Dyno software for inertia dynos i n the race shop or at home The OnTrack dyno software can be used for any type of inertia dyno where the engine accelerates a mass such as a flywheel or heavy rollers. Many customers use OnTrack for their "home built" inertia dyno projects where they build a dyno frame with a motor driven flywheel or wheel driven rollers and use the software with a Speed Sensor triggered by a magnet on the flywheel/rollers. The speed sensor plugs directly into a PC or laptop sound card port
Dyno software for v ehicle acceleration dyno runs at the track
Vehicle acceleration type dyno runs use the same principle as a fixed inertia dyno. Instead of accelerating a heavy inertia flywheel or rollers, the engine is dyno tested by accelerating the total weight of the vehicle. To measure the vehicle acceleration OnTrack can use data signals from either the vehicle speed or engine rpm. For example you can use an Ignition Sensor that clips onto a spark plug lead to pickup engine rpm, or use a Speed Sensor triggered by a magnet to pickup vehicle speed, or use any of
