Will try ...

All my hopes to reflash my ECU are broken. The "flash" used in my ECU is nothing else as EPROM. Datasheet is M27C512. My chip has no window to erase even. Chip located nearly eeprom has no deal to it. 'cause main board design is 3 layer I had mistaked :oops: One people geve me idea to see ...

I see it not essentially differ form ZXJN. I had seen that memcal it was used for euro-0 daewoo 1.5 8V. But I be mistaken.

Yes, mode 2 is supported

I have found datasheet which wery similar to my ECU flash controller. The chip is called: PSD8XXFX Flash in-system programmable (ISP) peripherals for 8-bit MCUs, 5 V From datasheet, I see that ports B and F are connected to proper PSD8XXFX address pins. Could someone look at this controller and says...

The big problem I couldnt identify the chip DELPHI 466 which connect flash memory to MCU. No datasheet was found

As it connected to external bus there should be flash registers to handle flash controller in memory space. Could someone help to identify the chip?

I found two entries where aldl commands received. The first one is wery simple, it process two modes: 0x05 and 0x06. Look at 0xD8BD in attached file. It is exactly what I need. Mode 0x06 loads into memory user code and jump to subroutine at addres wich specified in first two bytes of aldl packet imm...

I have started disassembling. The main gpoal is to have full aldl info about modes.

I will report progress

The archive with few pics of my ECU

I couldnt attach file up to 16Mb. Will try by photo
