Hi, friends
Has anybody tried the VTL P3 code?
After powering up on bench P3 CEM 2008 (pn 30765624) i get the same message repeadingly.
"p3_cem_get_seed: ugh...
CAN_HS ---> ID=00000726 data=03 7f 7f 11 00 00 00 00
CAN_HS <--- ID=0000072e data=03 7f 7f 11 00 00 00 00
what? ID 72e, 03 7f 7f 11 00 00 00 00
"
Tried many times. Some time it gets the seed, but after about 10 seeds, it gets "ugh" again.
Thanks.

Ran it through three different virus checkers all three say it is infected.
My checkers pick then up after the file is unpacked.

I'm sure there are no viruses there. I've been using these programs for a long time. The crack that was used to unlock the software is detected by the antivirus as a threat. Run the system in a virtual machine and check if anything gets infected.

United States DMCA update

Summary of the DMCA

Effective October 28, 2021, DMCA Exemption 13 will allow automotive device circumvention in motorized land vehicles, marine vessels, and agricultural vehicles when necessary for the diagnosis, repair, or lawful modification of a vehicle or vessel function. Additionally, DMCA Exemption 1 will be renewed for higher education uses of protected material.

The Automotive Supplier and Service Industry Successfully Obtained Several Exemptions

In 2015, the DMCA issued an automotive exemption (Exemption 13) that gave vehicle owners the right to circumvent digital rights management in order to perform vehicle diagnostics and make corresponding repairs. However, the exemption was limited: owners could not adjust the electronic control unit telematics or entertainment systems, vehicle software alterations could not violate U.S. Department of Transportation or EPA guidelines, and, most significantly, the exemption did not allow third-parties to make repairs.

In 2018, the exemption was renewed and expanded to allow for diagnostic and repair of telematics and entertainment systems as well as circumvention by third-party service providers for diagnostic and repair work.

This year, the exemption was renewed and expanded once again. On October 28, 2021, the exemption was expanded to permit circumvention of computer programs that control the function of a motorized land vehicle or marine vessel, including personal automobiles and boats, commercial vehicles and vessels, and mechanized agricultural vehicles or vessels, if necessary for the diagnosis, repair, or lawful modification of such function. However, the exemption prohibits circumvention of computer programs accessed through a separate subscription service. The exemption will be reviewed again in 2024.

Reference 37 C.F.R. § 201.40(b)(6) ( The final rules on the book )

Hum ... If we where to build up a baseline by doing random samples. Then sample bytes and subtract the baseline. Would the latency difference on the CEM-B become significant or would the jitter still hide the correct byte?
