Car Performance Tuning

Increase Your Car’s Performance

Welcome to Chiptuning NZ, where real ECU chip tuners with real experience turn your standard car into one that performs the way it always should have. After we have spent time remapping and power tuning your car, we will give it back to you with more power, more torque, more acceleration and smoother engine response. If it is a turbo diesel, economy will improve and torque gains will be tremendous. Turbo petrol cars respond brilliantly to clever chiptuning with breathtaking torque and power increases. Modern normally aspirated (non turbo) petrol cars also benefit greatly from an ECU chip remap, with increased torque delivery across the rev range, more power and better throttle response.

Real Power Tuning

We thoroughly enjoy what we do with ECU chip software optimisation. Unlike our competitors, we re-flash the ECU on each car we do individually – each car is custom tuned based on customer requirements, type of fuel used, mileage covered, modifications and condition of the engine/ drivetrain. We don't turn up and read the ECU then come back later or the next day with a file we bought from an online data base or some company in Europe – that is not tuning. We will spend time on each ECU remap, customising the software for each car. Work will normally start in the morning and the car will be completed by the middle of the afternoon. Ready-made software from overseas does not work well enough to maximise torque at all engine speeds.

Diesel Power

Our diesel ECU chip tuning does not involve fitting a tuning box or device to the fuel rail. We do it the correct way by optimising all fuel, boost and limiter parameters in the ECU. This is the only way to achieve safe and significant torque and efficiency gains on a turbo diesel. Please see "Caution" for further details.

Near all Major Centres

Chiptuning NZ's engine ECU remapping service is available to everyone in New Zealand. We are a mobile facility chip tuning in Auckland, as well as chip tuning in Wellington, Christchurch and Dunedin; whereby we use full workshop facilities while your car is in our care. If you are in an area where you are unable to come to us, you can send us your ECU and we can send it back tuned overnight.

Real Experience

Chiptuning NZ and its parent company Autopassion Ltd. has worked closely with new car dealerships as well as car motorsport workshops and car enthusiasts for many years. Chiptuning NZ has been chip tuning and engine tuning European and turbo diesel cars in Auckland and Wellington longer than any other company. This experience means we know the cars we are working on and understand the latest ECU technology, which allows us to optimise each chip tuning to make safe and proven performance upgrades that will enhance the enjoyment of your car
