About Radio FM 90s

Tested and well reviewed in Scootering Januar 2013 by Sticky, author of the Complete Spanners Lambretta manual

Sticky: "The fact that it works at all - let alone working this well - is just plain wizardry"

SIP HorsePower Dyno(MicroDyno) for Android -unlike all other Dyno Apps out there- doesn't use the acceleration or GPS sensor, because both aren't exact enough to achieve a good measuring result.

SIP HorsePower Dyno(MicroDyno) can measure the rpm of the engine by analyzing the exact frequency, recorded with the microphone (Screenshot 1: in the middle you can clearly see accelerating in 1st, 2nd and 3rd gear).
The faster the rpm increases, the better the performance of the engine. The gear ratio of our rides 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, you need to enter a couple of values as precisely as possible:

- overall weight
- tire circumference
- air pressure
- temperature
- gear ratio
- Cw-Value (Tough one, but if you don't change this for different runs, you get repeatable and combarable results, this value moves the resulting curve on the y-axis, so it can be used to calibrate the dyno. If this value is way off the result can be off about 2 PS)

If you know the Windows programs SIP Dyno and GSF Dyno, you know how exact these measurements are.
You can find a couple of comparisons between GSF Dyno, this App and a real dyno (P4) at www.siphorsepowerdyno.de and in the Scootering from January 2013.


- This App only works if there is no shift in gears. The method doesn’t work with automatic scooters.

- This App might not work for cars. It was tested on Vespas and Lambrettas which have a 1 cylinder 2 stroke engine.

Please be aware that this is a very technical App. I cut the important things down as much as i could and added a "?-Button" on every page inside the App. Please read the information carefully.
Check out www.siphorsepowerdyno.de or my YouTube-Channel for a tutorial.
If you have any problems, contact me and I will guide you through.

Important: There is a software failure in some Samsung Galaxy Ace and Samsung Galaxy Young devices.
I included a fix for this, in Settings-> scroll to bottom ->"Samsung Fix"
