Yeah it's right, but you have to look at everything else as well. This is for your $85 but it's very similar to $42.
First has to reach enable temp (I added it to xdf) at 0x310
Then it has to meet three qualifiers:
MAP enter 0x308
MPH enter 0x306
RPM enter 0x304
After all those qualifiers are met and then TPS value falls below 0x30E then it will enter DFCO and still have a delay at 0x30C
It will stay in DFCO until any of the RPM, MAP or MPH Exits qualifiers are hit.
The comments in disassembly don't describe it that well...
