电动车中一线通SIF数据中的数据解码，求大神看看，这里怎么哪个是速度？
我用stc32g做了一个电动车仪表，想把时速显示上去,又网上买了一个支持一线通的电动车控制器，数据已经解调出来了，但是好像它这个数据进行过二次加密或校验，不知道那个地方是显示车速的，。
一共是12个数据，数据解码应该是没有问题，我是用逻辑分析仪抓包手动解码过，而且在其它电动车上解码得到过检证，只是这款控制器进行了二次加密或校验，求大神指指路，我想提取速度值。
第一个为标头，最后一个为异或检验，中间的第七位0x00是一直没有变化，第二位也会隔两位增加一次，而第三位就是整数增加，后四位始终是0，开始是从0x00,再到0x10,再就是0x20,这样加上去，第八位和第九位，在电机没有启动的情况下是一样的，一但启动就会有55的差，用后面的数减前面的数，第十一位减十位，总是保持35的差，求大神分析一下！
补充一下采集数据，这是在不同转速下的数据
