I am going to be working on 1999 Cadilac Deville. Does anyone know what model computer is in that vehicle? Does EFI work on it also?

It's a Siemens PCM, we don't support them.

The 99 PCM is a Delco. It looks like an old 97 LS1 PCM. It uses 2 Mot CPU's and 4 small memory chips and a knock module.
I can write this, but I can't read it yet. :bad:

Wow, is that thing still HC11 based or is the main CPU on the other PCB? This is old 16bit stuff in there.
Hey I am in Rock Hill SC now and I have my other camera now and I can take pictures now. My old camera got broke by a valet attendant in Chicago.
I will go pop some clean pictures like the one above.
the old Delco Chip isn't always a Delco Chip. I think on different year PCM's it's a Mot

BTW it is nice to have a camera without a broken screen :rockon:
Correct, any chip that has the number '185' on it is a Motorola sourced part, anything with '466' is Delco.Quote:
