I've got a question about PID availability on different models of the same style PCM, Gen III LS1 99-08, in this example.
Here is the scenario:
A friend of mine had a 2000 Silverado with an LQ4. It was running the stock OS, 09381344. We installed an electric fan, then he decided he wanted to try lean cruise on it. We flashed the OS to 12212156, which is a 2002 Silverado with an LQ4.
I have a 2002 Z06 that is running the stock OS, 12212156.
Here is what I've encountered:
When logging his truck, I only have the option for Injector Pulsewidth Bank 1 yet not bank 2. On my Corvette, I have the option for both banks.
When logging his truck, I can log VE lookup. On my Corvette, I have a calculated VE PID, but not the lookup.
I'm curious as to whether this is hardware or software driven since we're running the same version OS, albeit for different vehicles. I'm sure there are other difference, but these are the two that I can recall from memory.
Does anyone know?
Edit:
I apologize, but this may be posted in the wrong section. Perhaps in GenIII or Scanning?
