这是我们这里的水卡，我们这里水卡是每天更新的，每天定点更新，水卡是60L的，就是到了晚上某个点，就算你昨天用光了，也会重新有60L的热水，楼主现在已经研究好几天了，已到瓶颈，求突破~

我分析了下这俩个数据，这是2组数据，扇区10和扇区11的数据对比，对应是60L和30L水量的对比（左边60L，右边30L），意思是就算水量使用后，（从60升用到30L，扇区10，扇区11数据都是没有任何改变的，我试了好多组也是这样不止60-30L，但是我觉得这里应该这里有限位数据？我改到60L往上就会刷卡错误。）这是2组数据，扇区10和扇区11的数据对比，对应是60L和30L水量的对比（左边60L，右边30L），意思是就算水量使用后，（从60升用到30L，扇区10，扇区11数据都是没有任何改变的，我试了好多组也是这样不止60-30L，但是我觉得这里应该这里有限位数据？我改到60L往上就会刷卡错误。），求赐教~

我对60L到0L做了一次完整的刷卡记录并提取了数据。
这是我对扇区15做出的分析，是水卡从60L一直到0L的所有分析，经过对比发现，扇区15的第0块和第2块是一致的，而且每次变的只有第①节（1），第⑦节（7），第⑧节（8，其中这一节只有开始2次数据是17，其他时候数据都是18，不变），和第⑯节（16），也发现了一点规律，但是后面根据这些规律修改数据还是会出现读卡错误。
最后还是没能修改到60L以上，一修改超过60L就报读卡错误，求大神不吝赐教~~

除上面这些之外，楼主还找到了以下规律，各位大佬帮忙看看，数据都是从16进制转到10进制以后的数据。
（以下都是15扇区，第0块或第2块的数据对比，这两层数据每一组数据都一 一对应的，即每组数据都不一样，但是对应同组的数据第0块和第2块是一样的）
规律①：第一节，每隔一组数据都是等差序列递增的（除了第一组），例如当水量是59，57，55时数据则为24，26，28，当水量是58，56，54时数据则为：27，29，31······等差值为2；（转十进制后）
规律②：第七节，每组数据都是等差序列递增的（除了第一组），例如当水量是59，58，57时数据则为：1，2，3······等差值为1；（转十进制后）
规律③：第8节，每组数据都是一致的，数值为18，（除了第一组，第一组数据为17）；（转十进制后）
规律④：第16节，每组数据都是等差序列递减的，例如当水量是59，58，57，56时数据则为：232，231，230·······等差值为1；（转十进制后）
规律⑤：每一组数据对应符合以下公式，⑦＋⑧-⑩-⑪=⑭-⑯（7＋8-11-12=14-16圈内数字代表对应的节数）；（转十进制后）
规律⑥：每一组数据对应符合以下公式，⑦＋⑧＋⑯=256；（7＋8+16=256）（转十进制后）
规律⑦：每一组数据对应符合以下公式，⑥+⑦+⑧+⑩+⑪+⑭+⑯=767，（6+7+8+10+11+14+16=767，圈内数字代表对应的节数）；（转十进制后）
我看别的教程说这些规律是用于效验码的计算的，也不知道有没有用，但是发现每一组数据都符合以上规律。

这是我昨天对扇区10-11的数据分析，图片下面已转成10进制，但是没看出来啥特点，求高手指教，是不是这里有数据限制，所以编辑不了60升以上的水量，一编辑超过60L就显示读卡错误。
大神们帮忙看看应该修改哪些数据可以使水卡突破60L以上，球球了，已经到知识瓶颈了。

尝试了一下修改数据，结果还是无法识别，求分析。
我感觉这里，每一个节的计算我都没有出错的，感觉就是扇区10，扇区11有限位，所以导致修改数据也不行，大神们帮忙看看~求突破~

看数据了 感觉是联网的 ，数据都像是刷卡记录，有两个思路，1是修改限定值（60），2是修改变化的数据 ，假设15扇区的E8是代表60L来算（因为它是递减），用FF-E8=17这算法来改，把E8 17 改成 F8 07 试试

@倔强的乔治👹 应该不是联网的，因为我们这水卡是不收费的，另外我可以无限复制卡，我主要想改数据改高点，而不用每天重复写卡，你说的数据我等下试试，最好你写一整个块0的数据出来，我复制上去试试呗，因为我怕我计算有误，如果多个人罗列出来的数据，进行对比没错的话，那就稳妥了。
