Due to the diagnostic experience at JKM, along with our specialist in house equipment JKM offer a host of unique fault diagnosis services performed on our Dynamometer. For example :
The ability to drive a vehicle in any simulated road scenario up to 150MPH whilst having most workshop 'only' diagnostic equipment simultaneously connected to the vehicle.
Accurately measure the Air to Fuel ratio of any engine whilst being held at any load condition using our precision high speed wide band O2 sensor.
The ability to visualize a fault (For example a turbo pipe leak) on the engine under investigation.
JKM are happy to offer 'rolling road day' events for most road car groups & clubs. We have ample secure parking on our premises and we also provide FREE tea, coffee and biscuits for most rolling road day events. We ask for a minimum of 10 cars, the maximum per day will vary depending on the type(s) of car.

On Dyno days we run with the Dynamometer configured in 'ShootOut' mode for consistent and comparable results (with other Dyno Dynamics Rolling Roads).

JKM have put together a Technical artical on the 'Rolling road' process, to try and explain more about what happens when your car is tested, and where 'errors' can creep into the process.
