The R&D Speed Control Module installs and interfaces between the stock speedometer and the O.E.M. ECU and works to cancel out all top speed reduction manipulations from the ECU. Without the R&D Module, the ECU can regulate the throttle plate to lower air flow volumes, and boost levels into the intake manifold plenum, which in result restricts top speed performance. The R&D Speed-UP Module allows full boost levels to be achieved which produce a 4-5 MPH speed gain on a box stock Ultra 310X. The R&D Module will allow all aftermarket bolt-on parts to perform to their full potential. The R&D Module interface is completely undetected (stealth) to the ECU which means no dash warnings, codes, or stored information to worry about. The R&D Module plugs into the O.E.M. wire harness super easy in 5-10 minutes. A plug and play speed gain in less than 10 minutes! No tools required to install. NOTE: The O.E.M. Kawasaki dash display is only internally capable of displaying peak top speeds to 67 MPH, so, rely on GPS devices to check peak top speeds, OR, rely on the RPM/Speed chart information in the installation instructions that will give you RPM to Top Speed references!
