FAQ
Frequently asked questions
Everything you need to know about ECU chiptuning, the process, compatibility and our delivery. Still have questions? Contact us.
What is ECU chiptuning?
ECU chiptuning is the process of reprogramming your car's engine control unit to optimize fuel injection, ignition timing and turbo boost. Done right, it improves power, torque, throttle response and even fuel economy without touching the hardware.
Is it safe for my engine?
Our calibrations are written with a real safe margin that respects the limits of your hardware. Every file is dyno-tested before delivery. As long as your car is in good mechanical condition, a Stage 1 tune is fully reliable for daily driving.
Will it void my warranty?
A modified ECU can affect the manufacturer warranty. Most workshops can detect a modified file in their software, so we recommend chiptuning on cars that are out of warranty — or accepting the risk if yours is still under warranty.
How long does delivery take?
Most files are delivered in under an hour during our working hours (7 days a week). Complex requests like Stage 2 with multiple extra options can take a bit longer. You will be notified the moment your file is ready.
Do I need special tools to flash the file?
Yes — you need a flashing tool like KESS, K-TAG, AutoTuner, MPPS or similar. If you don't have one, your local tuning shop probably does. We provide the modified file; flashing it back to the ECU is done with the same tool you used to read it.
What payment methods do you accept?
We accept credit and debit cards, bank transfers, and crypto. Payment is made via credits — you buy credits once and use them across multiple files.
Can I revert the tuning?
Yes. We always recommend keeping a backup of your original ECU file. You can flash the original file back at any time to return your car to factory state.
Do you cover my car?
We cover 130+ brands and thousands of engines. Use the vehicle selector at the top of this page — if your engine appears in the database, we can tune it.
