I think he found a mistake in the XDF!
Just leave it the way it does not effect it for now.
1990 Chevy Suburban 5.7L Auto ECM 1227747 $42!
1998 Chevy Silverado 5.7L Vortec 0411 Swap to RoadRunner!

The parameter summary list shows hex n/a. What else can I do to find that info?
Only fan I have.
It did not work w/o the flag set if I understand your question. Also have to adjust the Fan Disable Speed and Fan Enable Speed to 0 MPH to get the fan to operate. I will check the pin location.
C - 1 for the relay control of the fan. That is what pin 87 camaro uses along with the 165 ECM

looks like 4004, bit 1 is what controls that output.
also, it appears that the "total async pw" value that gets transmitted in the datastream may be wrong... GM goofed the documentation, so what actually gets output there, i have no idea.
upon further inspection.... that bit actually controls whether the ECM thinks you're playing with a 2.5 lumina or a 2.5 S10... so it does certainly control more than just the fan. the W-bodies used electric fans among a few other things that were different compared to the S10. oddly enough, the W-body used the 1227727 ECM, not the 1227165... so this program may or may not work in that as well. weird.
3 of the 9 locations have to deal with the fan programming, so i'll have to disable the other six. does the engine run better with the bit set or cleared?
It runs better with the box not checked. Fan disabled.
This is the current BIN
