This mode allows you to retrieve the original file from the database by connecting directly to the ECU connector, without opening it: a useful option when the ECU has already been removed from the vehicle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The new modes complement the OBD connection in Virtual Reading mode already available, giving workshops greater flexibility when working on the latest-generation Yamaha 125 scooters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Real benefits for your workshop:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>New BENCH and BOOT connections for Yamaha N-Max 125 and X-Max 125<\/li>\n\n\n\n<li>Full ECU reading and writing in BOOT mode<\/li>\n\n\n\n<li>Virtual Reading mode in BENCH and OBD<\/li>\n\n\n\n<li>Support for 2021 models (B6Y and BMJ) and 2025 models (BPB)<\/li>\n\n\n\n<li>Multiple access modes for greater operational flexibility on RH850 HWII family ECUs<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">With KESS3, workshops can expand their tuning and repair services for the scooter segment, using different connection modes according to the requirements of each operation.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Technical focus<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Connection: <strong>BENCH, BOOT<\/strong><\/li>\n\n\n\n<li>ECU: <strong>Denso XXX-H594A-XX<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Denso B6Y-H594A-20<\/strong><\/li>\n\n\n\n<li><strong>Denso BPB-H594A-00<\/strong><\/li>\n\n\n\n<li><strong>Denso BMJ-H594A-00<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Production years: <strong>from 2025<\/strong><\/li>\n\n\n\n<li>Brands involved: <strong>Yamaha<\/strong><\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Supported vehicles<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Yamaha N-Max, X-Max 125<\/strong><\/p>","protected":false},"excerpt":{"rendered":"<p>Two new access modes for Yamaha N-Max and X-Max 125 scooters with KESS3.<\/p>","protected":false},"author":45,"featured_media":11576,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[99],"tags":[],"class_list":["post-11586","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-alientech"],"acf":[],"_links":{"self":[{"href":"https:\/\/ecuremapcenter.com\/de\/wp-json\/wp\/v2\/posts\/11586","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ecuremapcenter.com\/de\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ecuremapcenter.com\/de\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ecuremapcenter.com\/de\/wp-json\/wp\/v2\/users\/45"}],"replies":[{"embeddable":true,"href":"https:\/\/ecuremapcenter.com\/de\/wp-json\/wp\/v2\/comments?post=11586"}],"version-history":[{"count":1,"href":"https:\/\/ecuremapcenter.com\/de\/wp-json\/wp\/v2\/posts\/11586\/revisions"}],"predecessor-version":[{"id":11587,"href":"https:\/\/ecuremapcenter.com\/de\/wp-json\/wp\/v2\/posts\/11586\/revisions\/11587"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ecuremapcenter.com\/de\/wp-json\/wp\/v2\/media\/11576"}],"wp:attachment":[{"href":"https:\/\/ecuremapcenter.com\/de\/wp-json\/wp\/v2\/media?parent=11586"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ecuremapcenter.com\/de\/wp-json\/wp\/v2\/categories?post=11586"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ecuremapcenter.com\/de\/wp-json\/wp\/v2\/tags?post=11586"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
