ARAPWB for linear WideBand - Third Generation F-Body Message Boards

400Z28Racer · 06-19-2009, 02:08 AM

While back I did APYPWB which enables linear wide band dataloging
http://www.thirdgen.org/techboard/di...6e-linear.html (APYPWB MAF 6E Linear wideband dataloging is here)

However, some people are having problem with the torque converter not locking up with APYPWB nor APYP, so I decided to implement WB to ARAP
http://www.thirdgen.org/techboard/diy-prom/529620-anyone-using-apypwb-bin.html

The ARAP requires more work to enable WB because of the execution cycle;in other words, I can't stick the WB code anywhere, so either I change addresses or remove instructions. Anyway address CB1A is where I think a good spot for the wide band

Code:

 
        ;--------------------------------------------------
        ;   ENG RUN TIME COUNTER 
        ; 
        ;   Do not Inc time if eng not running 
        ;   Time in Sec's = 80 x .0125 
        ;--------------------------------------------------
CB1A:            LDAB    L0035                 ; Get Mode wd 1
CB1C:            BPL     LCB23                 ; BR IF ENG NOT RUNNING
                                            ; ... else  
                                                             
CB1E:            LDX     L0019                 ; ENG RUN TIME (sec) 
CB20:            INX     
CB21:            STX     L0019                 ; ENG RUN TIME (sec) 
    ;---------------------------------------------

        ;--------------------------------------------- 
        ; If no Comm >= 5 Sec Force mode 0
        ;  (TM'R VAL AT C70B)
        ;---------------------------------------------
CB23:  LCB23     LDAA    L0166                  ; SERIAL DATA TIME TO FORCE MD 0

so I am going to change it to this:

Code:

 CB1A:   LDAA #$00    
 CB1C:   JSR  LF2F7    
 CB1F:   STAA $0170 
 CB22:   NOP
     ;---------------------------------------------

        ;--------------------------------------------- 
        ; If no Comm >= 5 Sec Force mode 0
        ;  (TM'R VAL AT C70B)
        ;---------------------------------------------
CB23:  LCB23     LDAA    L0166                  ; SERIAL DATA TIME TO FORCE MD 0

I'll try to finish it up soon, time to go to sleep

You won't be able to change the values like that unless the entire file is relocatable.
Not sure if that file is already or not. If it is relocatable then you do not need to remove the engine run time counter, just add lines after it. The labels that used to indicate the locations within the file are just "names" then.

The only way to make it work without a relocatable file is to ensure the commands are the same size and will directly replace the existing contents (can't shift any locations or code will not realign when jumps are called etc)

The other thing is you have removed the engine run time counter update. Other items will reference that data for confirmation of run time. Probably will cause functional troubles. Best to find another spot.

Is there a read to an input that is not used in that code?
Such as an oil temp read that can easily be changed to read a different channel number. That way all you change is the channel number and then the ALDL address that gets data from. Everythuing else would be there already.

I hope that was a good explaination indicating the how that needs work.
If not post and I'll go into the specifics more.

I was aware of it

Code:

***** original code for ENG Run Time starts at CB1A and ends at CB22****

mine starts at CB1A--> CB22
CB1A:   LDAA #$00    
CB1C:   JSR  LF2F7    
CB1F:   STAA $0170 
CB22:   NOP

CB1A: LDAA
CB1B: #$00
CB1C: JSR
CB1D: F2
CB1E: F7
CB1F: STAA
CB20: 01
CB21: 70
CB22: NOP (which is a place holder)

I checked the code, and it seems to interferes with some error code parameter

I have to take a look
edit: I checked, and I could not find any

Thanks for your great help

That source file is good for reference but will not assemble any way, shape, or form.
I started over and got a file to reassemble and match the original.
Its a good starting point.
The file is WinRar but renamed to zip (WZ should work it too)
Don't forget to use anything but IE to download it.

JP86SS · 06-20-2009, 01:40 AM

The next step is to see if you can insert the code without making any addresses shift. Confirm by checking the LST file when reassembling with each change.

I'll poke away at getting this source to be relocatable using the APYP code as a reference. Once that is done, Then you can add whatever you want (within reason anyway)

400Z28Racer · 06-20-2009, 01:42 AM

you've done an excellent job! I would like to take a look at your control file since mine had a lot of lumps. can you paste your CTL please?

JP86SS · 06-20-2009, 09:58 AM

I used the APYP file as the basis. It did a good job but left sections of the ALDL in shambles. I had to recreate that part by going byte by byte through the bin file while comparing that info to the hac descriptions.

There was another problem at FFEE that "should" have been directed back to $0000 but was sent to a labled address that was not used anywhere.
ti1Vect (IIRC) was the one.
Here's the control file I used.

Code:

; This control file is called APYP.txt
;
input   ARAP.bin       ;this is the binary input file
output  ARAP1.DIS      ;this is the disassembly source/listing file
load c000

ARAPWB is ready

now time for testing

400Z28Racer · 06-22-2009, 02:15 PM

so far so good. TCC works as expected, and no error codes. The ARAPWB will be posted in few days

JP86SS · 06-22-2009, 06:15 PM

Did you take out the run time counter or was there a better place to put it?

bl85c · 06-22-2009, 08:56 PM

Are the maf read locations original or did you need to move them again?

Yes, I did take out the eng run time. I found something interesting in the code

Code:

D690:            CLRA               // ACC A=00
D691:            CLRB              // ACC B =00
D692:            STD     L0019   //ACC D which is ACC AB=0 
and it is stored in $0019 eng run time

I never changed MAF locations in ARAPWB nor APYPWB

bl85c · 06-23-2009, 09:41 PM

??? Rbob? Somehow they were moved.

well because you are using different maf set up.

anyway, Highway mode is not working in ARAPWB. I need to find a different location to add WB code.

400Z28Racer · 06-26-2009, 01:10 AM

New location found !! who needs power steering switch ??

. time for testing

Code:

****FROM****

I do, but the code doesn't work anyway. LOL.

I am an a$$hole for wasting your valuable time, and not writing a code for your car

bl85c · 06-27-2009, 04:24 PM

WTF? What's with the attack guy? I meant the power steering code didn't work- from the factory.
