Software needed
My neighbor has a tech II that he is using to pull the programming from a 96 chevy suburban. He's looking for software to manipulate the file that it downloads. Anybody know where to find this without going to the manufacturer for the high dollar version. He will if he has to, but wondered if there were other options.

You can't manipulate anything from the GM file. The TECH 2 only loads the VIN number from the PCM, which then when connected to the SPS (Service Programming System) system it defines the correct calibration that the particular VIN needs, then it loads that calibration into the TECH2 for downloading into the PCM. I know of now way to extract that GM file from the PCM. Or to extract it from the SPS system in a raw BINARY format.
The only way is with a specific tool such as TunerCats OBD2 tuner software which is soon to be publicly released. It reads the file from the PCM for editing via the Tuner tool. Cost will be around $380 which includes one PCM definition, software and hardware. Currently there now definition for the 96 Vortec truck PCM, a 97 is in the works now 98, 99 and 00 Vortech definitions are working but limited. I am beta testing these now along with LS1 car and truck variants.
