Hi guys, I found out I may have to alter the immobilizer in my ECU. It is a soic8 chip, but my adapter is in the mail from China and will probably not arrive for another month. Can I fabricate my own temporary clip with some copper wire plugged into my willem? Since the adapter seems like just a connection betweer the soic8 pins and the 8 larger holes on te board.
Anybody got some tips/do's/dont's?
Thanks!

Bootmode the contents of the chip off with argdubs tool.
This will avoid having to remove the chip all together.

Yup, it is for the old style 5 connector AEB ecu from '95. I misinformed myself about the immo, because the US versions don't have an immo on those AEB ecu's. I am using an Euro version though  Grin
I have read on several forums about making the clips, it seems you can make use of an old PCI slot modified as a clamp. For now I will just put wires on the pins however, and connect them straight into my DIP8 slot on the Willem PCB50 board. I will report back if it works or not  Roll Eyes

hmmmm well I just soldered 8 wires to the SOIC8 and plugged them into my willem dip8 24cxx slot.. When it is unplugged I get "hardware present", but when the wires are inserted I cant connect at all... I get message "No ACK device command" when trying to read or write, and in test mode I get "hardware error - check power and connection"

There are no connections between wires at visual inspection, but when measured I see pins 1-2-3-4 interconnected and pin 7 and 5 to 1,2,3,4. Is that normal or is the chip damaged? could be I heated it up too much on my first attempt of desoldering...?

My Willem is a pcb50b and according to the software all dip switches need to be at off. Which they are.
Anyone care to shine a light on here?

I have fixed the problem by unsoldering the chip. Connected straight away and no problems writing the new file  Smiley

Wow, thats a lot of work to flash that chip.

I bought a cheap 24c08 eeprom writer off ebay and it came with a nice board to solder the chip onto and it then fits into either that writer or my william.
