JHS Racing provide a comprehensive motorcycle engine performance dyno tuning & diagnostic service using our Dynojet rolling road facility.
We are an approved and fully authorised Dynojet Power Commander motorcycle dyno tuning centre serving Bristol and the south west. Our technicians are fully trained and certified by Dynojet UK.
Using the most up to date Dynojet 250i dyno in our air-conditioned facility we can dyno test motorbikes up to 500bhp.
In combination with the very latest tuning link software we can supply and install the Dynojet Power Commander engine management and quickshift unit for many motorcycles. These units enable us to accurately set up the fuelling and ignition to achieve optimum performance. In some circumstances we can also make mapping adjustments directly into the ECU.
Direct ECU fuel mapping/re-flashing
is now a very popular option. Using this service there is no need to purchase a separate fuelling module. We can access your ECU internally and make changes to its programming, which is sometimes known as ‘re-flashing’. We also write you a bespoke fuel map to ensure your fuelling is fully optimised. Software and features vary for different makes and models of machines. For example the Kawasaki ZX10r 2016/17 model – we are able to: Enable the auto-blip function, adjust RPM limiters, adjust fan temp, adjust RPM idle – just to name a few.
Please call for more information for your machine 0117 986 8844
Direct ECU mapping is available from £399
Dynojet’s Load Control System uses the latest in eddy current power absorption technology which, combined with Dynojet software, enables our technicians to achieve consistent, repeatable results.
