Just wondering what you are using to download the bin and if you are using WinOls or something else.

 

This is also something I would be interested in knowing. What software will allow you to tune your own car, and what software are you using to datalog with?

 

No, I chip tuned my car from Tuningfileshop. Here is an insight on tuning, hope it will help you:
With the introduction of Electronic engine management, chip tuning has become widely popular. Now, chip tuning has a greater scope to improve engine performance.

What is the need for tuning?
Tuning gives our vehicle extra performance with a better fuel economy. This is the reason that people chip tune their cars. Car tuning aims to improve engine efficiency by around 10 - 15%.
Important things to remember before tune
There is a number of cheap tuning software available online. But before tuning, there is a need to consider some below mentioned important points:
Before tuning, check your car history. Check its tires & suspension system. If you have any type of problem with the engine, then please repair those problems before starting the tuning process.

Researching on tuningfiles tool would be very beneficial for you.

Want to enhance your car performance? If yes, then go with chip tuning without any hesitation.

 

Same question here. How to get the ECU read/write file? What hardware tools do we need?! Thanks

 

Hi there! I had some of these questions too. I went to OE Tuning's website and ordered a tune for my 14 e550 coupe yesterday. I spoke with a Jerry there, here was very helpful and explained the process to me (hopefully I remembered it correctly). Here's what's involved:
1. Find your make, model, etc, and it'll show if they have a tune.
2. Purchase the tune and also the OBD2 Flashloader/MyGenius ($250), this is the hardware you plug into your cars port (near steering column to the left).
3. Once you get the package from OE Tuning, you use the MyGenius device to plug into the car and it will "read" your ECU. Then you're able to download that file to a windows pc and email to OE Tuning.
4. OE Tuning then writes a tune for your car and emails it to you.
5. Download the tune they email you to your MyGenius, then plug in the MyGenius and "write" the tune to your car.
Some side notes: You'll need to have a battery charger hooked up to your vehicle when reading and writing as it does drain the battery and you don't want the battery to go dead while this process is taking place. Also, you can switch between the oem tune and oe tune. Also, use STAY2020 to save 20% off from them right now.

I hope this helps (somewhat). Sorry for the choppy info. Hoping to get mine next week!

 

Yes I guess everyone is aware of tuning specialists or reputable tuning companies who can help with the tune. I think this thread is more about enthusiastic approach on how to tune the car by yourself. I have exhausted all sources and it looks like there is no too much of choice. Essentially there is no similar to SCT or Diablosport handhelds programmers which would allow you to change the ECU settings on the go. Needless to mention the TCU on Mercedes: it was totally hidden gem until recent time. Now Eurocharged can tune the TCU if you can afford. I miss my Camaro more and more. That car was much easier (and cheaper) to deal with.

 

I just recently gone down this rabbit hole. I have a s600 w220 variant. My ecu is me2.7.1. I had to pull the ecu and read it with ktag clone. I can write with ktag clone or kess v2 clone through obd2. The ksuite software for ktag and kess v2 is different. V2.25 for ktag and v2.70 for kess v2. Word of advice, don't solder to your ecu! Get the mini grabber probes off Amazon and save yourself an ecu. The legs on my boot pin snapped off, ecu go bye bye 😭 good thing I backed up my ecu before I broke it. I was able to buy another ecu off ebay and flashed it with my backup. This is as far as I've gotten with programming. Best of luck to you. Learn lots. Maybe I'll be in need of your service one day

You can buy a bidirectional scan tool from autel. Aparently the more money you pay you get access to higher programming privileges. I should have bought the one for 4k. That badboy will even reprogram the Vin number

 

I've been tuning cars for 13 years, in fact, slowing down now with the EPA becoming stronger and stronger. Making any modifications to any emissions equipment on a vehicle is illegal so I've never tuned as a business, never charged anyone for a tune. I have tuned or built and tuned numerous platforms, but not Mercedes. I use an invasive SW from HP Tuners. HPT does cover some MB models, but I don't follow which ones. For my AMG GT, I stay stock.

Some words on this subject -
SW programs like HPT and EF Live are NOT for beginners. There is no guidance past blogs once you're into data tables. You MUST know what you're doing or the damage you can do is unlimited.

Another important point, data files in the EMS are, essentially, the manufacturers "intellectual property". Manufacturers, over the years, have taken different measures to protect this property (especially with car warranties). No one is allowed access to these data files, including dealer techs. SW mods are always done by factory engineers. Field techs might install a SW update, using factory tools, but they do not see past the rev file. So, products such as HPT and EFL are really hack programs.

Some manufacturers are rolling out hack proof architecture now. One of the recent famous ones is GMs B Architecture used with their E99 EMS that uses a firewall with a random rolling access code. The hack companies have yet to get in these ECUs.

For the platforms in which I tune (have tuned), each is different in its approach and it took years to learn ins/outs of how these systems are designed and I am a Mechanical Engineer.

Although popular, I'm not that big a fan of canned tunes, plugins or ECU swaps. In my experience, even identical engines in similar cars fine tune differently. I've only ever created a "generic" tune as a starting point, but often do not see the same exact settings of everything on two different cars with the same architecture. Companies that provide these products are big business. They use a mule to set up data tables then copy those files over to customers. This is just OK, but not a fine tune. It's not a condemnation either. Most canned tunes are simple "bumps" in simpler parameters that give results, but would not fit into the "finely tuned" category, at least in my eyes.

The platform I use, HPT contains both an editor and a great datalogger. With these tools I've built and tuned some bigger performance engines including NA platforms to Boosted ones. With big moves like these, everything is impacted - Injector size, spark plug temps, fueling, timing, Power enrichment circuits, idle circuits, torque settings, and more.

 

Chip tuning. Increases engine power. It is performed only in specialized workshops. Here it is important not to "go too far", in fact excessive power negatively influences the gearbox, suspension and other units.

 

Wow! How does it change the VIN plates?

 

it can't change the Vin plates. It can rewrite the Vin number on any ecu or modules. Lets say you need to change your ignition switch and you buy a used one off ebay but the Vin number on the unit doesn't match your car. With the 4k autel you can change the Vin number on the part so it becomes compatible with your car.
