And may I ask what that is ??

Just double checked the data sheet, and its 12 including header and checksum (checksum is almost always hidden on most tools).

Thank you!

Thought I would post these logs ...

Packet size is 1 + 12, PCMHammer will not do 12 bytes.

The absolute minimum for sending upload is

3 bytes header + 2 bytes mode/submode +2 bytes size + 3 bytes address + 2 bytes data + 2 bytes block checksum
14 bytes total +1 byte crc checksum

the 77 error means block checksum is incorrect.

increase data to 2 bytes, that cpu really don`t like odd address and single odd bytes count.

I will try ... However it works one byte at a time using 1 + 12 with other VCI's, it took 10+ minutes to verify a P59!

With 1 byte of data you still need 13+1 bytes buffer for sending

How long did that take to read!!

[Gampy]

I have no clue, I suspect PCMHammer's debug log will choke it!

So. Just found out that godiag has updated firmware and software now. One specific update is for j2534 TX size set to 4128. Looking at it now to see if their update may actually fix it.
