False positive with that AV. Early versions were packed with confuser because of perceived potential IP theft when it was more ground breaking. I ended up partnering with NSFW and later others and we...

@babywag: you can change vin, but not vats until it can write a calibration.

@mecanicman: Sorry no updates.

Sorry no news, having trouble finding time amongst other projects. Still want to complete this!

Good to see the interest :)

dave, you are correct about what you can currently do. I do expect write to get there, but until its done its possible (but unlikely) that show stoppers will come up....

The project is still alive but there are no updates currently. Thanks for the interest, knowing people are waiting and want it helps provide the motivation to make time to work on it.

Jayme has updated the AVT 852 ADX. It now supports 1x and 4x in the same ADX, can read trouble codes (DTCs), and supports wideband in the data stream via the AVTs ADC input where fitted. We have...

The only problem is the 68HC58 is EOL. But I bet it is still available somewhere. Its the VPW chip the pcms use, as well as the AVTs. Definitely the best way to do it. But not the only way, and still...

Yes, it has been tested, but did not work. There is a possibility that v6 will be supported one day, but not yet.

Of efilive vs hpt I would also say efilive. But for hobbyists hopefully this tool is the best option :)

V1.05 has been released. It can unlock black box pcms and display your seed/key, but they have been found to be incompatible so no read support at this stage.

Ive also set the virtual serial speed...

I should be able to work it out without that. I have PMd eaglemark so we can do some testing.

Well, the duramax just happened to work. You can try a black box PCM, but Its an early enough generation that I do not expect it to work. I wont say never for write support, but at this stage it will...

Excellent, thanks for the report :rockon:

I think I might add a usability tweak and put an error about check your connections in, instead of just "failed to read block 10" which is not so clear.

Is the connection to the pcm ok, ignition power on? Thats what it'll say if it can talk to the avt but the pcm isnt replying (block 10 is the first thing it tries to read).

Ok thanks for that. Appreciate the info, I dont have one of those PCMs so its your report that gets it added. Ive attached a 1.05 beta to this post (will remove it later). It has that pcm type...

Whats the OSID and the Service number of that pcm? I added the OSIDs for the 1Mb PCMs that I knew about but it looks like there are more to add.

v1.04 has been released. A few fixes for LB7 duramax.

If you mean something that can fudge the tune to make the data match the original checksum, then sorry no. A flash tool should not edit the tune, only read and write what you supply.

Ive updated to v1.03, added some more duramax osids, fixed the user key function, and fixed the handling of a seed response asking the tool too delay and retry.
Theres not much I can do to support...

thanks, will have a look at it.

Have released V1.02, with support for 1MB PCMs. Testing reports welcome.

"The application failed to initialise properly 0x0000135". This means your machine does not have the microsoft .net framework on it. There is a link to the download it from microsoft in the software...

good to see your here :)

Buzz: thanks for the detailed level of testing, much appreciated. I dont think there is a way to get the pcm service number from the pcm, so to properly identify a 9354896 pcm I will need to create a...

Yeah not there, after you hit read its in the detail log box down the bottom, but scrolls out of view. Ill update the interface in the next version.

Good to hear :) The key is logged if you scroll back in the info window a couple of lines. I can add the seed if its useful.
