Turning on Digital Speedo - VY VZ OSE Flash

[Ken]

Apparently the above mentioned dash software is a no-no to talk too much about here on the forum so I wont get into too much
detail regarding it's potential/fucntionality, just mention what I found to work for me.

Firstly, using the wrong version of Common Controls gave me grief regarding functionality.

Secondly, the program has references to cache files that weren't part of it's download.

Apparently created by msvbvm when needed, though I'm thinking it's if VS is installed.


Thirdly, registering the program with regserver from the run command or command.com
eg:
|<------------Path------------\------File Name--------/
C:\Program Files\VYinsDiag\VyInsXXXXXXXXX.exe /regserver

command.com - Path\----------FileName-----/
C:\Progra~1\VYinsDiag\VyInsXXXXXXXXX.exe /regserver


It's targeted OS is mentioned internally, hence the path to the cache files.

I'm wondering if it's something to do with some errors I was previously getting about missing files:

- COMCTL32.OCX
- COMDLG32.OCX
- MSCOMM32.OCX

I found them online and placed them in the same folder. But maybe they need to be installed somehow? (I'm really not an expert here).

I might setup a virtual machine and play around until I break something in there

yes you do need those files. i just checked i there are a bunch of additional downloads in the directory to get it working.

i dont think there is any issue with discussing it etc. the cars themselves ended production in 2004 before they shifted to vz. while the app will work with the vz dash it's hit and miss as to what it can do. I've used it to chnge the basic dash cluster boot name etc, but thats about it.

That one in particular needs to be renamed, caught me out when I first tried using the app, it wouldn't register using regsvr32,
turns out the ".OCX" file extension needs to be renamed to .zip.

This is the header of the file when opened with a hex editor.

Yeah I thought that would be the case too, and posted a video showing how using the same username and different password is what
unlocked the different levels, it was immediately deleted and a warning from Antus in a PM advising of it being a problem talking
about it openly.

I forgot to post a fourth step to getting it working in my post above, registering the .OCA cache files using regtlib.

just re-registered them again for the purpose of taking a screen of the outcome for the post here.

lol your right. that is a zip file.

i uploaded the files years ago, so not sure how i managed to fck that up.

Is anyone else getting "runtime error 6: overflow" and crashing?

I've been playing around with it a bit and wondering if someone may be able to help me understand something.

Whenever I write something to the cluster (change configuration etc.) - there's always a response / error code (I'm assuming that's what it is) of 01 returned.
Immediately after that, the software starts sending messages with a 3rd byte / 1st data byte / mode byte (whatever you wish to call it) of exactly 1 more than whatever was used to do the configuration / write / etc.
The cluster keeps returning 04 multiple times, until eventually it returns 00. That must mean complete / finished / whatever, and the software stops sending anything else.

EG. Writing a configuration option. Mode 20 to do the change, followed by polling the cluster with mode 21:
F2 5A 20 55 00 E4 00 5B
F2 59 20 01 00 E4 B0 <<-response code 01 returned
F2 57 21 00 96
F2 59 21 04 00 E4 AC
F2 57 21 00 96
F2 59 21 04 00 E4 AC
<above 0x21 exchange repeated many times>
F2 57 21 00 96
F2 59 21 00 00 E4 B0
finished


another example, writing the VAP data. Mode 28 to do the change, followed by polling the cluster with mode 29:
F2 65 28 05 <VAP data bytes, same as data table 7>
F2 58 28 05 01 88 <<-response code 01 returned
F2 56 29 8F
F2 58 29 05 04 84
F2 56 29 8F
F2 58 29 05 04 84
<above 0x29 exchange repeated many times>
F2 56 29 8F
F2 58 29 05 00 88

What is this all about?
I've been reading the EERPOM before and after changing things, and it seems polling the cluster after sending the actual command makes no difference - the setting is still changed anyway (even if you don't do it).

I'm using an ALDL cable purchased from here a long time ago.

Might have to put together a MAX232 cable, there's a post here stating that's all they could get working:
viewtopic.php?p=94147#p94147

have you tried to do read of the general cluster info?

"File > Get Instrument Details" is greyed out.
I've got AAPL level access using cheat engine. Most of the other features either timeout or don't do anything.

Have you got any more info on the aapl access with cheat engine please mate?

I ended up getting it working in an XP virtual machine.
Can confirm the 8192 baud error at startup is normal - it works fine despite this. But most of the software works, and I've confirmed the data is being sent / received using an oscilloscope. There are a lot of bugs in the software though (eg. when trying to load one of the data tables I get an index out of bound error and the software crashes).

Can't make it work in windows 10 though. It does seem to half work - I can see a BCM enable chatter command being sent periodically when in one of the menus (which is the same behavior as in the XP VM). However whenever I try to actually do anything in the menu, it just does nothing - no data actually transmitted. Where as on the XP VM there's data being sent in between the enable chatter commands when you do something, and the software works.

And yes it is sending an enable chatter command - not a disable. Maybe another bug in the software? or maybe its trying to see the clusters response to the BCM message? who knows.

Also had to modify the cheat engine script I found somewhere years ago to get aapl access. The latest version of cheat engine I could install on XP was 6.7 which didn't seem to work with the script. In the end it was only 1 simple thing: the script contained a "nop 4" line (4x nop's). Just had to replace that line with 4 individual lines of "nop" and it worked fine in 6.7.

Any chance you"d be willing to have a chat about the access script mate? spent the last 3 hours searching for where you found it to no avail

I've attached the script here.
I cant remember where I found it now either, it was a long time ago.

I never actually got the software working on win 10 (it worked, but refused to send or receive anything from the serial port). If you get it working let me know what you did.

In the end I set it up in a XP virtual machine. I had to use an older version of cheat engine compatible with XP. And there was something about the script that was incompatible with the older version that required changing. If you have the same problem, I'll dig out the VM and get the script off it.

I still can't get past that baud error, Still stuck on that loop! haha
