Standalone ECU Wiring & Remaping Service

Your build deserves more than a plug-and-play solution.

At NOFUXGVN, we deliver a complete standalone ECU service, covering custom wiring and full ECU remapping, built specifically around your engine, your setup, and your performance goals. This service is strictly for vehicles running standalone engine management systems — no factory ECU remapping and no OBD tuning.

We start with the foundation: proper wiring. Whether building a loom from scratch or correcting an existing one, we ensure correct sensor integration, clean signal routing, proper grounding, and stable power supply. Reliable wiring is critical — without it, no tune is safe or consistent.

Once the hardware is confirmed, we move to custom ECU calibration. This includes fuel mapping, ignition timing optimization, idle and cold-start control, throttle calibration (DBW or cable), boost control where applicable, and essential engine safety strategies. Every calibration is developed specifically for your engine configuration, injectors, fuel type, and intended use — never generic files.

This service is ideal for engine swaps, turbo or supercharged builds, motorsport vehicles, and high-performance street projects that have outgrown factory management. The focus is smooth drivability, controlled power delivery, and long-term reliability.

NOFUXGVN tuning is not about chasing numbers — it’s about control, precision, and confidence every time you turn the key.

Risks & Disclaimer

Standalone ECU wiring and tuning involve non-factory modifications and carry inherent risks. Increased performance and custom calibration may place additional stress on the engine, drivetrain, and related components.

NOFUXGVN is not responsible for failures resulting from mechanical wear, improper installation, existing faults, unsuitable supporting modifications, or operation beyond component limits. The vehicle owner is solely responsible for ensuring the engine and all supporting systems are mechanically sound prior to service.

This service may not be compliant with road-use regulations in all regions and is intended for motorsport or off-road use where applicable. By proceeding, the customer acknowledges and accepts all associated risks.
