Uploaded Update file.

As always, comments criticisms and suggestions most welcomed!

Robert, I had a 95 Jimmy in the shop today so I quickly tried it,
app connected ok, but had errors as OBD1.5 reports a little differently, but very similar.

Once I find the PCM I have I will wire it up and make necessary changes.
I may be able to incorporate both into one and either have it auto detect or User selected.

Nice interface!

HEHE, thought a Tech2 image would be fitting lol.

Lets just hope I can get it to flash the files now.

X2, it is rather fitting...

I downloaded it, but won't have time to mess with it for a bit

As a note, if it crashes checking vin, that means Pid 09 02 is not suported.
I am adding an error trap and going to get the vin via
3c 01 02 03 04 as they are supported in all OBD2 as far as I know.

I am just starting to run on another Pcm (with a higher seed so may take a day or 2) after that I will update code and reupload.

The only dependant files are vbruntime and Jet ADO which should be preloaded on any XP/Vista system.

Let me know if you have issues?

Anyone try it out yet?

All I ask is if you do use it, and your OSID is not listed please send me the OSID with the Veh info so I can add it, and if you run it long enough to get your key (last one I did took 8 hours but could take upto 4 days) send me the Seed/Key and Osid so I can add to DataBase.

Well, I started checking another PCM last night,
Seed was 33 E2
key was 42 CE

Only took 23 hours to get, so not too bad

i may have better results with the OBD1.5, even punching in everything manually...

hyperterminal didn't seem to like my laptop(said i already used my trial), so i found putty. think it's on sourceforge, it's a decent setup as well....

The thing with hyperterminal and similar terminals, is that the PCM MUST get the commands in a timely fashion, mili seconds for some, impossible to type that fast.

you can try this terminal though

Vista is a btihc, even with my app you will need to create certain text files for it to run (I just remembered about that)
With vista create 4 text files named
reume.txt success.txt Timer.txt and connecttext.txt
They can be empty, vista folder are setup differently.

I will add the blank text files with next update.

true, but shouldn't the terminal send the entire string at once instead of as it's typed? or at least there should be an option to do so...

example to get seed/key

you send
27 01 > enter
you get 27 01 XX XX <- ur seed
you send
27 02 XX XXX <- ur key > enter

between the 2 enters, you must recieve the message and then reply within mili seconds.
Would be hard to even copy/paste the commands in

Maybe I can set up a program where you can select from a possible1 to 10 lines of commands depending on checkboxes, then you input the commands you want to send then hit the button and it will do all the work and print the replies to a textox for you to see?


I will see what I can come up with as I am wanting to make something similar to just monitor the dataline.

what kind of input is this expecting? and how are the sent and recieved bytes delimited? i tried space delimted hex this morning and got nowhere fast....

What are you using to connect to the PCM?
