Read/write as 16 bit if:
- The pin 6 (ORG) is connected to pin 8 (VCC).
- The pin 6 (ORG) is left unconnected.

Read/write as 8 bit if:
- The pin 6 (ORG) is connected to pin 5 (GND)

ok thanks for the info
its hard to know what the wires do on the circuitboard
all i know is its around a 2000 model toyota ls400

just stick it in the programmer and use the first chip option you show....

all you need a sop8 universal pin to pin adapter.....
it pretty simple......

:wavey:

im using GQ-4x universal programmer
and ive got a cable to a 3m chip clip
but i cant tell if im getting a good read

its not my ecu its a loan one from a shop so i dont want to unsolder chip

you have a very good programmer m8!
but as far as i know you cant read it this type of chip inboard with a clip...only 24c02 can be read inboard.....

you need a pin to pin universal adapter......

and yes!
the first chip type is fine......

you must desolger!

ok thanks
i might leave this one then
ill try chase up another ecu for myself as a spare to learn on
i dont want to stuff up a properly working set

i have some new 93c56 chips so if i can find a 2000 model ls400 dump i can play with it and with the transponders im getting

so basically i need long legs to clip into the programmer and the other end to hook onto the legs of the 93c56 chip
im going to order this

thanks again

i just had a brainstorm
i will be buying the toyota key copier programmer
and in the kit u get the adapter so i wont have to buy one

Hi is easy; just connect your progrmmer and launch the software and select 93c56 and valid; is not necessairy to choose 8bit or 16bit

Thanks
I'm just worried about removing chips hehehe
I solder car wiring 8 hours a day so I have to learn to be delicate if I start removing chips

[NZBrakelathes]

Did you find a tool to read this chip without unsoldering?
I need to do the same read erase write etc
Can you help advise?

[bram380]

Xprog can read write 93cxxxx incircuit.
some times need to short x'tal on board.

[NZBrakelathes]

Ok? On eBay I don't see them with a clip type thing
Just circuit board type
Or am I totally wrong?
Never used anything like it so I really don't know

[bram380]

Use P*mona 5250:

Totally confused :s
