Why Christchurch
Supercars coming to Ruapuna has brought a lot more attention to motorsport in Canterbury, and local workshops are busier for it. They're seeing everything from baseline dyno runs to full race builds.
Work out what your project needs
Before you book, work out which kind of specialist you need. Several well-known Canterbury names have changed what they focus on.
ECU parts and fuel systems
Some shops now focus on supply rather than tuning. NZEFI, for example, is mainly where you go for aftermarket electronics and fuel system parts.
- Go here for: Link or Haltech ECUs, fuel system hardware, and injector flow testing and ultrasonic cleaning.
Dyno tuning and remapping
If the build is done and the ECU needs setting up, look for a workshop with its own dyno.
- Hub dynos: DCH Automotive and Flame Performance use hub dynos, which bolt to the wheel hubs. They give accurate numbers on powerful cars without tyre slip.
- Roller dyno: R.E. Sinclair runs a 4WD Dyno Dynamics roller and does everything from engine rebuilds to rewiring and aftermarket ECU tuning.
Race prep and engineering
If you're entering sanctioned events, use a shop that does race prep.
- Chassis and setup: CWR Motorsport in Rangiora does race car engineering, including corner weighting and suspension geometry.
- Subaru: CroweSport is a long-standing South Island Subaru specialist with a big rally and circuit background.
European cars
Modern BMW, Audi and Mercedes-Benz models need specific diagnostic tools and software that a general workshop may not have.
- Leading Edge Automotive: diagnostics and performance tuning for European cars.
- Eurolab: diagnostics and performance upgrades for European models using genuine parts.
What to ask before you book
- Equipment: do they have the software for your ECU, and what kind of dyno do they use?
- Compliance: do they know the LVV certification thresholds, so your car stays road legal?
- Pre-tune checks: a good tuner checks the engine's health first, with a compression test and a smoke test, before the car goes on the dyno.
