N Got Questions?

Frequently Asked Questions

Everything you need to know about our chiptuning files and custom remap service.

What is ECU file tuning?

ECU file tuning (chiptuning/remapping) modifies the Engine Control Unit software to optimize performance. We provide custom tuning files covering diesel tuning, petrol performance, and emissions solutions. Our files modify calibration tables for fuel injection, boost pressure, and throttle response.

How fast do you deliver tuning files?

Most tuning files are delivered within 30-60 minutes. We prioritize fast turnaround because time matters. Complex tuning requests or rare ECU types may take longer, but same-day delivery is guaranteed for standard requests. You'll receive an email notification when the tuned file is ready.

What vehicles do you support?

We support most European, American, and Asian vehicles including cars, trucks, motorcycles, agricultural equipment, and commercial vehicles. This includes all major brands like BMW, Mercedes, Audi, VW, Ford, GM, Dodge, Toyota, and many more. We work with all major ECU manufacturers including Bosch, Siemens, Continental, Delphi, Denso, and Marelli.

Do you offer TCU/gearbox tuning?

Yes, we offer TCU (Transmission Control Unit) tuning for automatic gearboxes. This includes faster shift times, higher torque limits, and optimized shift points for improved performance and drivability. TCU tuning is especially popular for DSG, S-Tronic, PDK, and DCT transmissions.

Is ECU tuning safe for my engine?

Yes, when done professionally. Our tuning files are dyno-tested and developed in-house by expert calibrators. All modifications stay within safe parameters for the specific engine and components. We don't use generic or slave files — every tune is custom calibrated for the vehicle you're working on.

What is the difference between Stage 1, Stage 2, and Stage 3?

Stage 1 tuning optimizes your stock vehicle for better performance - typically 20-30% more power with no hardware changes required. Stage 2 requires hardware modifications like an upgraded exhaust or intercooler and can deliver 30-50% more power. Stage 3 involves major upgrades like larger turbochargers and is designed for maximum performance.

Do you offer a warranty?

Yes, we offer a 100% satisfaction guarantee. If you're not happy with your tune, we'll revise it until you are satisfied at no extra cost. We also provide free revisions for any issues that arise after flashing your tuned file.

What tuning tools do you support?

We support all major master tuning tools including Autotuner, KESS V2/V3, KTAG, CMD Flash, Alientech (KESSv3, K-TAG), New Genius, Magic Motorsport (Flex, X17), PCMFlash, BitBox, and many more. If you're using a master tool, we can tune your files.

Do you offer volume discounts for tuning shops?

Yes! Unlike other services that require you to buy credits upfront, we offer automatic volume-based stage pricing. The more files you order, the better your per-file rate. No prepayment required — discounts are applied automatically based on your volume. View our stage pricing →

Is this service for professional tuners or DIY?

Our trade file service is designed primarily for professional tuners, garages, and tuning shops — you'll need a master tuning tool to read and write ECU files. If you're a vehicle owner looking for tuning, we also sell personal OBD tuners that let you tune your own vehicle. Browse Personal OBD Tuners → or contact us for a custom quote.
