is there an issue with using 2022?

I mean there's not any inherent issues with using 2022 as far as I'm aware, but the step by step guide isn't going to be helpful at all imo if you're on 2022

I went ahead and got 2019 to make it easier on myself, I found where I needed to edit and add the OS numbers. I want to help provide as much info as possible so going to add comments to each line item for p12 OS that I am aware of and add the year/make/model (engine size). I will also make the change for the obdxpro and test that out.

awesome thank you. if you are able to use git and send us a pull request on github that'd be fantastic and likely accepted. if you cant or dont have time to figure that out, send me the changed files or post them here and I'll check them locally and submit them with a comment crediting you for the work.

I sent you a PM, hoping to do a proper pull request to keep it up to date when things get added

I did not receive it. You may have hit preview instead of send.

Hello, I'm having issues reading two different p01 pcm's! They are both from a v6 s10 with the 4.3. I thought at first it was because I had a guy disable vats and change some other stuff but I got another one from the junkyard and it did the same thing. Although I couldn't find one from a v8 vehicle I settle for another one from a v6. I'm currently using a bench harness setup with a vcx nano I purchased off ebay. also I've tried multiple dc power sources ranging from 11.84 volts to 16+ volts. It will not work on 4x but will upload kernel on 1x! I was able to do a test write and do a full erase and write but when I checked to see if it would read it after that it did the same thing. Also I was able to read an 02 p59 using 1x at 11.84 volts with no problem. I did notice it was held up at a certain block. Any help would be appreciated. also I'm not really worried about keeping the v6 file, so if I'm over thinking it and can just do a read over it and it will work then I'm fine with that. Here are the debug logs. Thank you!

Your power supply is pretty low as seen in the first log uploaded. I would be getting a power supply which offers 14v with at LEAST 1+amp supply.

Poor power supply = bad communication.

Quality of power is also important, many modern power supplies (especially PWM type) have poor power conditioning.

Intel's voltage requirements are: 12v +-5% = 11.4v -> 12.6v
Seems to enjoy it a bit higher ...

If you have the ability, test with a fully charged battery ...

About your bench harness, If you made it and left all the unused pins/wires in, ensure are there no shorts at cutoff ends.
Use Pin 60 as ground.

-Enjoy

My First attempt to read P12 PCM thru OBDLINK XL

I was able to read properties : [12:45:14:869] VIN: 1GNDU33L76D185590
[12:45:14:903] OS ID: 12601321

[12:45:14:938] Calibration ID: 12589693
[12:45:26:106] Hardware ID query failed: Error
[12:45:26:299] Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection.

Then tried to read entire

[12:46:32:901] Will save to C:\Users\MH\Desktop\4444.bin
[12:46:33:969] Querying operating system of current PCM.
[12:46:34:093] OSID: 12601321
[12:46:34:285] The PCM did not accept the key - too many attempts
[12:46:37:398] Unable to process unlock response.
[12:46:37:400] Unlock was not successful.

Not sure why it identifies hardware ID as P01, 059 i`m debating that this could be a tuner locked PCM.
