Why Rolling Roads Are a Great Way of Tuning Car Performance

Rolling roads are a perfect way to figure out how much power is left on your car. It also tests a car’s performance under load. This is something that car owners do with old vehicles they bought second-hand

A car is fitted to the measuring equipment and secured onto the rollers. Then with airflow, exhaust extraction, and temperature-controlled, the car on the rolling road is set to create a replication of the real driving environment.

The car performance can be analyzed, adjusted then retested to assess accurately or diagnose issues the car could be having before fixing.  It can be used to measure the output of a vehicle, or it can also be used to diagnose issues that the car may be having. 

A favored use of a rolling road is to test the performance of a car with the dyno equipment, change the vehicle in any way, then retested over and over until the desired car performance is achieved. 

Through rolling road/dyno, the operator ensures that the engine is safely running and fixes issues that may cause early wear or breakage. Of course, this can lead to an efficient performance of the car. Time on the rolling road/dyno can be broken into a few various categories.

The operator can use the standardized equipment to measure the air and fuel ratio at any rev range allowing the engine to be tuned neither too rich [power draining and un-economic] nor too lean [damaging]. The operator can diagnose symptoms, such as poor operation, power drops, flat spots, and identify where power peak and torque are produced.

Dyno Runs

Dyno runs or tests are suitable for people who would like to know how much torque and horsepower their vehicle is generating at the wheels. 3 runs are ideal for establishing a baseline for torque and horsepower. It is worth mentioning that this procedure doesn’t tune your car, but is just a diagnostic and informative tool.

Dyno Tuning

This involves full remapping of the ECU, which allows the operator to maximize the engine to safely generate an ideal [usually maximum] torque value at all sites through which an engine operates. The operator manipulates the ECU-controlled spark, injections, as well as other parameters to adjust for optimum idle control, cold start control, throttle response, etc. 

However, to make the most out of the rolling road/Dyno, there are a few things you need to know. Here are things you need to know in advance if you are considering rolling road/dyno:

1. Understand what it entails

We have mentioned up here what rolling road/dyno entails- how the whole procedure is carried out. You can go through it again.

  1. Choose the right shop

Choosing the right shop is crucial if you want to want a successful rolling road/dyno session. Look for a reputable shop such as Cooksport. You can achieve that by doing your own research. 

  1. Prepare for the session

If you won’t have a productive and satisfying visit to the shop, make sure you prepare your car for the rolling road session. Make sure the car is in good shape. It should not have any flaws. This will help you get the best reading possible from the dyno pulls.

Final thoughts

Now that you understand how rolling roads can tune your car performance, it is time to look for the right tuner to tune your car. You will be surprised at how significantly your car performance shall have improved.
