It will be an issue resulting from the call and arg at 0ef10.

First confirm how many args sub 87e99 really takes, then command SAD if required.

Can you try to explain for me how you made the dir file from the tunerpro definition file please? I would like to try another one and start a third comparison to try and find other subroutines that I cannot find similar between RZASA and EQE3. Maybe OMAE2 as I also have a Harley Davidson F150, So I can apply things and see what may work and what does not. Also, Can you please point me to a write up for making a spreadsheet type def file for BE from a DIR file please?

SAD806x will import XDF and export DIR files.
Its not perfect, but it helps a lot.
https://github.com/OpenEEC-Project/SAD806x

The basic process is;
Install SAD806x.
Open the target BIN.
Run the disassemble command.
Import the target XDF.
Run the disassemble command.
Export to DIR.
The DIR will need some clean up, that may include processing the DIR using a spreadsheet.

The RZASA dir I posted was derived from a DMR file not a XDF file, but don't let that stop you.

Maybe OMAE2 as I also have a Harley Davidson F150, So I can apply things and see what may work and what does not.

I don't have a DMR file by that name, but don't let that stop you.

First off you need to understand what a BE def looks like.

The help file has a section covering what is required in the def file.

Next look at some open def files, here's the GUFB one.

Because you listened previously, you will have kept your DIR tidy and the columns aligned.

Your DIR will have lots of commands for Scalars, Functions, Tables and Payloads.
Others commands may not end up in your DIR.

Scalars are parameters at ROM addresses. Typically Bits, Bytes, Words and Longs. They could also be small code hacks.
Functions are the two column parameter blocks at ROM addresses.
Tables are the multi column multi row parameter blocks at ROM addresses.
Payloads are Bits, Bytes, Words and Longs at Register and RAM addresses.

The basic process is;
Open a new excel workbook.
You want to get the content from your DIR into excel and break it up into Scalars, Functions, Tables and Payloads.
Scalars, Functions, Tables and Payloads want to end up on individual sheets. The rest of the DIR ends up being discarded.
I usually import the whole thing to a worksheet then break it up over multiple worksheets within excel.

Import the DIR into a sheet or copy and paste to the sheet.
Use excels text to column command to break up the DIR into columns with the command, address, name, sign, size, comment and characters.
The DIR will have characters such as " and #, set column breaks so they can be discarded.
All columns need to be formatted as text.
You may need to create an index column from the hex address using =hex2dec(0xaddress).
Sort your columns by DIR command and address.
Copy and paste S, F, T & P rows to clean worksheets.
Use excel functions to convert the DIR cells into cells for the DEF.
Start a clean DEF workbook or use an existing one as a starting point.
Ensure all worksheets are formatted as text.
Copy the DEF cells from your DIR workbook and paste as text to your DEF workbook.
Complete all the other entries in your DEF workbook, such as equations etc.

Do not use the clear contents command in your DEF workbook, BE has issues with it. Use backspace or delete.
Again, ensure the whole DEF workbook is formatted as text.

Wow. That is a bit more in depth than I thought it would be. LOL. Maybe it won't be as intimidating after I actually get started doing it. I was psyching myself out with the disassembly and I think I have picked it up fairly well so far. I know my DEF file still has a ton of mistakes, but I can at least pick up on some of them better now that I have been working with it more and more. And your, and JSA's, direction has been indispensable. Also all the others that chimed in to help for sure including Decipha. So thank all of you very much. I will give it a shot and see what kind of trouble I can get into. Thanks again.
Side note: have you had anymore time to look at my EQE3 dir file and spreadsheet? Just wondering how many more errors you have found. I will try and post an updated version of my DIR file and spreadsheet in a few minutes. Thanks
Also forgot to ask, How could I determine if a specific PCM has hardware available for things like pwm fan control or hi/low fan control, or other things of that nature? Also how could I tell if there are extra inputs available for extra sensors, like ethanol sensors and things like that? I know I have the hardware manual but I am having issues identifying exactly what everything is on the actual board. And can hardware be added to boards to make things available? I know on most of the PCMs I have, have a lot of blank spots for chips and other components. Thanks again

Here is the updated compare sheet and Dir file.

It's not difficult, just a process to work through.

I have spent a little time on it but nothing to report at the moment.
I'll update to the new one you posted and continue.

Also forgot to ask, How could I determine if a specific PCM has hardware available for things like pwm fan control or hi/low fan control, or other things of that nature?

If an OEM application has the features, then that PCM could be used to implement the features.

Also how could I tell if there are extra inputs available for extra sensors, like ethanol sensors and things like that?

