Dynamometer instrumentation kit

YourDyno is a dynamometer instrumentation kit that includes all you need for dyno data acquisition and brake control:


  • Data acquisition electronics box with USB interface
  • Supports inertia dynos, roller based dynos with 1 brake or 2 brakes (4WD or dual brake on one axel), and hub dynos with 2 brakes (2WD)
  • A setup with 2 boxes supports 4WD hub dynos (4 brakes, 4 load cells and 4 RPM sensors). 
  • All brake outputs use individual brake controllers (i.e. supports setups with different brakes and different load on front and rear axel)
  • 1 k-type thermocouple input (for engine or exhaust temperature). Can add up to 8 more thermocouples using the CAN Tool plugin
  • 3 analog (0V-5V) inputs, for example for Lambda sensors, MAP, boost, etc. Can add more analog channels using the VM167 plugin
  • 2 RPM inputs
  • 2 Brake control outputs, each supporting either Pulse width modulation (PWM) and analog  (0-5V) signals. 1 output supporting Stepper motor
  • Self powered from the USB cable, no external power supply
  • Supports any analog load cell for brake/absorption dynos. Specify max load when ordering or use your own load cell(s)
  • YourDyno sells a hall-effect sensor for easy RPM measurements with 3.5m shielded cable. Any digital 0-5V sensor can be used (also encoders). VR sensors are not directly supported, but can be used with an interface board such that it provides a 0-5V digital signal. 
  • Horsepower correction factor using to SAE J1349 (based on temperature, ambient pressure and humidity from manual entry or from environmental sensors (included)
  • Support for OBD2 adapters (bluetooth or USB) in the ELM327 series. Here is a recommended OBD2 adapter: OBDLink® LX
  • Support for USB CAN bus adapters to read CAN sensors and ECU data. Here is a recommended CAN bus adapter: Canalyst-ii
  • Support for KMTronic external relays, controlled by buttons or by data channels being over or under a threshold. Use this to for example automatically turn on a fan. 
  • Easy to use FREE PC software with setup wizards and calibration options
  • Software supports a plugin system that enables endless opportunities for integrating other sensors. See our plugin library

A number of Dyno manufacturers run YourDyno, among them dynoKRAFT. In addition hundreds of dynos get their dynamometer instrumentation kit upgraded to YourDyno every year. Take a look the YourDyno reference page and at our YouTube channel, or check out these videos to see YourDyno in action:

Selecting the right load cell

Calculate the right load cell size here:




  • Very accurate 16 bit AD converter (65536 different measurement levels)
  • Fast data acquisition (>100Hz) on all channels
  • RPM resolution: 42 nano second
  • Supports any load cell (specify 20, 50, 100, 200, 500, 750, 1000, 1500 or 2000 kg at checkout or use your own)
  • Controls up to two independent brakes using either:
    • YourDyno Eddy Current Power Supply
    • Analog voltage control (0-5V),
    • Pulse Width Modulation
  • Can control 1 brake using:
    • Stepper motor
  • Connector for K-type thermocouple for exhaust or engine temperature logging. To log temperature, buy a suitable isolated thermocouple for example on eBay (search for EGT K-Type thermocouple)
  • 3 Auxiliary sensor inputs (0V-5V analog interface). See instructions on how to connect aux sensors here. Aux inputs can be used for for example Lambda monitoring, boost, temperature, etc.
  • Environmental sensors for automatic horsepower correction based on standard correction factors (SAE J1389, DIN 70020, ISO1585, STD J607, etc)
    • Ambient temperature sensor absolute accuracy: 0.5 ºC
    • Humidity sensor absolute accuracy: +/-3% relative humidity
    • Ambient pressure sensor absolute accuracy: +/-1hPa (equivalent to the ambient pressure difference of ca +/-10 meter vertical distance)
  • Support for 2 RPM sensors, 2 brakes and 2 load cells
  • 2 YourDyno boxes can work in tandem to support 4 RPM sensors, 4 brakes and 4 load cells (4WD hub dyno typically)
  • Supports sensor plugins and brake control plugins for expansion of functionality
  • OBD connection and logging
  • Easy calibration
