Our services - A full suite of tuning solutions & support for your business
At Code & Tune NZ, we provide professional ECU tuning files and custom calibration solutions for workshops throughout New Zealand. Whether you’re tuning passenger vehicles, commercial vans, heavy trucks, agricultural machinery or industrial equipment, our experienced calibration team delivers reliable solutions backed by genuine technical expertise.
Using industry-leading Alientech, Autotuner and MagicMotorSport programming equipment and over a decade of WinOLS calibration experience, we offer everything from performance tuning to advanced ECU modifications and emissions solutions. Every file is developed with reliability, drivability and vehicle compatibility in mind, giving our dealers complete confidence when delivering services to their customers.
Stage 1
Stage 1 tuning is our most popular performance upgrade. Designed for standard vehicles with no hardware modifications, a Stage 1 calibration improves power, torque, throttle response and overall drivability while maintaining excellent reliability for everyday use.
Stage 2
For vehicles fitted with supporting performance modifications, our Stage 2 tuning files unlock additional performance by optimising the ECU calibration to suit upgraded hardware such as exhaust systems, intercoolers or induction components.
DPF Solutions
We provide professional DPF calibration solutions for supported off-road, motorsport and export applications. Our experienced technicians ensure each calibration is carefully developed to suit the specific ECU and vehicle.
EGR Solutions
Our EGR solutions are designed to professionally recalibrate supported ECUs where EGR functionality requires modification for suitable applications. Every file is produced using proven calibration techniques for reliable operation.
AdBlue Solutions
If a supported vehicle requires an SCR or AdBlue calibration solution, our experienced team can provide professionally developed software modifications for a wide range of diesel applications.
DTC Removal
Diagnostic Trouble Code (DTC) removal allows specific fault codes to be professionally disabled within supported ECU software where appropriate. This is often carried out alongside other ECU modifications for specialist applications.
Speed Limiter Removal
We can modify supported ECUs to remove or adjust factory speed limiters where permitted and appropriate, allowing vehicles to operate without manufacturer-imposed speed restrictions.
RPM Limiter Removal
Our RPM limiter modifications allow supported vehicles to have their engine speed limits professionally adjusted to suit performance or specialist applications.
Start/Stop Disable
Many drivers prefer to permanently disable automatic start/stop functionality. Our ECU solutions can disable this feature on supported vehicles, improving convenience without requiring the driver to switch it off every time they drive.
Swirl Flap Solutions
We provide professional software solutions for supported vehicles fitted with swirl flap systems, helping workshops complete repairs and modifications with correctly calibrated ECU software.
TVA Delete
For supported applications, we can provide throttle valve actuator (TVA) calibration solutions as part of a professionally developed ECU modification.
Launch Control
Launch Control allows compatible performance vehicles to achieve more consistent standing starts by controlling engine speed during launch. Our custom calibrations are carefully configured to suit each supported vehicle.
Pops & Bangs
Popular with performance enthusiasts, Pops & Bangs software modifies the engine calibration to create exhaust crackles and overrun effects on suitable petrol vehicles. We offer a range of customisable options to suit different customer preferences.
Popcorn Limiter
The Popcorn Limiter feature modifies the engine’s rev limiter characteristics to produce the distinctive “popcorn” exhaust note on compatible diesel vehicles, making it a popular option for show and motorsport applications.
Sports Displays
On supported vehicles, we can activate or recalibrate factory sports display functions, allowing drivers to access additional performance information through the vehicle’s infotainment system.
Our tuning services are available for a wide range of applications, including:
Cars, SUVs, Vans, Performance vehicles, Diesel utes, Trucks, Buses, Agricultural machinery, Construction equipment, Marine engines, Industrial and heavy-duty machinery
