EEPROM Checksum question.

Postby Lunatic » Thu Sep 23, 2021 1:32 pm

Simple question for the more knowledgeable people here.

I have an EDC16U34. I wish to change VIN, mileage and reset the flash counter. Easy enough.
Now, is there a free tool/utility/program that can calculate the checksum for the ST95320 EEPROM?

Follow up:
1) Do I even need to correct the checksum? Or does it even matter on this EEPROM?
2) Can the checksum be calculated manually?

If you have information that can help me, I'd be very grateful. If you'd like to keep this on the down low, then send me a private message.

PS-I'm fairly new and still searching.

Thanks to all and have a great day.
