so i wanna know what kind of hardware do i want and software  to use best for tuning  bmw , Mercedes,  vag group
plus qhat should i learn first before starting  to do anything myself i have the basics knowledge  of cars but what steps or courses should i look for?

I would start with learning how to proof read. After that you may want to look around the forum before asking to be spoonfed, it's not received well around here.

i knwo what u mean but some people told me to learn winols first some said just buy a subscription from a company and u will learn with time and saddly nowhere close to me want to take me as a trainee cuz they just enjoy being alone in my local market some people aslo said for me that an mpps is enough some said kess some said ktag and i dont know where to satrt bec the is too many advices and i dont which is better 

Are you looking to actually tune or just flash files?  Do you have a dyno? 

i dont have a dyno but there a road close to me long with min. turns and no houses near it nor traffic so i guess it would serve as a good test ground
plus i dont wanna to be like an idiot just flashing files i want to know how to make a custom tune from zero ( i know normally i will not do this but i wanna have knowledge that will make more like a pro) no matter how long it will takes or hard and btw i am still a college student in gas and petrochemical displine so i am a bit short in time and money but i will try my best to reach my goal
sry if i talked too much <3

I would say as a noob to direct yourself towards the calculators you want set so as not to confuse your head. knowing how an engine works with all its sensors, knowing how to disassemble and reassemble an engine is one thing...knowing how an ECU works is another matter. I already advise you to read a lot on this forum, learn to become familiar with the names of the maps...and yes why not play on ols with files to understand the base. mpps kess.... are just tools, there are many of them... depending on the communication protocols....

thanks buddy ❤️

If you're just a student, then pick a different career path.
This industry is in it's twilight years.

By the time you get anywhere, most new cars sold will be EV's.
I'd say there's 10-15 years left to go, after which it will be a handful of people fighting over scraps.

Fine for those of us, who have been doing this for over a decade, as we will be retiring, but now is not really the time to get into it professionally.
Still completely fine to do as a hobby though.

Depends on what country he lives in. EVs might outnumber ICE cars but in many countries (including mine, Greece) the charging infrastructure is simply not there. EVs are not suitable for long trips.

@prj I also need help regarding WinOLS, as I cannot seem to make it work for my ECUs stock map (Marelli IAW5NF.T9, software K34A).

I installed EuropeGas LPG last February and now I want to further tune it regarding timing advance as right now it seems that it has 5% less horsepower at full throttle over 5000 RPM.

On closed loop operation the LPG tuning is perfect and it matches the petrol values (lambda = 1.00 - 1.05).

I don't think my ECU supports map switching. Any ideas?

i am not doing it as career  just more of something  i like so i wanna be good at it and help others in my country who wanna start in that plus the place i am from (egypt) EVs are really rare here so i guess we can more than 15 years to be completely  replaced in fact we have old cars still used as a daily here like e36 and e30 old fiat cars too

Read this, and try to fully understand what is going on.

When it comes to getting into car tuning, it's crucial to take a methodical approach. Start by selecting a specific car model or type to focus on. Begin by gathering comprehensive information about the engine control unit (ECU) used in that car. Once you have a solid understanding of how the ECU functions and have a reliable method for logging, flashing, and editing it, you can consider exploring other platforms.

My journey into tuning started with a Saab NG 900SE, and I made my fair share of mistakes, even blowing up the engine a few times due to my initial lack of knowledge. It was only after investing hundreds of hours in research and learning that I could create a tune capable of keeping the engine together. However, I still encountered drivability issues that needed addressing. It took me two years to gain enough experience to create a reasonably tuned setup for DSM 450cc injectors and a hy35 turbo. Another year and a half was spent fine-tuning the setup.

All of this happened 15 years ago, and my main message is that car tuning is not something you can learn overnight. Focus on mastering the basics and be prepared to dedicate all your free time to scouring the internet, even delving into decade-old forum threads. Information is more accessible than ever, but you'll still need to put in the effort. Don't hesitate to take notes; my desk is a testament to that! Retaining all this information is a challenge, but knowing where to reference it is essential. I hope this insight adds a layer of clarity to your goals. Best of luck on your tuning journey!

thanks man for the advice i will work with it but i am now working with a 2 books by greg banish since they cover most of basics i guess then gonna start learing winols to learn how more qbout the ecu and how changing a parameter affects the car then i will go and start by focusing on one model
