Rolling Road Tuning at CAT Automotive in Norwich
It measures the torque applied at the wheels on a wide open throttle run. From this, power is calculated to give you a power and torque curve. This can be shown at the wheels or the calculated at the flywheel numbers. The dyno measures the rundown losses and adds this measurement to the measured power at the wheels.Our rolling road enables us to test your car in real world conditions as close as possible to driving on the road whilst monitoring the fuelling with wideband lambda readers, ignition systems with oscilloscopes, knock detection with formula knock detection along with turbo boost and much more including compensation for air temperature and barometric pressure.Rolling Road Remapping Norwich

With over thirty years’ experience and constant research and development Clive Atthowe Tuning has some of the most sophisticated diagnostic and testing equipment in the UK, including one of only a handful of four wheel drive rolling roads in the country housed in a bespoke air flowed soundproof cell this give us the edge over open rolling road constructions with air temperatures held at sensible levels whatever the vehicle being tested. We can rolling road test and tune two and four wheel drive vehicles up to 1500 bhp giving accurate repeatable results of bhp and torque.

Please don’t confuse our rolling road with the normal rolling road set up we are using the latest sate of the art software and control systems designed specifically by Dastek and has taken considerable time to research and develop this gives us complete control over the rolling road no matter what vehicle we are testing giving controlled repeatable results.
