PCM Hammer P01 and P59 flash tool v015

[antus]

feel free to add it in and send us a pull request. we might also add something to stop it uploading the wrong kernel but knowing the algo and which osids and maybe allowing a test unlock would be a step in the right direction.

For my own curiosity, what's different about the unlock algorithm in the V6 PCMs vs the 0411? I generally understand how the flipping/endian changes works to generate the key on the V8, but I can't find any details about the V6.

The following is my personal opinion and is just that, My opinion!

In the flavor of this being a hacking site ...

I personally think that PcmHammer should not be crippled in it's abilities to prevent stupid people from doing stupid shit when they are told not to unless they understand the consequences.

Otherwise handcuffs are applied to those that do know what they are doing and choose to be adventurous.

-Enjoy

Hi all,

Has anyone here tried using a Bluetooth Adapter with the PCM Hammer App?

I ask because I wanted a relatively inexpensive one to use with my Android Phone to monitor engine data, so I found and bought a used BAFX unit off eBay for $15.
As best I can tell, it uses the same interpreter IC as the OBDLink LX (and SX): the STN1110.

When it arrives this weekend I'll give it a try and post the results here.

edit 2/6/2019;
My order arrived today, so I tried out the BAFX device. Works with Torque Pro just fine.
Tried Pete's Android apps, does NOT recognize device.
Opened unit to examine IC - it uses a PIC 18F2480. SO, it is a true ELM 327 clone.
Oh well. in a couple of months I'll get an ALLPro USB.

Mike

Isn't the dream that the current 0411 kernal will flash a v6?

[antus]

It'll probably be another kernel, with this one as a starting point. But its unlikely to be the same kernel. RAM (code space at run time) is limited and there is no need for it to be the same kernel. Most similar apps have a different kernel for each supported hardware platform and its no problem to implement it that way.

NSFW,

Below is the output from the read attempt and fail I promised on the 2003 1 Meg 12576106 PCM with Intel Flash AB28F800. Let me know if you need anything else.

Here is the PCM Hammer output of the Results Tab and Debug Log Tab in a .txt file:

Edited post: I think I see the problem here. We'll take a look at the code. Im not sure the upload request part has the right length, and it might be that some OSs answer OK blindly but yours drops the request. Being a 1mbyte OS it would be later generation code.

That's really weird because I have it working with my Intel Flash P59 PCM.

Picture of mine attached.

It is from a 2003 Chevy Express Van 4.3L (Same part number etc as my 2003 Chevy S10 4.3L)

Attached is a txt file of the full debug.

Same service number and hardware number. Interesting. Your OS would be for a 6 cylinder. I wonder if it has anything to do with the operating system like Antus mentions above. The OS on the 1 meg P59 above that I am not able to read with PCM Hammer is:
