Welcome

Welcome to Chiptuning NZ, where real chip tuners with real experience turn your standard car into one that runs the way it always should have. After we have spent a few hours 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. We love to see the smile on a customer's face after they have taken delivery of their car.

We thoroughly enjoy what we do with engine control unit ECU software optimisation. Unlike our competitors, we upgrade the ECU on each car we do individually – each car is tuned based on customer requirements, type of fuel used, mileage covered 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 many hours on each ECU 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 with our unusual petrol and diesel brew.

Our diesel 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. This is the only way to achieve safe and significant torque and efficiency gains on a turbo diesel. Please see "Warning" for further details.

Chiptuning NZ is available to everyone in New Zealand. We are a mobile service that covers most main centres, including Auckland, 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.

Chiptuning NZ and its parent company Autopassion Ltd. has worked closely with new car dealerships as well as car enthusiasts and motorsport workshops for many years. This experience allows us to optimise each chip tuning to make safe and proven performance upgrades that will enhance the enjoyment of your car.
