Hi all, I have a true GQ4x4 and have removed the SOC8 chip from an ECU 074 906 021S which is 24C02 and installed it in the adapter and connected the adapter t the programer in the position farthest from the loc lever with the chip indicator dot facing the lever.
I select All generic 24C02 from the device list and then when I read it, it comes back with read complete on 0.7s and the buffer is filled with all FF.
If I do a blank check it comesback blank when it is not.
Any ideas please ?

This worked. Looks like the 24C02 is a 5V device,

@anniel - Thanks but how to use the information you posted - were do I put it - how do I configure it please ?
Thanks
Simply add the line to devices.txt or customdevices.txt.
In the menu > Device > User Folder.
Thanks but I checked the program files folder for the programmer and no such file exists - just .exe / .dll No sign of devices.txt
where do I find this file please ?

I tried this too and then managed to get a read that looks good but has too many rows.
I exect this is some sort of bug or driver problem facing the GQ 4X4 ?
Is there a way to change the file to be compatible with 24C02 ?
Thanks
Try with this:
Name="24C02 5V VCC",ID="XXXX",Class="24C02",Category="SERIAL_EPROM",MFG="ALL(Generic)",VCC="5V";
