From your Archiv.zip...

First log:

Code: Select all

11:14:01.522 -> 1000 pins in 573 ms, 1745 pins/s, average response: 20 us, histogram 10 to 30 us

20 us is too low, something is not right. Won't work.

Second log:

Code: Select all

12:59:03.981 -> 1000 pins in 639 ms, 1564 pins/s, average response: 86 us, histogram 43 to 129 u

Latency is good for CEM-L.

Can you rerun the second test (when the latency is in 80 us range)? Don't bother waiting till the very end, just capture logs for the first pin position. Do it a few times. It will show us whether the discrepancy is there, but the cracker sw takes the wrong decision.

Anybody knows if these guys had their "detector" working with P1 and late P2s before we wrote the cracker?

Not working with early (99-04) P2s is sort of suspicious: we haven't yet figured that out

That is MVS member Yagger stuff and it works. He is way way ahead of us on this stuff. His stuff is what cracked Frankenstein before we started this. He was telling you about it early in this discussion.

I see. Well, saying "bring me your money" is not way way ahead

At least we provide an alternative for those inclined.

Talked to him a while back and he said he was getting a lot of work from people that got things messed up playing with Vdash. Talked to him earlier today and he was swamped with work. He might be undecided on whether to thank us or curse us.

Well, myself and the other guys have had a great time hacking together

It is worth every beer we drunk over what became a cracker. Sort of a mental exercise, a bright moment in a totally gray and dull adult's life.

Sometimes the journey is worth more than the goal. Nice to be associated with people that get it.

Same here. Even if my part was flailing around trying the crack my PIN with what was presented here.

You are wiser for it and, way ahead of those that are too busy thinking they already know it all to actually learn something.

That is why some people call screwups, real beauties.

If your Cracker is still bread boarded. Check the connections. I made heavier gauge jumpers out of Paper Clips. It made a difference. You could use solid copper wire to make heavier gauge jumpers.

Which CAN transceivers are you using? Some people had trouble with the 3.3V CAN transceivers.

Do you have the Latency detect jumper installed? Some missed that because VTL forgot to include it in the original schematic.

The Red jumper is the Latency detector ( PIN #2 to #23, Both fourth from the end ).

Hi,

it is not bread boarded. I soldered it on a circuit board. I have the bridge for latency soldered and I used 1,5mm2 wires. I thin they are heavy enough.
I use the Waveshare CAN interfaces and cut the resistors for termination. Please see my photos. Should I try some other CAN interface?
