even the factory tools wont do that but most give you the option to change the vin so you can fit a used one...

 I have read all the post regarding the airbag crash data reset, and that we are on the same page

          Don't think erasing the crash event in SRS will start the car for models like Witsend's example of BMW as that becomes a power distribution issue. Recently was able to clear crash code in Volkswagon and not sure which manufacturer I think some can be reset 2-3 times like the old days. There's plenty of companies that do the flash and are reasonable compared to replacement. On the downside you have to get it to them quickly not to hold up the job and sometimes it's a considerable amount of labor needed early on in the job. The manufacturers that lock up the ECU really want you to replace the unit which isn't that big a deal on some like Honda that come ready to install but others like Ford come empty and require programming to work right out of the box. The plus side of having sublet erase unit is all information is ready to go with no programming. Not that concerned about monitoring crashes with ECU as most replacements get done with insurance and it's already documented IE:Carfax. Not sure if all SRS units can erase eeprom  through the OBD connector or require board work. If Autel did it probably be the one's done at the connector using their server which may be a legal issue for them.
