Hello everyone,
through my internet research i came upon a post with you mentioning that you've done some work on odometer reprograming.
I am currently in the process of doing that to overcome the dreadfull toyota matrix 299.999km stop, I have desoldered the old eeprom (93C46),
I have a couple of empty 93C46 chips that i want to copy the contents of the original and modify it and replace it, im doing so because the old chip is brittle and i dont wish to use it
It should be noted that the old chip is ST 93C46W(x) last character is scratched, and the new chip is AT93C46
I used an old Windows XP system and a diy serial interface with ponyprog software to communicate with the chip and was able to save the dump and decode the reading and what needs to be modified
The problem began when i attempted to write onto the new chips and kept getting a write failed error, and due to my limited knowledge in the field i decided that its time to get a propper eeprom reader and writer and i got myself a cheap CH341A, but there was no propper documentation on how to use it and what software to use for that programmer and this is where i am right now
If any of you can please point me to the right path or give me any guidance that could help me get this job done asap i would really appreciate it
Thank you
