The vehicle is driven onto our specialised platform called a dynamometer or “dyno”. The dynamometer is equipped with rollers that allow the vehicle's wheels to turn freely while the vehicle remains stationary. Sensors are attached to the vehicle to measure various parameters such as engine speed, torque, horsepower, air-fuel ratio, and exhaust gas temperature

With the vehicle secured on the dynamometer, the engine is run through a series of tests to measure its performance under different conditions. This may include testing acceleration, speed, and load at various throttle positions. 

As the engine runs on the dynamometer, data is collected in real-time from the sensors attached to the vehicle. This data provides valuable information about the engine's performance and allows the rolling road tuner to make adjustments to optimise its operation.

Based on the data collected during testing, our technician makes adjustments to the engine's electronic control unit (ECU) or engine management system. These adjustments may include optimising fuel and ignition timing, adjusting air-fuel ratios, and modifying other parameters to improve performance, drivability, and fuel efficiency.

Rolling road tuning is often an iterative process, with the tuner making incremental adjustments and retesting the vehicle to assess the impact of those changes. This process continues until the desired level of performance and drivability is achieved.

Once the rolling road tuning process is complete, the vehicle may undergo further tests to verify its effectiveness. This may include additional dynamometer runs or on-road testing to ensure that the vehicle performs as expected under real-world conditions. Upon completion of the rolling road tuning process, a graphical print out of the initial vs. optimised performance will be provided, which will show the brake horsepower (BHP) and Torque gains achieved.
