Trying to repair the ECU on one of my cars, the ECU is water damaged and I can't repair it (Multi layer tracks gone and main connections)
I can buy a replacement ECU, but I need to hex edit the next ECU to contain the information of some modules, mainly the Immobiliser,
The keys are stored in the Immobiliser so all is fine there.
I am trying to read the serial EPROM however it a Fairchild device, 8 pin SOIC package with the following markings: B02AF which brings up bugger all on google apart from some sales listings in China,
I have tried most 93C devices but it's reading it as all 0000's.
The programmer I am using is a MiniPRO TL866A (Genuine Version)
Can someone ID this flash chip, or have an idea how I can find out what it is or what other chip types I can try.
