I have a bootloader for a 28F010 now today, but the V6 PCM s have a 28F400, and I think the 1 meg PCM's have a different flash chip also. I need a bootloader and to understand how it works. I need a programmer that knows flash chips. All they have to do is buy a cable for that product line and get a before PCM BIN, and then an after PCM BIN of the editing of the tables. So they sit there and reverse each others tables. All the companies that have editing software today can upload and download every PCM that they have bootloaders, and seed and key algros for. I know exactly why they do this, and it the other reason a VPW interface needs to be on the market that can bring BIN files from the PCM and back to the PCM, for a before and after comparsion. HP Tuners also decided with 2.x software to encrypt the BIN files coming from their software. This will allow raw BIN files to come out of the PCM and upload back to the PCM. My intentions with the new information I have is use my VPW (AVT716 if you are intertested in what I have) interface that works on all GM VPW PCM's to upload and download. There is no reason that 1.x hardware and software cannot work with productline. The P12 PCM is a VPW interface, with 8 CAL segments just like the 04 V6 PCM. My reason for doing this was HP Tuners has made posts that they will not be supporting 2.0L EcoTec platforms on 1.x hardware and software. This one area has kept many companies from going forward with software and hardware for editing the PCM on GM cars and trucks.

I did not do it by myself, my wife actually wrote the formulas in MatLab, and between her math skills, and my understanding of how OBDII code works, we together cracked all 256 formulas for the Seed and Key process of the PCM. In the last few weeks, I have been staying up extremely late working on the cracking the algorithums to the GM PCM product line.

First, I want to wish everyone a happy holidays as we leave 2005, and start 2006.
