I know there was interest in the past being able to read and write flash memory on the P10, P12 1mb, and P12 2mb PCMs. I saw a very old post on a different forum where someone posed a picture of the circuit board of a P12 1mb PCM and I decided to post an update to it because I was currently in the process of decapitating chips in both the P10 and P12 to learn their anatomy so that PCM Hammer would be able to read those PCMs instead of just the 0411, P01 and P59 PCMs.


IDing P12 Processor, anybody work at Delphi?

Teaming up with the guys over at pcmhacking.net, we were able to get this done. I provided pictures of the chips along which documentation for such to help with this development. Aside from that, I ran many tests for amazing software programmers over there. Because of their AWESOME programming skills, experience, and wanting to provide something free to the GM owner and enthusiast community, I am able to provide you with an update that a brand-new release of PCM Hammer is out fresh off the press today. This new version not only can read and write to the 0411, P01, P59 intel and the P59 AMD PCMs, but now it can also read and write to the P10, P12 1mb and P12 2mb PCMs. A special thanks to Antus, Gampy and Kur4o over at that forum for taking on the task and helping me turn it into a reality. I am so psyched about this and would love to see the developers of Universal Patcher add tuning support for these PCMs. This software is free and open source. Feel free to spread the word and try it out. For those that do a full read on their P10 and P12s, if you could zip it up and send it to me then I can pass them along to the Universal Patcher guys can work on mapping the calibration and DTC tables so that tunes can be done. If you feel like you want to help develop any ideas at all about any PCMs or improvements to the existing software, feel free to shoot over there and post about it. I have included below a list of vehicles that use one of these PCMs, which is correct to the best of my knowledge.
