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 ?
