Engine Braking Analysis in Tuning

Hey folks, I’m exploring how engine braking can be tuned more precisely for motorsport applications. Is there a way to analyze engine braking performance on a dyno? Or is this something that only really comes through road testing?

You can absolutely test engine braking on a dyno — it just requires the ability to apply reverse load and control deceleration. Analyzing that aspect of your car’s performance gives real insight into downshifting behavior and torque drag. With modules Dynotest https://dynotestpro.com/ , it’s possible to simulate deceleration and observe how much braking force comes from engine drag at different RPMs. That data is extremely useful for track setups where braking balance is key, especially when paired with ECU strategies for rev-matching or lift-throttle scenarios. The results are highly tunable once you can see what the engine’s actually doing under coast-down.
