DYNO TUNING The Dyno Doesn’t Lie When It Comes to Measuring Horsepower
At the core of every dyno facility is the dynamometer or dyno, which is essentially a measuring device used to determine the power, torque, speed and more that an engine is capable of. Back in the day when there weren’t any dyno facilities in the country, everything was just a “guesstimate” of how much an engine makes based on countless adjustments and never-ending road tests. But because of independent dyno facilities such as Dynopro Philippines which opened in 2016 and will soon be opening its third branch, this completely eliminated any guesswork, as it is capable of exactly measuring vital engine parameters. Using the dyno’s data acquisition and engine function graphing techniques, you get a snapshot of the real-world performance of your engine. The first step towards making more power and make the engine more efficient would be the non-tuning part or the baseline dyno. The second step would be performance dyno tuning whose main purpose is to achieve the desired power levels by changing or altering the ECU program. Aside from gaining more power and fuel efficiency, dyno tuning can be used as a diagnostic tool to better understand what the engine needs or if there are any problems with it.
Take it from noted tuner Leo Carlo San Juan of Speedworks Engineering as he stresses the importance of dyno tuning, “Dyno tuning is important because the cars can be pushed to their limit safely as compared to street tuning. Cars now can easily hit 200 kmh and it is unsafe for street tuning. With track tuning you have limited time to prepare since you usually take turns with the motorcyclists who rented the track as well.”
The bottom line here is that it’s better and safer to get a baseline dyno first before adding any amount of performance work, upgrades and tuning. This is so you can maximize power but balance it out and still maintain efficiency. Once the modifications are made, the vehicle can then go back on the dyno to check its current power output and if there’s a chance more could be gained. The best part here is that no guessing is required as everything is measured.
In my opinion, this as an important starting point that should be done before doing any amount of engine modifications or tuning. What this does is simply measure the wheel horsepower, torque and other engine parameters such as, engine rpm, air-fuel ratio, manifold pressure and more. All the data gathered will serve as the basis for comparison against subsequent engine adjustments or modifications. This will help verify if there are any substantial power and torque gains. More importantly, it will determine if the modifications made did or didn’t increase the performance at all. What’s more, having a baseline dyno will give you a better idea and help you decide what engine modifications are needed and should be done to make the engine generate even more power.
Performance Dyno Tuning
If the baseline dyno run is more like a “before” figure, then this is the “after” figure once all the engine modifications has been done and is ready to be tuned. This is where the tuner makes real-time adjustments to the engine’s basic parameters such as ignition, fuel, spark, and boost for turbocharged or supercharged engines. This is mostly achieved through a programmable Engine Control Unit (ECU) or a Piggyback ECU Module to allow the stock ECU to be manipulated. By making a series of runs or pulls on the dyno, the tuner can make the appropriate changes on the engine parameters on his laptop as he sees fit until he gets the desired target output based on the power and torque graphs that are displayed on the monitor so there’s no guessing.
Stock, Modified and even Motorcycles
Unlike before where the majority of the cars that were dyno tuned was purely for racing and getting more performance, today’s modern everyday vehicles can also be remapped or ECU tuned. Keep in mind that not all engines perform exactly the same as each engine runs and performs differently. Aside from getting increased levels of power and torque, the most important thing to be gained from doing so, is that it will make the stock engine perform more efficient and optimally. In most cases and depending on the driving habits, the engine even becomes more fuel efficient.
When it comes to dyno services, Dynopro Philippines is an independent dyno facility that started in 2016, with its first branch along Mindanao Avenue in Quezon City. A second branch was put up in Sucat, Paranaque just last year. In 2023 they will soon be opening their third Dynopro branch in Quirino Avenue in Manila. Dynopro uses a state-of-the-art Dynojet Chassis Dynamometer that’s considered as the aftermarket industry standard when it comes to measuring horsepower and torque. Dynopro’s dyno can accommodate front or rear wheel drive, two-wheel drive or all-wheel drive vehicles. This even includes motorcycles as they have a Dynojet Motorcycle Dyno as well. A well-trained staff ensures the safety of your car and also the people around during the tuning process. Dynopro even has a tuner directory to help clients link directly with them. Doing so broadens the awareness towards more motorists regarding ECU tuning for car and motorcycles. Dynopro is fully committed to giving the highest quality of service and the best dyno facility to their clients. This is why they guarantee high credibility, consistency, and customer satisfaction.
