Housing the only 4wd dyno south of Christchurch APET can tune a very wide range of vehicles and ECUs including many factory ECUs as well as most common aftermarket ECUs.
Currently we hold the world record for the most power made with a Nissan GTR running solely on a factory tuned ECU at 1,160hp
APET utilizes a modern, fully computerized torque performance chassis dynamometer to perform all dyno tuning. The capabilities of this dyno allow us to log and graph a wide range of data including power, torque, boost, air fuel ratios, engine knock, exhaust gas temperature, pressure ratios and many others depending on the vehicle management system.
Dyno tuning is a must for getting the most out of your vehicle especially when it has been altered from its factory state. Changing aspects of your vehicle can significantly increase its performance but by getting it tuned after these changes are made, you can get even more out of your other modifications. Dyno tuning can not only give your car more power but can significantly increase fuel economy which in itself is a huge saving.
Every engine behaves and responds differently and by knowing what it needs and wants we can custom tune it to perform at its best at all times. By adjusting the parameters of the Engine control unit (ECU) changes in fuel supply and ignition timing can be altered to where they work best and give the most response and power output. By controlling the amount of load or resistance on the engine, the dyno has the accuracy to hold an engine at any load level or rpm within 50rpm to allow for monitoring of air fuel ratios and engine knock to ensure a complete, safe tune.
