Our Services
Performance ECU Tuning Files
We provide high-quality, dyno-tested, Stage 1 and Stage 2 tuning files to trade customers. These tuning files are designed to optimise the brake, horsepower, and torque of the vehicle, giving boosts of up to 30%.
Economy Focused Tuning Files
If your business deals with lots of fleet vehicles and HGVs where economy matters more than raw power, we can help with these tuning files also. We are specialists in optimising for fuel economy.
DPF, EGR & Adblue Solutions
We also provide software solutions for common faults and problems like DPF, Adblue, EGR and DTC removal.
Premium ECU Tuning Files for Professional Workshops Across New Zealand
Welcome to Code & Tune NZ, your trusted supplier of professional tuning files in New Zealand. We provide high-quality ECU tuning files, dealer support and advanced vehicle programming solutions to independent workshops throughout New Zealand and around the world.
Our mission isn’t to become the country’s largest tuning workshop. Instead, we’re building New Zealand’s leading technical support network for professional automotive workshops, giving our dealers everything they need to offer premium ECU remapping, performance tuning and emissions solutions under their own brand.
Whether you’re looking for Stage 1 and Stage 2 performance tuning, DPF solutions, EGR solutions, AdBlue solutions or custom ECU calibrations, Code & Tune NZ provides the expertise, technology and technical support to help your business grow.
Professional Tuning Files Backed by Real Technical Expertise
Not all tuning file providers are the same.
Many simply upload generic files with little understanding of the vehicle they’re calibrating. At Code & Tune NZ, every tuning file is backed by years of hands-on experience in diagnostics, ECU programming, electrical fault finding, oscilloscope analysis and custom calibration.
Our technical team works on real vehicles every day. We understand the challenges workshops face because we’ve solved them ourselves.
When you need assistance, you’re speaking directly with experienced technicians—not a sales team, marketing company or overseas call centre.
That makes us far more than just another tuning file supplier. We become a technical partner that’s invested in your success.
Why Resell Our Tuning files?
High-Profit Services with Low Overheads
ECU tuning offers excellent profit margins without the need for large amounts of stock or expensive premises. Once you have the appropriate programming equipment and access to professional tuning files, each completed job can generate significant profit while requiring relatively little time to carry out.
Increase Revenue from Existing Customers
Your existing customers already trust you with servicing, repairs and diagnostics. By adding ECU remapping and emissions solutions to your services, you can increase the value of every customer visit without spending heavily on attracting new business. It’s a simple way to maximise the potential of your existing customer base.
Meet Growing Market Demand
More vehicle owners are looking to improve performance, fuel economy and drivability than ever before. At the same time, commercial operators are seeking reliable solutions for diesel vehicles and machinery. Offering professional ECU tuning allows your workshop to capitalise on a growing market while staying ahead of your competitors.
Stand Out from Competing Garages
Offering professional tuning services helps differentiate your workshop from others in your area. Customers increasingly prefer businesses that can provide a complete range of automotive services under one roof, making ECU programming an excellent way to strengthen your reputation and attract new clients.
