PCM Hammer Release 018
Posted: Wed Jul 07, 2021 12:25 pm
=================================================
=================================================
This is no longer the most recent release of PCM Hammer!
Look for the most recent release in a sticky thread at the top of the GM LS1 forum.
=================================================
=================================================
This release fixes the bug that led to garbage values in some logging parameters (any parameter that required more than two bytes).
Flash memory reading and writing is unchanged.
There is still an issue with the logger where it doesn't work well until you add several parameters. If you notice it pausing 2-3 seconds between updates, just add a few more parameters. It should update every 100 milliseconds or so.
Customary warning about flashing:
Please don't make OS or calibration changes in your only car. If something goes wrong, it may be a while before you drive that car again.
But, writing to flash memory is the only thing that can do any harm. Reading and data logging are perfectly safe.
The GitHub release page is here:
https://github.com/LegacyNsfw/PcmHacks/ ... 1.07.06.01
I'll attach the same .zip file to this post for convenience.
To test PCM Hammer, click Read Properties to confirm that you've selected the device correctly - it should print a few details about your PCM. Then try "Read Entire PCM" (it's in the Tools menu). And then, if you're feeling bold... and if you have a different car that you can use to drive to work... try writing the calibration or parameter blocks.
To test PCM Logger, select some parameters or open a log profile. Click the "record" button to save data to a file. The list of parameters we have so far is just the beginning, but it will take some work to figure out what we're missing. If you can help with that, please share at http://pcmhacking.net/ .
This project is still in its early stages. You may encounter bugs. The software may behave in strange ways. Please report such things to us so that we can fix them.
If anything goes wrong, please take detailed notes about the exact steps that you took, and please also copy the contents of the Debug tab and save it to a file. We'll need that to figure out what went wrong, how to fix it, and how to prevent it from happening to anyone else.
