Interesting process - thanks for sharing. Looking at the old module in the close up mode there appeared to be a cold solder joint and corrosion slightly to the left and upwards of the 8 pin chip - just an observation.
Thanks for another valuable video. Is this applicable to say a 2018 Camaro? I had ran into one this year that I could not clone. I have been using obdstar dc706 but it could not extract the flash and eeprom from it due to some internal damage. It could from the donor ecu but not for the original ecu
It depends on the design of the ECU. If the design team used an eeprom then you would be able to clone the information. The only was to know is to open it and look.@@DFWAuto_Hack
Great tutorial! Nice that you are going over some basic stuff as well! Are there any truly LIVE humans at AR Labs? As opposed to DEAD humans? 😂 Cadillac Jack
Thanks. Regarding "live humans", the point is that unlike some "email/website" only businesses we have people that will answer your questions. We have had people call just to confirm that we're real and not a scam.
Checksums originated as a way to confirm that no changes have occured in program code, not eeprom data code. If a checksum calculation is done it will be done when the module (usually the ECU) first starts. A checksum is the sum of the bytes in a memory part. The result is stored, usually at the very top of memory. Once a checksum calculation is complete the program compares the result with the stored value. If they match then the program code is considered valid. ECU tuning would require a recalculation of a checksum. Not all modules use a checksum. The checksum is programmed with the module is fabricated, not on the assembly line.
With the thousands of modules in vehicles it's not possible to know if the design changed to a different storage technology. There is no point in changing a design if it works but that does not mean they don't do it.

It's possible. That may have been the reason for the module failure. Moisture and electronics do not mix.
Man welcome back
Thanks. As we're a small business things have been busy.

@@andromedaresearchlabs7826 EXACTLY why I commented. Wanted you to point that out. AR Labs has the BEST customer service ANYWHERE!
when do checksums come into play?

Are the chips the same for the newer ecus as well? I assume so but just curious. referencing 2020 eras.
