Hi all, need a bit of assistance if possible.
Im trying to disable the immo on the MSA 12, the immo data is held on an SOIC8 chip which I removed from the board and inserted into an SOIC8 to DIO8 adapter on the GQ-4x4 programmer.
I add device 93C46, successfully, I can read successfully, I alter the file in hex editor, erase the chip but when I try to wrtie the new or amended file I get write but then verify fails. Being EEPROM I should be able to write multiple times.....Confused.
verify failed, address=0x00002C, Device=0x60, Buffer=0x00
Pin 17 on the image of the slot is red
Any help gratefully received |

blank check and IS not supported with chip type.
I had a successful write, i turned the adapter upside down and it wrote !
Still no comms to VCDS when ECU installed though and no start but the glow plug light now goes out.
I socketed the ECU and installed 28 pin DIPs with map files on |