Tracing the circuit traces on the circuit board of the PCM to harness pins. If the harness does not have a wire for the pin, then it may be possible to use it elsewhere.

I know I have the hardware manual but I am having issues identifying exactly what everything is on the actual board.

The later PCM's have chips that are not covered in the manuals or handbook. Both the manual and handbook predate the first 8065 box in the wild and stuff changed pretty quickly after they started shipping 8065 boxes.

And can hardware be added to boards to make things available? I know on most of the PCMs I have, have a lot of blank spots for chips and other components. Thanks again

Yes components can be added to complete circuits. The trick is to work out what the unused chip pin is for.

Substituting a PCM from a posh model with more features than you need is the easiest way to get spare IO for other purposes.

Ok, So if I am understanding correctly, if the vehicle did not have it then the PCM probably does not have the components to implement the feature. My 2003 Harley F150 with EKO2 PCM, for example, did not have electric fans, so it most likely does not have the hardware to implement the feature? But I could maybe steal the EGR output to make it happen? But then I would have to find another output for a high/low fan function if desired? I would have to look in the service pubs to see if anything else deleted was a pwm output to implement pwm fans. Or I may be able to add the components to make it work if I can find the components and have the necessary spaces free on the board? I am very interested in doing PCM controlled fans on my truck for sure, also my dads truck with the EQE3 pcm. I have a high low controller on my truck now but it doesn't control A/C pressure as well as I would like, and it does not turn off at speed to let the natural air flow cool the radiator either. I feel like the fan actually inhibits the cooling some at speed. I guess to sum it up I would like to add some modern features and make it all operate like it was factory equipped. I am very OCD/nit-picky about things like wiring and aftermarket components that do not integrate seamlessly.
Then after finding or adding components I would have to figure out how to add the needed code to make it function, is there a write up somewhere for adding extra code to factory code and recompiling the BIN file properly to make it all work?

For large production runs, that would usually be the case.
For small production runs, the hardware code from a large production run might be used as is and may have spare IO in place.

My 2003 Harley F150 with EKO2 PCM, for example, did not have electric fans, so it most likely does not have the hardware to implement the feature?

Does any other application using the same hardware code have electric fan control??
The PWB is often common to other hardware codes, component placement in manufacture will be to suit a particular hardware code. You need to go digging on those dusty old Ford servers to find out all the PWB/Hardware code/Catchcode/Feature set combinations. Oh, and then share it with us!

But I could maybe steal the EGR output to make it happen? But then I would have to find another output for a high/low fan function if desired?

All possible hypothetically.
PWM points are on DUCE or DARC chips. There is some info in the manuals, handbook and strategies. Start looking in your PCM to see if any chips match the documents.

I guess to sum it up I would like to add some modern features and make it all operate like it was factory equipped. I am very OCD/nit-picky about things like wiring and aftermarket components that do not integrate seamlessly.

The option of using a more feature rich Ford EEC-V box should be considered.

Then after finding or adding components I would have to figure out how to add the needed code to make it function, is there a write up somewhere for adding extra code to factory code and recompiling the BIN file properly to make it all work?

No write up I'm aware of.
There is no compiler, it is done by overwriting the BIN hexadecimal with a hex editor.
You may need to make space in your BIN for extra code, by stripping out redundant code.
You may be able to repurpose redundant code.
You might be lucky, your BIN already has the necessary code but it is just switched off.

This bin was hand coded with a hex editor. Partially cut and paste from another BIN and some bespoke code.
https://github.com/OpenEEC-Project/EEC- ... -Test-Bins

the v10 trucks use a similar ecu but none are an exact match

problem with the harley/lightning ecu is there aren't many outputs that aren't used. There are no eec-v ecu's with more hardware as it uses all of it.

you can use the ic output for fan control if you wanted and just hook up the ic pump to the fuel pump trigger.

yeah its easy enough to write the code using a hex editor. I use tunerpro and just write the code using a patch makes life simple.

If you can read code you can write code nothing to it really just time consuming.

Do you know if there are any pwm outputs that could be unitized? I have deleted egr, and waste gate solenoid for sure. Rear cat monitors also deleted. Knock sensors deleted, I know those are inputs mainly. I was thinking using an older fusion fan controller might be nice. Mainly because of the limited charging capabilities of the 4G alternators. I am not currently using the hi low fuel pump features either. I have a fore fuel pump controller on it now with both pumps at full speed. But would like to wire the hi low features of the pcm to the fore controller to keep the current draw to a minimum when the extra pump isn’t needed.
