B&C consulting tunes??? Somebody knows them?

[Felo]

Hello fellas!

I've been reading a lot of your threads about piggybacks and tunes like apr, revo, unitronic, eurodyne and so, and I can say that I've learnt a lot with you all, but today I found a local dealership that offers this tunes called by B&C consulting that offers the average increase for stage 1 and 2 like the common tuners, but the big difference is like at 30% of the price.

Do you have some information or experience about these tunes? I don't wanna pay more because I tried to save some money because some tune destroy my engine.

This is the website and results

Have a great weekend and stay safe!

I’ve seen the file they offer, with that said I don’t believe it’s something that will blow your engine up, but it’s also not going to make those quoted figures

Hello mate, my concern about them is that there's no one review, thread about their maps, certainly because their local dealers sell their tunes with a different name you know, anyway I think that it's better to go straight with apr, revo, unitronic, giac or eurodyne just because there's a lot of people showing how those tunes are

Theres a good chance that BC provided your big name tuner with example files they needed to start tuning on mant different platforms.

[irish07]

As above poster mentioned, BC most likely provides a starter tune for your local tuner to edit(file on WinOLS database). BC also has the option to do a file service, so your local shop reads your car, sends the file to them, BC edits and returns the file within Belgium working hours (CET).

BC is a fairly known company in the tuning industry, know for there bFlash tool and sourcing damos/mappacks for tuners(stuff tuners use to define a file, but BC charges 10x more same damos).

Just my option, but there’s lots of other file service companies that can provide a better overall file for this platform.

Exactly that was said my local tuner, firts to read my map and then send it back to b&c, and then they would send back the stage1 map, but my big concern is to know if is safe or not, considering that the price is easily 40% of a apr stage 1 for example.

Look for a local tuner that can modify it as you wish. I don't think you'll be happy with the B&C file. They prefer universal solutions, which means you won't get the maximum. The Simos 8 and its torque model is already well known to all tuners. If you find a way to read and save the batch I can easily make you stage1 or 2. I have successfully modified the engine and gearbox software in my S4 myself.

I will see if I go with eurodyne because you can get stage 1 and 2 for the same price.

Antother question, do you know if is some way (without going to the dyno) to know if I'm stock or with some tune, because today I raced a friend of mine with a s4 b8 stock and between him and I there was 3 to 4 cars of difference, with mine ahead. I'm curious just to make sure if I'm stock or not about the map engine.

To see if your car is after tuning or not, there are several ways. Login your car with e.g. vcds or any other interface that is able to read the intake manifold pressure. Originally it will be 1.7bar, stage1 1.9-2.0bar, stage2 SP 2.1-2.2 bar...etc. You can also measure acceleration times in the speed range 100-200 e.g. Originally about 14 seconds. Stage1 - 12s. Stage2 - 10s. You can use your smartfone with perfexpert app (10$) and mesure Hp and Nm.

I'll check with torque pro the intake manifold pressure to find out and come with the update 🤔 thanks mate

Zbichu I've just used tje torque app and measured the boost and also the afr what do you think about it this:

Peak Boost: 14.3 psi
Lowest afr: 9.7
The highest afr was after wot at high speed

Here is a short video of the run

https://youtu.be/uhxiKKVMY7M

[Zbichu]

Peak boost 14,3 psi 0,98bar shows you are stage1 (dont belive torque pro app PID's). Peak measured power 281whp shows you are stock. Measure 0-100, 100-200 times with this app.

I've already tried the 100-200 kph firts time was 12. 2 sec, and then 13.6, I'll try again to check if is closer to the 12 or 13 sec

Funny how I was just reading Simos 8.5 docs (funktionsrahmen) trying to figure out how the load is derived from the driver's input and other factors. I haven't seen anything regarding selftuning of 3.0tfsi so far, unlike the n54 or n55 engines where there are a few threads on e90post.
I'd be curious to learn from you how you tuned your 3.0tfsi, I'm also looking to selftune my car for self-education purposes.

