PCM Hammer Release 017

(I just realized that I skipped 16. Oh well, the zip is zipped and the branch is forked...)

This release has no changes to the flashing utility but has a bunch of changes to the logger:

• Merged many new parameters.
• Improved bit-flag support.
• Support for signed values may not be correct, but is certainly improved.
• Reloads last logging profile on startup.

There hasn't been a lot of interest in testing preview builds, and my car is still on jack stands, so consider this a beta quality release until you hear otherwise. :)

Two warnings:

The logger might not 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.

Please don't make OS or calibration changes in your only car. This is new software, and you'll be among the first people in the world to use it. If something goes wrong, it may be a while before you drive that car again.

Reading and data logging are perfectly safe, though.

How to get it:

• If you're handy with computers, scroll down to the 'assets' section of this page, download the zip file, unzip all of the files into an empty directory, and run PcmHammer.exe or PcmLogger.exe. When the window appears, the first thing you'll need to do is select the device that you're using.

• If you'd rather not deal with zip files, you can get the apps from the Windows app store. This release is the "Beta" version for now, and it will be moved to the non-preview version a few people report that all is well. Just click the links below, and click the "Get" button on each page:

PCM Logger: https://www.microsoft.com/en-us/p/pcm-logger-beta/9png38rdzntl

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.

While we think it is just about impossible for this software to make your car unusable, please keep in mind that we're just a bunch of hobbyists who have been working on this stuff in our spare time. It's a miracle that we've gotten this far. If you need the guarantees that come with a commercial product, you should buy a commercial product.
