We will ensure your vehicle is operating at peak performance in all load conditions, because we can simulate most of the driver functions on our chassis dynamometer.

As a general rule any 4WD vehicle has losses of approximately 45% of power by the time it gets to the wheels. Remember - we drive the car - not the engine. A factory spec 100kw engine is likely to only produce 55kw on the road.

We measure tractive effort in Newtons of Effort at the wheels. This is because your car has gears or a torque converter that modifies the tractive effort with every gear change, e.g. 1st gear low range may produce 20,000 newtons of effort on full power however 5th gear full power may not exceed 1,500 Newtons.

Data Acquisition

The dyno's computer system captures information and records it for analysis. Once recorded, this data can be retrieved for subsequent tuning. The data includes the following:

Vehicle speed

Ambient air temperature

Power output

Tractive effort

Engine speed

Induction air temp before and after intercooler

Air/fuel ratio and 4 gas exhaust analysis

Ignition oscilloscope readings

Graphing Engine Performance

The "shootout" system provides a graph of "before tune" and "after tune" performance. In most cases we run the vehicle in 3rd gear (manual transmission), 2nd gear (automatic) accelerating from 40 kph to peaking out.
