You cannot gain access to anything that is not actually been mapped...........and I can tell you its not mapped by EFI-LIVE
So even if the EPA stops enforcement and the emissions standards are repealed, etc............IMHO, they are not going back into the binary and mapping these missing items out.
You will need to find it for yourself or find somebody who can do it and pay them for their expertise
