Hyundai Genesis - 93c66 - Mileage Edit

[sitnprdy]

Hello World

I've been studying the forum and have taught myself on how to edit the Mileage on my Hyundai Genesis, or so I though.

The Cluster is equipped with a
93c66 - NANO Micro Mini 93C66 EEPROM Chip

The tool I'm using to read the EEPROM is a
MSOP8 Pogo PIN Adapter

Software is
NeoProgrammer

Here's where it all begins

The first EEPROM read I did was with an Xtool x100 pro2
I was able to get this .bin file (0OG.bin)
Aprox Mileage on the read being 89900 +- KM

When I edited the file to be 74600 +- KM
I could not write to the EEPROM using the Xtool x100 pro2

This is when I got myself a CH341A Programmer and Jumper Wires
this is the diagram I followed to connect a 93cXX to the CH341A

I was now able to write to the EEPROM and was able to Read the File to confirm that I was written to it.

Although when I connect it back into the vehicle the display is blank.

Some help would be greatly appreciated.
