A dyno that is coupled directly to an engine is known as an engine dyno. A dyno that can measure torque and power delivered by the power train of a vehicle directly from the drive wheel or wheels without removing the engine from the frame of the vehicle), is known as a chassis dyno.
A host of functions required for ECU software calibration, such as interface-dependent calibration methods, calibration data management, measurement data visualization and analysis, ECU programming, vehicle bus monitoring, as well as remote control through standard interfaces, are part of the product's functional complement.
LS-DYNA originated from the 3D FEA program DYNA3D, developed by Dr. John O. Hallquist at Lawrence Livermore National Laboratory (LLNL) in 1976. [4] DYNA3D was created in order to simulate the impact of the Full Fuzing Option (FUFO) or "Dial-a-yield" nuclear bomb for low altitude release (impact velocity of ~ 40 m/s).
The software is based on the stochastic reactor model (SRM), [17] which is stated in terms of a weighted stochastic particle ensemble. SRM is particular useful in the context of engine modelling [18] as the dynamics of the particle ensemble includes detailed chemical kinetics whilst accounting for inhomogeneity in composition and temperature space arising from on-going fuel injection, heat ...
The Open Dynamics Engine (ODE) is a physics engine written in C/C++. Its two main components are a rigid body dynamics simulation engine and a collision detection engine. [ 3 ] It is free software licensed both under the BSD license and the LGPL .

Modern electronic control units can be tuned by simply updating their software through a standard interface, such as On Board Diagnostics. This procedure is commonly referred to as engine or electronic control unit tuning. Electronic control units are a relatively recent addition to the automobile, having first appeared in the late 1970s.
A chassis dynamometer, informally referred to as a rolling road [1] or a dyno, is a mechanical device that uses one or more fixed roller assemblies to simulate different road conditions within a controlled environment, and is used for a wide variety of vehicle testing and development purposes.
