Betas Wanted for 60 work
Well, I have a second GN guy now that's running the 60 code, and is doing well. Two others are having issues with other stuff, and just haven't had the time available to play.
So if you're currently running a 749, with the 58 code give me a holler via email, and I'll give you a running copy of the 60 source code. I have a 2 bar, and 3 bar version, just let me know which version you want. And you'll have to spend some time comparing files to edit in your calibration. I say running copy as in I still have some editing to do, but, it assembles corrrectly and seems right.
Like all educational projects, you have to accept the responsibility of looking at it close enough to see if it seems safe to use. No warranty expressed or implied. For educational purposes only.
Being a Beta gets ya, absolutely nothing other then a first peek, at what's coming.
The 3 bar is something new, and a down and dirty answer. So far it seems fine on my car, but I've been using the WB and building the tune slowly.
So far it should be editable with anything that'll do a Sy .bin, if it will allow for the lenght being 32K instead of 16K. The 58-32.tdf for the 32K file is for when you double load it in just the upper half.
The game is afoot................

Grumpy -
you can count me in for a 7730 until i find a 749(if any one has one they dont want/need anymore and would part w/ it for cheap let me know) i just need to drop in the motor and finish the harness
also iv been looking over the 58 stuff and have had a few ideas for some software, but w/ the car(motor and trans) and school its going to be a while till i can do anything w/ the software.

grumpy everything works exactly as it should. EGR included. Tested it by copying every setting from my wifes car ( which runs a 749 n/a with $58 code) and no problems. Everything is perfectly functional. Car just passed maryland emissions when we brought it from florida which it did before the code swap.
Couldnt be better there is perfect stability.

The reason the airflow calc returns zero on a V8 has to do with the cylinder number term. On a V8 calibration this term is set to zero. In reality it is 256 ($100). But the number 255 ($FF) is the largest single byte value that can be used. So GM sticks a zero in there.
Now change the airflow routine to load the number 255 instead of the cylinder number term. Wa-la, now the airflow term is usable.
A more inventive type could actually code the airflow routine to check the number of cylinders term and if not zero use it as is. And if zero then load 255 in. In this manner the actual bin/code can be used for either an 8 cylinder or non-8 cylinder engine without having to change the two bytes of code for each.

I wish I knew assembler as well as I know c.. Maybe Bruce will add a patch to $60 for this.
So it references the cyl number term. So on that insruction, just change it to use 255. Whats the location?

However, before I continue this patch is only an 8 cylinder patch. It hardcodes the bin for an 8 cylinder airflow calculation. So please keep that in mind.
Here is the section of code in question:
Code:
PSHB ; Move D reg to stack
PSHA ;
TSX ; transfer stack addy to X
LDAA LC009 ; Number of Cylinders (6=192)
LDAB #200 ; 200
MUL ; 8 x 8 mult Making this change will force it to load a 255:
Code:
PSHB ; Move D reg to stack
PSHA ;
TSX ; transfer stack addy to X
LDAA #255 ; for a 8
NOP ; fill
LDAB #200 ; 200
MUL ; 8 x 8 mult Addr is: to:
$2E8F $B6 $86
$2E90 $C0 $FF
$2E91 $09 $01
At each of those addresses change the byte to the 'to:' value column.
For the better 100% method, notice that all the code does is to multipy the number of cylinder term by the constant 200. So, lets just do that ourselves and load the result directly.
256 * 200 = 51200, or $C800
And do this:
Code:
PSHB ; Move D reg to stack
PSHA ;
TSX ; transfer stack addy to X
LDD #$C800 ; for an 8 cylinder
NOP ; fill
NOP ; fill
NOP ; fill Addr is: to:
$2E8F $B6 $CC
$2E90 $C0 $C8
$2E91 $09 $00
$2E92 $C6 $01
$2E93 $C8 $01
$2E94 $3D $01
Of course if one were doing a nice new set of source code (hint-hint) there should be a test of the number of cylinders term and do the proper math. In this manner patching for an 8/6/4 or whatever cylinder count need not be done.

Hrmm.. Why not just jump out, check if its 8 cyl or not. If its 8 cyl apply the 100% patch, then return. If not, load the cyl term, and return.. Theres tons of free room.
The problem I have here is we're doing things from different angles. When I work in the software world, we're patching source directly, and recompiling. But we got folks here who are using bins, and programs to patch bins.
If we're gonna standardize on tinkering with the source, we need
an easy way to import table data/constants from compiled versions. Any suggestions?
If I write a routine in a gnu patch file, that will patch Bruce's $60 source file, can one of you guys make it into a binary patch for everyone else?

As for putting together patches and a utility to apply the patch, see the sticky above called 'Patch Method Demo'.
As far as changing the $60 code, I do think I put a 'hint-hint' in my post. With source code there is no reason to jump out, do some code and jump back. Just write it in with the current code and re-assemble, done.

Ok. I got everything imported from $58 into $60 now.
The EGR airflow multiplier on Bruce's code is very different from what you posted Rbob, which appears to be stock $58 right?
In any event, I changed the multiplier to 255, so hopefully that will work.
I'm not sure if the source Bruce released had stock settings (iac, pe, ae, timing, ve and so on) or specific to his GN but they are far far far different than what I had in my bin (as far as the unchanged tables go obviously). So i'm going to spend the next few days tinkering and datalogging different table changes.

The Source Code is just that, source code, while it assembles, the user is responsible for verifing it's correct. Again, that's covered in the opening statements.
I don't know what more I can do to make it more self explainatory, then including all the info.......
You, meaning the user (not Joe specifically), need to read the manuals, and documents when given something to use.
RTFM, is for real.
Don't mean to sound like on a rant, I thought spending the time to write the header, and notes, would have prevented anything like this.

I didn't read it. I made a few changes and compiled it, and used
TC to compare a lot of tables. My bad. Rather than read the documentation, I "ASSumed" the filename was a representation of the bin. (stock58)
My bad!
