What do I need to get going?

The electronics you need to control the brake and produce power curves with your dyno system are:
For Inertia dynos (no brake):

  • YourDyno instrument (the blue box)
  • RPM sensor
  • RPM sensor trigger wheel

For Eddy current brake dynos:

  • YourDyno instrument (the blue box)
  • RPM sensor (one per brake)
  • RPM sensor trigger wheel (one per brake)
  • Load cell (one per brake)
  • Eddy current power supply (one per brake)

For water brakes:

  • YourDyno instrument (the blue box)
  • RPM sensor
  • RPM sensor trigger wheel
  • Load cell
  • Electrically controlled water valve (or manual if preferred)
  • Stepper motor driver and stepper power supply to control valve
  • …or RC servo or other means of controlling the valve

For any other braked dyno;

  • YourDyno instrument (the blue box)
  • RPM sensor (one per brake)
  • RPM sensor trigger wheel (one per brake)
  • Load cell (one per brake)
  • + whatever you use to control your brake

Optional additions:

There are many additions you can choose, such as Wide band Lambda sensors, temperature sensors, OBD2 converter, CAN bus converter, etc

    Hi,Jostein .I am not computer savy. does yourdyno include detailed manual for installation,needed hardware,software etc.for hooking up 2 lambda’s,8 egt’s. oil pressure,fuel pressure,manifold pressure,vacuum,airflow and water temp.Also I notice on ebay stepper motor controller kits all seem to have feedback,would this be acceptable. Would a globe valve be suitable for a water brake. Thank you.

      Hi, there is quite some explanation in the program itself, plus in the wiki. That said, YourDyno is made to support all kinds of dynos and sensors, and there are so many combinations that you will not find a specific text that covers exactly your setup. It is not difficult to set up, but you may want to have help from someone who knows dynos and computers for the setup. YourDyno is very easy and intuitive to use!
      Your list of sensors is quite long. You may want to start with just the basics, and then add on. The YourDyno box supports 3 x 0-5V sensors, this can be pressure sensors, flow, water temp, etc. You just need a sensor that outputs a value between 0-5V. If you need more than 3 analog channels, add one of these: https://www.velleman.eu/products/view/?id=384006, which gives 5 more channels. For 8 thermocouples, you can use this box which the YourDyno software can read: https://www.ecumaster.com/products/egt-to-can/.
      No, there is no feedback on the stepper. Steppers are quite often run without feedback, and that is ok when set up correctly. We run our water brake without feedback and it is no problem.
      A ball valve is no good for a water brake. You need a valve that very gradually opens the flow, see https://yourdyno.com/YourDynoHelp/water-brakes/
      I always help my customers get up to speed, so don’t be afraid to ask more.
