Looking for Info on OBD2 GM 60*V6's

Ahhhh, no luck, was hopin though lol, program has tried about 400 keys, only 65135 left to try LMAO.

Will really suck if I go through all 65535 with out success because I have an error somewhere

Ahh the waiting game, I love that one, it's fun. even after I set the delay for 11 seconds after getting a 36 response, I would still occationally get 37's, that is why I set a trap to retry them (If it hit a 37 I would subtract 1 from the counter so when it incrimented the counter later it would re-try the failed 37) .

[planethax]

I am writing to a text file in hopes of trapping errors.

Does seem to crash every few hours (freezes) but at least I know where it left off and can view any errors,

I am currently rewriting to trap on 34 35 36 37 NoData and anything else
34 Succes
35 continue
36 wait 10 seconds
37 wait 10 seconds subtract 1 then continue
No Data Stop
anything else Stop

The 10sec wait game gets boring pretty fast The OBD-I flash PCMs we have in Oz don't have this so can get through all possibilities in around 3 hours.

The latest PCMs are using rolling seeds so cant use the normal brute force method.

[planethax]

I have come across a rolling Seed/Key in GM yet but guess they are out there.

Well I sstarted at FFFE am now at CE93 lol
A ways to go yet.

[sabercatpuck]

I am thinking I may remove the seed key thing altogether on mine, if nothing else it would probably open up at least a little space to put something else in Although since one of the big wish list items from the Saturn guy's is to be able to put in a manual tranny and still have cruise control. I was thinking about adding a error for a diff pin malfunction since the VSS is very nearby (you can inspect the dif pin through the VSS hole) I was wondering if I could detect a loose diff pin as an anomolous reading on the VSS. But that is for another day and another thread

[planethax]

Well I have figured out why my app freezes every few hours, using a textbox, and it has a limit of 65535 bytes, need to use rich text box.

[planethax]

C96C lol

def need to optimize code, right now it pauses 10 seconds each try, I am still working on it pausing only after 2 tries then looping.

[sabercatpuck]

Might try adding the traps, after a 33 (though I doubt you are getting any of them using a program to run it) just re-try the last number. If it was a 35, incriment and try the next one right away, If it was a 36, incriment and wait 10 seconds, and if it was a 37, wait 10 seconds and try the same number again. (woops, I forgot you are working backwards, in your case decrimnet not incriment)

[planethax]

LMAO well after a few days, seems my key wasn't found.
Hmmmm, Well I did mess with it a few times, better try again.
NOPE, no key.

Finally finished coding for the Traps of 33/35/34/36/37 etc, and realized I had an extra whit space I was not accounting for lol,

Everything got trapped in the Wrong key section, DOOH!!!!!

Ok, well I think I have it sorted now, also running faster as only waiting 10 seconds after a 36.

Also, having it dump current info like key tried, time running and the list of keys tried into a text file,
so if there is a crash (have had 2 after 9 hours of running) progress will not be lost, the most that will be lost is maybe a dozen or so keys tried.

Once I have it find my key and test it, I will upload program here for anyone who wants it.
