Setting up WB in the ADX editor.

[POZE]

It's location is 2E8
Thanks

[RobertISaar]

which bit of the byte?

[EagleMark]

I think he found a mistake in the XDF!

Just leave it the way it does not effect it for now.

[POZE]

The parameter summary list shows hex n/a. What else can I do to find that info?

[POZE]

Only fan I have.

[RobertISaar]

since it's a flag, should be able to edit the flag(press F2) to see which bit it is controlling. or select it and watch the bottom of the screen, should see a "mask" value, that's the representation of the bit.

[EagleMark]

which bit of the byte?

0x2E8 bit 4 0x10

Only fan I have.

See if it works without? It may be wrong?

[RobertISaar]

huh.... that bit is used 9 times in the code.... doesn't appear to effect only fan control capabilities.

what pin is the fan controlled by? i could eliminate all of the other items it modifies and only leave it as fan control.

[POZE]

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.

[POZE]

C - 1 for the relay control of the fan. That is what pin 87 camaro uses along with the 165 ECM

[RobertISaar]

good, that means i can reference the 6E hack to see what hardware register controls it.

this shouldn't take too long...

[RobertISaar]

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?

[POZE]

It runs better with the box not checked. Fan disabled.

[RobertISaar]

okay, hopefully the last thing i'll have to ask:

can you post the exact BIN you're running now, so that i can patch it?

[POZE]

This is the current BIN
