Tried changing that address, no success. Baro stayed right where it was at (like 67 or something). Thought I was one to something. Maybe it has something to do with the "non volatile memory" - from the disassembly notes ? It's like the ECM is reading the value stored instead of writing what we want it to.

Also tried to just disable part of the patch. If I disabled either half of the patch, it did not update the Baro setting at key on, that surprised me. Disabled the whole patch, then it would update Baro to MAP of 55kPa. BUt upon driving, it would update Baro to something under boost eventually. Something in the high 60's running the tune rich.
