So If I have a 2008 E38 with OS 12624402 could I use 2010 OS 12647991 thus giving me twice the range in the IFR table?

If the OSs are in the same column, then you *should* be ok using another one of the OSs in that ECM with a Tis2Web flash.
If the OSs are NOT in the same column, you have a very high chance of bricking the ECM when flashing a different OS in. Tis2Web will NOT warn you either.

2013 Sonic RS Manual - 1.4L I4T E78, tuned, turbo mods, etc.
2008 TrailBlazer SS 3SS AWD Summit White - LS2 E67/T42, bolt ons, suspension, etc.
2002 Chevy TrailBlazer LT 4X4 Summit White - 4.2L I6 P10, lifted, wheels, etc.
I finally bricked my first e38 doing just that, changing os which efi warns you not to do, lol.
Is there a list anywhere of what is changed in each OS for a certain year?
You know we used to block the bypass option so you could not full flash if there was a mismatch, but people complained
I no longer monitor the forum, please either post your question or create a support ticket.
I probably was one of the people who complained, lol. It was 110% my fault, I definitely dont blame EFI. I knew the risks and ignored the warnings but I was willing to gamble the e38 ecm and I lost. All the warnings saying not to do it made me want to try it, kinda like telling a little kid no.You know we used to block the bypass option so you could not full flash if there was a mismatch, but people complained
