    Attached is a .bin (SBC 383 Holley TBI) that I set up including WBO2.

    Open up the hex editor in Tuner Pro (ctrl+h IIRC), go to the addresses needed and type the HEX values into the locations indicated in the first post. Once you get through the values, click on save or commit to bin, save under a new file name, and continue as usual.

    You can add the parameters to the XDF as well, so that you can make adjustments, if there isn't already a posted XDF with the fan parameters in it.
    it wouldn't take much more effort than doing it once to make it as a patch XDF item.... then it would be a 2-click operation for anybody to add in or remove.

    Is patching enabled in Tuner Pro now?

    Yes! Take a look at the latest $42, I used the Patch to do Highway Lean Cruise, ESC Done test and EGR disable. Works sweet!

    Cool, I'll have to learn how to make these patch executables, for a couple patches I have found. :)

    i don't know if the executables work or not, but as an XDF item, they work great.

    Ok, I guess I'm missing something on this then...

    AFAIK, there are two patching "methods", one via S-Record and is done through the File menu(which i've never gotten to work correctly, probably my own lack of understanding/experience with it), the other is creating a new item in the parameter tree.

    How would creating a new item in the parameter tree be any easier than manually editing the bin via HEX?

    --==EDIT==--

    I just looked at Mark's $42 XDF and I would call that a patch executable...

    I see how that would be easy to use.

    S record has never worked. I tried to get Mark M help and he told me the S record patch I had, had hex address outside of the chip range... but it did not? I used it to make the Patch and it worked fine.

    Just looked at first post and a patch would not be hard? In the zip folder is all parameters needed to make changes, these could be added to a folder in regular $0D XDF to simplify.

    There is one instruction at end of Hex changes that I could not find in the detailed instructions? What does CBB0: 7E 70 71 do? There is no instruction on CBB0 ?

    IIRC, those 3 values are what allow the fan code to actually operate. I recall in a different set of instructions that a change outside the large block of HEX values needed to be made to enable the fan controil to work, I don't recall if it was that address or not.

    Well my insomnia is in full swing... so I added all the E Fan Parameters from the E fan XDF to my $0D xdf in a "E Fan Control" folder and also a patch, but have not worked on the patch yet.

    This $0D XDF has everything the the original did, just re-orginized, compacted and simplified for easier use...

    Maybe if I get some sleep tonight I will be coherent enough to write the patch...

    Hmmm?

    This all looks OK and documented:
    Hex Editor Values:
    00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

    7060: 08 B6 01 50 D6 02 C4 F0 26 04 4A B7 01 50 4F 5F
    7070: 39 12 52 08 08 CE 70 00 FF 3F D4 20 44 FC 3F D4
    7080: 1A 83 77 FF 23 02 22 14 CE 77 FF FF 3F D4 FE 01

    70F0: 15 46 04 7E CB 3A 00 00 00 00 00 00 00 00 00 00


    Then maybe this is what your talking about?

    7C60: BD 70
    7C70: 19

    CAF0: 7E 70
    CB00: C4

    CBB0: 7E 70 71

    Because it does not match:
    To Enable TransmissionFan Routine:
    L400B Bit 1 AIR Management= 1
    Change hex editor values starting at CAFE, from 96 06 B1 to 7E 70 C4.
    LCAFE ; 96 06 ; LDAA L0006 ; Cool temp, linear
    ; B1 4E 82 ; CMPA L4E82 ; Min temp for AIR
    LCAFE ; 7E 70 C4 ; JMP L70C4 ; Jump to transmission fan routine

    You asked about the values at CBB0, which IIRC enable fan control, ENGINE fan control. The E-fan patch I used did not have any transmission fan control settings.

    The .bin file I attached in post 106 also has 700R4 TCC enabled.