[Zbichu]

No problem. Let's start with this. Can you read and write the simos 8.5 driver? If you have already read the batch, can you find the right maps? If you can do that, it means you have a damos to simos 8.5 description file or similar. Now all you have to do, is to get the right model.
I'm going to try to explain this to the most ordinary stage 1.
It all starts with pressing the gas pedal :) There are some maps in the controller that correspond to the percentage of the pedal inclination. There are many of them and they are called differently (driver wish for example). They have monitoring tables too…, but we will skip them this time, because there will be no changes.
Percentages from these maps, i.e. how hard the accelerator pedal is pressed and on which gear they are implemented into the torque maps. This maps are called ip_tq_pow_max_at[0])[1]…etc In Simos 8.5 funktionsrahmen. The highest value in these maps is 459Nm AT 3000 rpms, which is more or less the same as 450Nm assumed by the manufacturer. Thus, 100% of the gas pedal press is equivalent to approximately 450 Nm between 2000 and 5000 rpm. At 6000 rpms the setpoint is 400 Nm, which after converting to mechanical horses gives us about 333 hp declared by the manufacturer …
I'm gonna stop this story here and wait for you to tell me how you look at it. The Simos 8.5 driver documentation contains 13000 pages. Most people who read it, do so to boost power in 3.0 tfsi. I'm convinced that more than 95% of the people who read this documentation still can't increase the power in these engines. No offense, but you're an example. The worst thing is that such information can be given in a few sentences and then you don't have to flip through 13000 pages. Show some of your own invention.
Will be continued...?

Oh, man. The result is between stage 1 and the original. Put in this application clocks with afr, intake mainfold pressure, engine speed, horsepower. Record a video of how you're driving the car from say 2000 rpm to end of 6400-6900(I don't know if you have a B8 or B8.5) in 3rd gear. 4 would be better, but it's too fast.

I'll do it as you mention trying to find a road with almost no inclination to remove this factor from the equation

I don't have damos files for simos 8.4 yet, the only thing I got is FR for 8.5.
I haven't read the calibration data from my ecu yet. I was planning to do it using either elm327 or, to speed the development of the script, using D-CAN cable I got. As far as I understand, simos8.4 uses UDS protocol and there are many libs which implement it. Not sure which of those implement requestDownload or whichever that called routine. Speaking of download and upload to the ECU (or DME which is how some like to call it), it should require authorization. How do I respond to a "seed" sent by simos8.4, what's the algorithm to convert that seed to a key I need to send back? Lastly, my understanding is that it will send encrypted payload, but the encryption is very primitive (xor). Is this correct?
My understanding of reading and writing of the data from the ecu is somewhat limited right now. So far, I've only made some pretty basic iOS app which I limited to reading measuring block data, reading and clearing DTCs so it won't accidentally brick a control module when doing coding or running some adaptations. While I decided not to do UDS (because UDS measuring data is useless without ASAM/ODX datasets), I did KWP2000 over TP2.0, which is still used by many b8 modules except for the engine and trans. Although UDS would be much easier to implement compared to KWP2000 over the TP2.0 (the main problem being TP2.0).
Anyway, I'm going to see what can read UDS ecus using dcan cables, if I can't find anything, will need to come up with some Python script to do that.

I see you're doing a lot of work on this. But maybe it's not worth breaking down an open door like they say in my country. Just buy a ready-made tool. Not as expensive as CMD, MagPro X17 or AT tuner. There's something like the $18 PCMflash and the Simos 8.* reading module costs $170. https://tuning.energy/en/pcmflash-57-simos-8-pcr21/

What fun would that be? I made my app some time ago without ever thinking I'll get an S4 to goof with my mk5 Jetta Sportwagen, so not doing too much work now.
Was able to locate some semblance of damos files for simos8.4 and found a table you were talking about.

If your doing this for hobby it’s one thing, but to not spend $200 on a tool that can already datalog and flash is kind of counter productive. All that time could be well spent researching the mapping to better performance and drivability versus spending weeks figuring out how to get simos8.4 to ID/Read/Write/correct checksum..etc

Btw, if your going to be using damos files and need the odd help with files, you’ll want to have a certified version of WinOLS..otherwise most of the damos or help from ppl will be done/performed on newer versions than the hacked WinOLS version(older versions can not open newer version edited files)

If you don’t have WinOLS and only current plans are to edit your S4..might be more wise to use interface tuning, like something for HPT. You’ll be able to get a overall good Stg1 with HPT maps..dual pulley will require WinOLS and knowledge on how to use.
