Diesel+
The world's first app for BMW and VAG diesel vehicle tuning!
In 2022, everything started with the first BMW diesel tuning app "DITUPA". Following its groundbreaking success, we are now continuing with Diesel+ as a follow-up project and are also launching support for VAG vehicles (Audi, Seat, Skoda, Bentley, Porsche, VW). Tuning has never been so safe and easy!

Simply perfect
I bought the app after using a good acquaintance's software for years. The safety-relevant precautions + the diagnostic tool and the good reviews prompted me to buy and try the app. It's a completely new car; the engine software harmonizes perfectly with the transmission software. There are so many options, and if you want to flash back for whatever reason, you can easily reinstall the original software. The support rounds off the whole package fantastically; there is really nothing to complain about with the app and support.

BMW 5 Series with Stage 1 via Diesel+ – 35,000 km experience, absolutely satisfied I had my BMW 5 Series optimized with Stage 1 via the Diesel+ app about 1½ years ago at 81,000 km – including gearbox optimization. Since then, I've driven over 35,000 km – without any problems whatsoever. The engine runs smoothly, the responsiveness is noticeably improved, and the increased performance is clearly noticeable in everyday driving. The gearbox optimization provides smoother, more intelligent shifting. No errors, no jerking – simply a well-thought-out and reliable setup. Many thanks for this outstanding engineering achievement to Mr. Marcel Meyer – I am still thrilled and can unreservedly recommend this tuning.

Easy to use, great support. No connection issues, the first flash process to unlock takes a little longer, after that everything is very fast...then start and drive off. The engine revs noticeably smoother, very harmonically, and feels like it holds power longer in the upper RPM range. You immediately notice the 70NM more torque, very good holding torque. Gearbox flash also works well. There is nothing to complain about, exactly what I expected. Thanks to the informative content on YouTube, the whole thing feels very safe and familiar. I recommend it to everyone without hesitation.
Do you have questions?
Check out our most frequently asked questions about the Diesel+ app. If you have more specific questions, please feel free to contact us.
What can I do with the app?
The Diesel+ App allows you to tune your vehicle from home. With just a few clicks, you can transfer our performance upgrades to your vehicle and significantly increase its power.
What is a license?
If you want to tune your vehicle with the Diesel+ app, you purchase a license that unlocks your vehicle in the app. A license is always valid for only one vehicle (chassis number) and is linked to you as the user.
How long is my license valid?
Licenses for the Diesel+ App are valid for life, provided the same vehicle (chassis number/VIN) and the same user are used. Nevertheless, we reserve the right to change products at any time without prior notice. This does not create a claim for (partial) reimbursement.
How long does the entire process take?
You can use your license immediately after purchase. However, you will need a compatible adapter to connect your smartphone/tablet to the vehicle. If you have already received one, you can get started right away. The process takes only a few minutes and is extremely easy and safe!
What do I need the adapter for?
The Diesel+ adapter acts as the interface between the smartphone/tablet and the vehicle. It is only used to transfer the changed data from your app to the respective control unit in the vehicle. Afterwards, the adapter must be removed from the OBD port. It is only needed if you actively want to make a change with the app.
Are there risks involved in tuning my vehicle?
The app-based tuning process has been tried and tested for many years and is therefore extremely safe and stable. Therefore, no problems are to be expected. If something does go wrong, it can usually be resolved easily over the phone. So there is no need to fear irreparable damage.
How is the increased performance achieved and why is it even possible?
The increased performance of the vehicle is achieved through modified maps in the engine and transmission control units. Our vehicle engineers test changes to injection quantity, boost pressure and much more over a long period of time to achieve increased performance while adhering to strict limit values.
