”SIP-Dyno“ is a consequent advancement of the “GSF-Dyno” software by Tom Avsic. SIP-Dyno is a software that helps you determine the performance of a scooter. It works very similar to the software of a dyno, only that with the SIP-Dyno, your test runs will take place on the street and not on the dyno. Instead of accelerating a massive metal cylinder like on a dyno, the scooter is being accelerated on the street while riding it. Put simply: get on your scooter and ride at full throttle. The quicker the acceleration of the scooter, the greater its performance.
So the software has to determine how fast the scooter is accelerating and this is done the easiest way by the digital signal processing of the engine noises. Some of you will think now: “I see, the louder, the higher the performance of the engine, now that’s more of the common gibberish!” We all learned early through our mechanics career that this just ain’t so. Sound levels really are no indication for performance at all. The SIP-Dyno can measure the rpm of the engine. The faster the rpm increases, the better the performance of the engine (all other conditions being identical). Luckily, the gear ratio of our Vintage scooters remains the same as long as there is no shift of gears. This way, the speed can be calculated from the rpm just as you can then calculate the performance by the change of speed which equals acceleration. To obtain the most realistic performance value possible, it is recommended to enter the values of overall weight, tire circumference and gear ratio as precisely as possible.
Improvements of the new version:
Real time reporting: you can put the laptop on your lap, run the measuring and watch as the curve develops. Moreover, the reporting is more clearly arranged and more informative while the interface is also more userfriendly.
Of course the SIP-Dyno comes for free just like the GSF-Dyno.
