No. A dynamometer is only as accurate as its software and measuring system. A dreamscience Dynamometer is a very accurate dynamometer with a controller that is far superior to any hub-type dyno on the market. dreamscience offers a control logic/mechanical design package that is unmatched in the industry, including a highly accurate load cell for measuring torque. For this reason we are able to offer features like road-load simulation, which no hub-type dyno can offer. Hub-type dynos are merely engine dynos coupled to your hubs, and engine dynos offer only the most elementary of controller capabilities.
