I have searched everywhere, I haven't found a clear answer. I need advice on how to take an unzipped patch and use it with my custom bins in both Tunerpro and Tunercat. I can't find the dummies guide to applying patches. My DIY-WB is done & working, my boosted $58 is running, time to datalog & pass emmissions.

Tuning guide, Chapter 2 "Patch Method"
Of course the patch must be written for use on a specific bin.

Yes, I read that. It doesn't say how to use a written patch in a bin file. Lets say I already have a WB patch for both Tunerpro and Tunercat, how do I use these patches? Where do I install them?

The patches add the required "code" to the bin file.
TC & TP only need the definitions changed to be able to edit parameters associated with the new code of the bin.

OK I got that part. I'm just not jumping the gap. If you had TC and wanted to add a WB patch, how would it be done?

With TC I believe you need the definition editor program (I use TP because of ease of tweaking)
This thread explains alot of what is needed although a bit confusing because of all the options that were being thrown around.

Basically you just need a way to set the correct bit to select the sensor option you want.
From there you only need a datalogger that can read the datastream item # 37.
The WBAFR comes out of there as 10:1 to 20:1
This is shown as "IAC MIN" in DataMaster ($8D)

There should be a text file with the patch to explain what bit to set too.

If your trying to do $58 based wb logging.
There are two options.
There is single sensor patch for it available.
Or you can run the $59 bin which has it.
Try looking through thread linked in the very first post of this thread. It has info on both options IIRC.

As far as appling patches.
Do you mean editing the patched bin cal section or
adding the patch to the bin for the first time?

I just want to add the patch to my bin so I can log with datamaster on my $58 platform. I have the tdf editor for my $58 bin file, it is quite intimidating to look at, from what I have read the WB output goes into pin F14 and is read as desired AFR. I just don't have any idea on how to edit my tdf file to make my ecm know I'm using pin F14 for WB & I don't know how to tell my bin its being patched.

Z69

Your need to research some more.

When you patch the bin. ie your $58 masked bcc.
The bin will be modified to look at pin F14 and read the voltage there. Then store that voltage (0-5v) as an integer of 0-255 in a ram location. The patch will also modify the aldl stream to read the above mentioned ram location and put that value into the datastream at the location that is normally the desired AFR.

The aldl table is basically a list of ram values.
The list is numbered 1 to 64 or whatever.
The various scanner software is set up to show item 27 for exampe as desired afr. The actual 27th item varies by bin.
The patch simply changes the 27th item in the list to read
location y instead of x.
You don't have to do anything with the tdf normally.
And the desired afr was chosen by the patch author so that the scanning software would display the value correctly.

I apologize for being a dumb a$$. I do understand how its all supposed to work, I just don't know how to take a patch and add it to my .bin in TC.

I really apreciate & respect all of you who help & write documents, I'm not looking for an easy answer and I do understand why its no just handed out. I'm just looking for a step in the process or a push in the right direction.

you don't actually add a patch in any of the tuning software. That might be where you are getting confused.

if you re-read the patch method sticky closely, you'll see that you run a small dos script which takes the patch, and applies it to a file. there is some not so quite clear things going, in that the file is in a S19 format, and needs to be converted to a .bin file, but re-read the sticky. i haven't done that in awhile, so I can't remember the exact specifics.

so basically, you add a patch, using a patch utility, then utilize the .bin file that gets generated. You then use that .bin, with the existing tuning/scanning software, and in this case, no changes to the definition are needed, because, as was said before, the output is already on a byte that is read and displayed, it just becomes a different paramter that is displayed.

in some case, depending on the patch, you might have to display the parameters differently, or from a different byte; in those cases, you need to modify the aldl definitions, or the tuning definition, becuase you might changed the code drastically, but thats pretty advanced stuff, you shouldn't worry about that until you become a code pro.

is that any clearer? i knows its hard to understand, the software side of all this stuff is always confusing to me beyond the basics.

87tpi7749

Its becoming more manageable to understand now. The parts that throw me off track are when people talk in code and write code, I get lost, since I have only used TC. And DOS?? Thats number two in Spanish for me. I have never used DOS.

One thing, how do I convert an S19 file to a bin file?

S19_PAT yourpatch.S19 0x8000 yourbin.bin

Breakdown:
Executable - your S19 file - your chip offset - the bin file you want patched

You must use the S19_Pat.exe contained in the zip file from that thread.

This procedure will add the contents of the "patch" to your ****.bin file

We aren't holding back.
Rbob is the only one who is excellent at explaining it.
Most of us can't make it simple enough.

Z69, JP86SS, JWSCAB---Thanks for the help. Got it figured out. Well until I datalog I guess. I actually patched two differnet ways, I used DIG'S patcher for one way and TC hooked me up with a bin mod utility which is very simple to use, even I was able to do it! I wouldn't have been able to do either without the sticky or help from you guys. I read Rbob's patch demo a few times before things started to come together. A big thanks.


I hate to be that pest who keeps posting questions which may seem trivial to others. In the spirit of TGO I'm glad that you guys overlooked my lack of knowledge/understanding and replied to my post. Thats what makes this the best forum ever.
