What is Dyno Tuning?

When it comes to tuning an engine we need a way of measuring the engine power and live outputs to see how the engine is performing and responding to the tuning. At DAS Tuning we have a state of the art chassis dyno to measure torque and horsepower and provide real tuning results.

Dyno Tuning

When we think of tuning, most people immediately think of a dyno and when we have the option to tune on a dyno, this is usually going to give you the best possible results. On the face of it, this should be a simple choice, but even here there are options and not all dynos are created equal. For the purposes of this blog, we will be looking at chassis dynos where the engine is installed in the car as these are still the most popular. What is a dyno? In short, the dyno is used to apply a load to the engine to replicate driving the car on the road. As well as being able to apply a load to the engine, the dyno will also be able to measure the torque being produced and from this, the engine power can be calculated. Depending on how smart or advanced the dyno is, it will also be able to log parameters such as boost pressure and air fuel ratio and provide the tuner with torque and power graphs that can be analysed after a run. Our 4WD dynodynamics dyno has the functions and capabilities to perform advanced logging and engine load which allows the tuner to adjust the tuning more accurately. Chassis dynos calculate load and torque in different ways – for example testing the same car in the same environment on a Dyno Jet dyno and a Mustang Dyno will produce different results in power and torque. As such the main goal of a dyno is to provide a quantifiable benchmark for before and after to analyse how particular software and/or hardware changes affect the car.
