motorcycles and scooters manufactured from 2019 onwards and equipped with Keihin 38770-XXX-XXX ECUs. These are widely used models with engine displacements ranging from 125cc to 1100cc. <\/p><p>The new BENCH protocol lets you work directly through the ECU connector, without opening the unit, using the Virtual Reading function to access the original file. A useful option when the ECU has already been removed from the vehicle. <\/p><p>This new mode complements the already available OBD Virtual Reading and BOOT modes, allowing you to choose the most suitable connection method for each operation on supported Honda applications.<\/p><p>Real benefits for your workshop:<\/p><ul><li>Read using Virtual Reading, also through the ECU connector.<\/li><li>Three available operating modes: OBD Virtual Reading, BENCH VR and BOOT.<\/li><li>Extensive Honda coverage, from smaller-displacement models to more powerful motorcycles, from 2019 onwards.<\/li><\/ul><p>With KESS3, workshops working on scooters and motorcycles can carry out everything from tuning to repairs, using different connection modes according to the requirements of each operation.<\/p><\/div><\/div><\/div><\/div><\/div><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f987a08 elementor-widget elementor-widget-heading\"
