Guys. I hawe problem with this old ecu. IO Terminal read flash OK, but can't write back, only emulated eeprom write OK. So, im read flash 29F200BB by willem, frend make dtc off, calculate CRC, and when im write back, ECU is death, no communicate. If im write back org flash, all is OK, ECU back to life. Please, someone check crc in flash file after mod. Im upload three file: one flash read by IO Terminal (K-Line)and two flash read by willem /org and mod (winOLS)/.
Attention!
File read by IO Terminal ussing k-line are different to file read by willem.
Thanx for any help.
