Wasn't pointing at anyone in specific ... Just in general.

I started a thread on the Matrix topic here: P01 and P59 Operating Systems, have at it ... Have fun!

I have a genuine MDI2 Bosch cable that I use for TIS2Web and SPS that I can test with nearly any of these PCM's if you guys need. If you all have a Bin file you need me to test write/read I can do so as well. Have unlimited licensing with the big brand software as well to help with flashing/testing.

MDI 2 should work with pcmhammer. It would be great if you can test and report back.

No dice on either a P01 PCM or a P59 PCM. Both of these computers are confirmed to work as well.

Here is the debug on each case.

Reading from 0 / 0x0, length 4096 / 0x1000

The kernel doesn support packet sizes over 2k. Thats a bug. We'll need to see how that got in there and reduce the packet size to 2k for all devices.

Hi all,

Just checked the AllPro website and found that the USB version is NO LONGER LISTED.
ONLY the AllPro Adapter Development Board @$25.
Does PCM Hammer work OK with this version?

Mike

Yes it does work but you'll have to supply your own usb to serial interface. I actually use one of them on my development workbench.

Hi all,

Antus, thanks for the reply.
I have an FTDI-based interface that was used with my 1994 Jimmy, so that isn't a problem.
Also have a cable from an Aluminum ELM327 device that doesn't work.

Here is the original 2003 Yukon p59 file with the vats removed.

OK, hopefully I provide enough information in this post! LOL! (I'm just picking on you Gampy... )

Found some time this afternoon to do some testing with PCM Hammer 5. Tried it on a 0411 PCM and everything is good, good, good! Using PCM Hammer 5, I read the contents of the flash chip and saved it as a bin file. Opened the bin in TunerPro RT and disabled vats, changed cylinder volume, and changed the VIN number before saving it under a new name. Opened up PCM Hammer 5 and wrote the changes to the 0411 PCM. Powered everything down before trying to read the same 0411 PCM again with PCM Hammer. After my second read, I open the bin again in TunerPro RT and all the changes where there. As an excersise, I reversed all my changes and everything was still good. That's the good news!

Disclosure: I understand that PCM Hammer support for what seems like a variety of flavors of P59's out there is not implemented yet. I am not trying to push anyone to get PCM Hammer to work with them. I am completely happy with using the 0411 for all of my projects! If PCM Hammer never fully supports the Blue/Green boxes, I could care less. So please don't think I'm needing this to work. I'm just sharing my experience in the hopes it helps future development for others.

I tried using PCM Hammer 5 to read a (arrived new to me this afternoon) P59 PCM and it failed. The PCM is a year 2004, 8.1L truck with 4l80e, Service# 12586243, Hardware# 12583659, with 1Meg Amd AM29F800BB flash chip, OSID# 12612114. This OSID doesn't show up anywhere in my collected notes, but I did find a reference to it on the HP Tuners forum. From what I read, it is NOT a custom OS. So I guess it does exists out in the wild.

Anywho, when I try to read the PCM using PCM Hammer 5, it fails to load the kernal (I also tried reading the same PCM using PCM Hammer 4 with the same results). I read the PCM three times, powering down and shutting the application after each attempt. The first two times I got different outputs in the Debug Log tab. The second and third try has identical Debug Log tab output. I found the difference between the first and second read so great, that it might be of interest to the developers.

I was able to read the same P59 PCM using my shiny new BDM NT fixture I built, and open the bin in TunerPro RT using the OSID 12587603 xdf file. Even though the operating systems are not a match, it was able to correctly identify the OSID, engine type, cylinders, transmission type, and the VIN number. So I'm guessing there is something right about the bin file.

Note: When attempting a read, I always apply power to the battery pin, wait 15 seconds, apply power to the ignition pin, wait 15 seconds and then start the PCM Hammer application. I'm trying to let the PCM safely bootup before messing with it. When I shut down the PCM, I turn off ignition power, wait 15 seconds before shutting off battery power.

See attached zip file of the first two read attempts on the: P59 PCM, year 2004, 8.1L truck with 4l80e, Service# 12586243, Hardware# 12583659, with 1Meg Amd AM29F800BB flash chip, OSID# 12612114:
Thanks and take care,
