Custom ECU & TCU
Tuning.
Custom ECU and TCU tuning recalibrates a vehicle's engine and gearbox control software to suit its hardware, fuel and intended use. It is for drivers seeking vehicle-specific calibration rather than an off-the-shelf file. Etuners offers this service from its Smithfield, Western Sydney workshop by appointment, subject to confirming vehicle compatibility.
How is custom calibration different?
At Etuners Australia, we don't believe in "one size fits all" software. A generic flash file cannot account for the subtle differences in engine health, fuel quality, specific hardware modifications, or the exact way you intend to use the vehicle.
Our calibration process starts with a vehicle health check and data logging session. We then develop software for the Engine Control Unit (ECU) and, where supported, the Transmission Control Unit (TCU). [TO CONFIRM] Vehicle-specific limits and compatibility must be agreed before work; no performance or reliability outcome is guaranteed.
Engine Calibration (ECU)
We adjust hundreds of parameters including ignition timing, fueling, boost control, and torque management strategies. Our specialty lies in modern direct-injection turbocharged engines, particularly European platforms.
- Boost target optimization
- Ignition timing advancement
- Air/Fuel ratio corrections
- Launch control implementation
- Pops & bangs / overrun (optional)
- Speed limiter removal
Gearbox Calibration (TCU)
For twin-clutch transmissions (DSG, S-Tronic, DCT), a TCU tune is highly recommended alongside an ECU tune to optimize shifting logic and increase clutch clamping pressure.
- Increased clutch clamping force
- Optimized shift points
- Faster shift speeds
- True manual mode (no auto upshift)
- Raised torque limiters
- Custom launch control RPMs

Got Questions?
The general FAQ covers ECU and gearbox remapping, including safety, fuel economy and returning to stock. Contact the workshop to confirm requirements for your vehicle.
Read the FAQIs ECU tuning safe for my Audi?
Tuning safety depends on your Audi's mechanical condition and calibration quality. A mechanically healthy vehicle is important, but no tune is a guarantee against problems. [TO CONFIRM] Engine-specific inspection checks and calibration limits must be confirmed before work.
What's the difference between Stage 1 and Stage 2?
[TO CONFIRM] Etuners' exact Stage 1 and Stage 2 definitions, hardware prerequisites and calibration inclusions must be confirmed for your vehicle. A stage label alone is not enough to select a tune; agree on the hardware, fuel and intended use before booking.
Does DSG tuning affect warranty?
Changing factory transmission software can affect a manufacturer's warranty, as explained in the existing Etuners FAQ. [TO CONFIRM] The implications for your vehicle and its warranty terms must be checked before booking. No guarantee of retained warranty coverage is made.
How long does a remap take?
The existing Etuners FAQ describes a typical ECU or TCU calibration as being completed within a day, including checks and verification. Complex custom projects may take longer. [TO CONFIRM] The actual turnaround and availability for your vehicle must be agreed before booking.
Do I need 98 RON fuel after tuning?
The required fuel depends on the calibration and vehicle configuration. [TO CONFIRM] Etuners must specify the approved fuel and RON requirement for your particular tune. This page does not confirm that either 95 or 98 RON is suitable for your vehicle after tuning.
Can my ECU or gearbox software be restored to stock?
The existing Etuners FAQ states that original ECU and transmission software can be restored. [TO CONFIRM] Confirm the availability, process and any restoration charges for your vehicle before relying on this option. No vehicle-specific restoration commitment is made here.
Which vehicles and gearboxes can Etuners tune?
The site describes custom calibration for European vehicles and a range of DSG, DCT and automatic transmissions. [TO CONFIRM] Exact model, engine code, model year, transmission and software-version compatibility must be confirmed. The brand pages do not replace an individual vehicle check.
