Jetskiworld.gr has been testing a new reprogrammable ECU mapping specifically designed for the Kawasaki Ultra 310R for Offshore/Endurance racing. The first tests showed positive results with an increase in top speed by 2km/h and a stronger punch of acceleration in mid rpms. Actually the engine was responding better from upper low to mid rpms and progressively was getting linear to top rpms. A complete report will follow soon.
