Has anyone on here fitted a tuning Box on a petrol SLK R172 200 or 250, if so what are your thoughts and comments, is a tuning box safe or not?.
I have one on my car and it certainly appears much quicker, it is a Bluespark box with stated gain from 181 BHP to 211 BHP and it feels like it.
The box links to two sensors, the Map sensor and the Boost sensor, can this box damage your engine, probably not, because it appears modern direct fuel injection turbo engines have very sensitive knock sensors and closed loop wide band Lambda sensors to protect the engine and controll emissions if the car strays outside of the manufactures limits set within the mapping and the many tables the EMU accesses. If a sensor fails or the fueling goes outside of these set parameters the EMU will throw a CEL and probably put car in limp mode. Early cars without these protection systems probably were damaged as it appears an uncontrollable lean mixture on petrol fuelled cars can destroy the engine in seconds.
Hi
I have done it and had it about 3 month. Made a big difference :wink:>. As a default it went from 184hp into about 211 hp. Then I can manualy increase about 5 percent * 3. It allows me to extract about 240 hp as a maximum. The box is from a reputable German company and they give guarantees in Norway in case of any engine damage. The company that sells this in Norway has been around for more than 10 years and I have never heard that anyone has suffered damage to the engine / gearbox due to the tuning. The box is programmed to optimize specific engine / gearbox. Fuel consumption is equal at the same driving as before tuning, but of course if one squeezes out maximum performance then it will also consume more :smile:
I wish I could buy one without having problem with my car insurance...
I bought a chiptuning box that connect to the ODB2 but I really have the impression that it does nothing...
In Norway you are alowed with 15% deviation. The one i linked is default inside that range. It is pitty if it not work, but the German product i linked, and have, realy work. When we buy it we have one month try and if we are not satisfied we can have our money back. How can they give this kind of return promise. Because it work
People do not want to return it. 0-100 km/hr get about 1 sec better, but even better you realy feel it when you want to drive past cars. Even The sound from my AMG exhaust package change the soundscape with the tuning box. The sound get greater because, as I understand, the turbo get a higher pressure because of the increased performance
It's a shame you wasted money on that one. The box I have works, as you also mention. In addition, it can be placed out of sight. It cannot be read by diagnostic testing. nor can it be changed by resetting in connection with service because it is bypassed.
If you buy a bluespark box for about £160 you have a 28 days money back warranty, win win here, if you are the first purchaser and change cars you can have the box reprogrammed for the new car at a cost of £60 + postage, have now sold SLK but still have a 180 C-Class Coupe, box now fitted to that car, certainly makes a difference, gain is from 156bhp to around 200 bhp.
I bought a Racechip box as they seem to have a good rep and it appeared to be a simple plug n play install. The packaging looked very professional and slick but the instruction booklet only had a generic description of how to install it rather than the car specific as they advertised. Two sensor sockets had to be located, the turbo boost and MAP. However, after trawling through loads of YouTube videos I got the impression, rather than plug n play as Racechip described, the unit was a lot more trouble to install than they had described. I finally found that the MAP sensor is below the airbox and on my 2012 R172 it's quite a palaver to remove as there are numerous other leads tie wrapped to the bottom part of the airbox. I therefore decided to return the unit to Germany and I'm now waiting for full refund.
After more trawling I've decided to have my ECU remapped by Celtic tuning in Cornwall, which isn't far from where I live. The general belief is is that ECU mapping is the better way to go rather than simply boosting the turbo like the Racechip unit. Celtic tuning tell me I should gain around 50 bhp.
I'll report back later in September once it's been done.
Just added a DTE Pedal box and it’s fantastic.
I hardly touch the accelerator and my wheels spin which is a massive change from the crappy curve I had before.
Having an engine remap on Thursday.
Remapking has £100 off until end of this month and they come to you anywhere in the country as far as I know and their reviews are fantastic.
It will be like having a new car once my Fox exhaust goes on this weekend
I’ll post pics after all is fitted
The M271 blueefficiency 1.8ltr 156bhp engines CPU`s are locked, well they were last time I enquired. As far as I am aware this engine cannot be remapped through the OBD2 port, bench remapping only. Personally I prefer the Tuning Box, it does not mess with the mapping, can only work within the parameters of the original factory tune, so is safe. It is also reversible within minutes. The box on my C-Class works fine with no EML`s.
@Migsy999, looks like you are adding a few upgrades to yours. That DTE pedal boost is certainly a good one. I have the Piecha version in mine and it makes a whole lot of difference to the "feel" of the car. With the Fox exhaust, you will transform it even more... All good stuff... Looking forward to seeing it all put together.
Today had the remap.
Fitted HID lights.
Vinyl wrapping the centre console.
New wheels a couple of days ago.
Piecha exhaust and Diffuser coming tomorrow.
Wald kit on way from China.
Subwoofer and Pioneer stereo upgrade Saturday.
^^^Methinks you should create a new thread to better document all of the upgrades you are making, that way it is easy to recall what, when, and for posterity. With time past, and you look back, you will be amazed to see where you started to where you ended... altho' truth be told, modding never ends... its a disease...>:grin:

ive got one dte earlier in my 2020 ford everest 2.0d biturbo
dte claims that +24 bhp from 213 to 237
0-100 is 9.5 sec , as std from 11 sec
that why i buy another dte for slk
but the result is quite disappoint
Then I got it cheaper in Norway. Got some discount because I am a member of a Norwegian Mercedes club. Paid $ 600 include installation, plus I can have it reprogrammed and customized for another car in the future for free if I want. It is very important that the tuning you have received is adapted to your engine precisely, if not it can harm your engine, and at same time you do not achieve what you want. Hope you have bought it from serious DTE dealer.
I always recommend to do a correct and clean ECU ReMapping with YOUR DEFAULT ENGINE VALUES to tune engines. Due to manufacturing tolerances and the driving style in the first 1.000 - 5.000K`s, the engine is never the same! That means, that same model-year, engine and gearbox will always will have different default learned and saved values in the engine ECU. This tolerances also can be noticed in the fuel consumption, that identical setups on paper will always have different consumptions at all.
There are a lot of ECU Mappers around the globe, who do ECU Mapping very cheap. In most of the cases they are buying Mapping files for one engine and gear type and flashing it over if model-year and engine + gear type are the same. This is also NOT RECOMMENDED! A good tuner or workshop will always will read out your ECU Data and will optimize YOUR Dataset including all relevant paramters for correct cooling, timing, rail pressure, fuel injection etc.
In most cases this kind of "cheat-Boxes" or PadleBoxes or USB-Configurable stuff are just hanging between AirFlow, CR or Kompressor and are tweaking given parameters. Sure with more pressure of the Kompressor, your engine will run great but the questin is HOW LONG! And How funny is it, that peope are allowed to play around with parameters via smartphone-app or via USB and PC without any clue what they are doing. More pressure, more fuel and everything on maximum will give more Fun - for sure maybe for the next 999K`s
The M271EVO engine with 184hp is able to remap over the ECU to have:
default 184hp with 270Nm => 240hp with 400Nm => in Europe about 350 - 699 bugs
Some are also going on 250hp but that is the MAX what the engine gives without any hardware changes. But if this is long lasting is in the stars
And it is no secret, that this M271EVO Engine ECU is not that easy to Flash and ReMap so this can be more expensive regarding other ECU Mappings.
