 13:1 at wot setup.

so i will be somewhat blunt- i do not believe that anybody can get 40 more hp out of the n/a 55 engine reliably. there is just not enough to play with this engine when stock.

btw, a faster throttle-by-wire can leave the impression of more hp - so i am suspicious that the hp claim is bogus, but the step motor driving the throttle body(ies) has been sped up.

and yes - dms is a very reputable vendor, but sometimes you have to question even the best...

Mate they don't really have a safety zone even on the S/C's its thermal management, same reason they pump in fuel on the over-run is not to be played with.

That being said i agree with you and as i have said before blown cars do have room for improvement but nothing comes for free so you pay for it in overall life.

Now i know we are basically saying the same thing i.e We doubt this result but you wont gain anything by playing with the map on the SLK55 its just not possible, no padding to remove, no room to play, nothing.

We really are talking 0% of nothing to play with here leaning it off wont help you, you can't play with the speed of the flapper or anything since thats not a software variable setting (old tech ECU compared with the newer engines).

Again i know we are both basically saying the same here but i just want to make it clear here, i have been working at Mercedes from as soon as i left school I've spent over a year at AMG and been working with high performance MB's and other German brands since then, not once have i ever been given proof of any enhancement from people playing with N/A engine ECU's without hardware modifications to back it up, i have seen a good many cooked ECU's mind you.

For the price of an ECU mod you can buy sport cats and a X pipe and the former in particular will produce a noticable difference in power output.

yes. we are saying the same thing and i absolutely agree with you. i dont know the n/a 55 engine but i do know its a/f (unless my car was atypical) and there does not seem to be room for improvement.

intake, cams, headers, exhaust- there is something to be had there- i am sure there some nice gains when uncorking amg packaging, pollution and noise restrictions.
