Hello m8,
Thank you for advice, it is helpfull, you made good job.

here is crc solution I calculate for 140000 and 108000 and both work.

org 203026km crc 8405
0km crc 83EB

143000 HEX= 00022E98 xor FFFFFFFF = FFFDD167 STR1 crc 867D
108000 HEX= 0001A5E0 xor FFFFFFFF = FFFE5A1F STR1

203026/100 = 2030 hex=000007EE XOR 8405 = 83EB = 0km crc

143000/100 = 1430 hex= 00000596 XOR 83EB = 867D = crc OK
108000/100 = 1080 HEX= 00000438 XOR 83EB = 87D3 = CRC OK
