Frequently Asked Questions
Is ECU tuning safe for my car?
Yes — when done professionally. At Euro Bimmer, we tune within the safe parameters of your engine and drivetrain. We never “push limits” just for numbers. Our focus is on reliable, long-term gains that enhance performance without harming the vehicle.
Will tuning void my warranty?
It depends on your warranty provider. Some manufacturers or dealers may flag tuned ECUs, especially if the changes directly relate to a warranty claim. That said, we offer OEM+ tuning options designed to minimize detectability and risk. Ask us about your specific vehicle and we’ll guide you.
Can I go back to stock if needed?
Yes. We always keep a backup of your original ECU/TCU software, so we can return your car to stock settings anytime — whether for warranty, emissions testing, or resale purposes.
What if I already have a tune from another shop?
No problem. We can inspect your current tune, scan the car for compatibility, and either optimize it or safely reflash it with our custom software. We’ll walk you through the best path forward.
Do you offer dyno tuning?
Yes — we offer custom dyno tuning by appointment for advanced builds. If you’re planning a full Stage 2 or Stage 3 upgrade with turbo, fueling, or internal mods, we can set up dyno calibration with one of our tuning partners.
Do I need other upgrades for tuning?
For Stage 1, no — you can usually tune on a stock vehicle. For Stage 2+, you’ll likely need supporting upgrades like a downpipe, intake, intercooler, or upgraded turbo. We’ll help you build a safe and balanced upgrade path.
What brands and models do you tune?
We specialize in tuning premium European vehicles such as BMW, Mercedes, Porsche, Audi, Land Rover, etc. — where we have the deepest experience, tools, and platform knowledge. This includes performance variants like BMW M, AMG, RS/S models, and more.
However, we also offer tuning services for other brands, including domestic and Asian vehicles, depending on compatibility and platform support. If you’re unsure whether we can tune your vehicle, just contact us — we’ll evaluate your setup and let you know the best options.
How long does tuning take?
Stage 1 tuning: ~1–2 hours
Stage 2+ upgrades: ~4–6 hours
Custom dyno tuning: full day or more (by appointment)
We’ll always give you an estimate based on your specific car and package.
