I'm having problems getting my car tuned, it is a 99 but the guy said it could have the 98 pcm in it. I got these numbers off my pcm if anyone could tell me what pcm this is that would be great. And yes I've used the search and couldn't find anything in the pcm diagnostics section.

09386530 & 12206871

I'm thinking this is the later pcm but I need some folks to let me know for sure that know the part numbers.

Thanks, Ricky.

98 pcm's are sorta oval shaped, later are rectangular

pretty sure it is a 12200411 PCM (Serv #) and the 09386530 is the OS number

this is the same PCM that runs a LS1 engine so would be 99 onwards

+1 it is a 12200411 PCM.
If your tuner doesnt know the physical difference between a 98 and a 99+ pcm RUN!
find another tuner.

Lol he never looked at my pcm guys. He just hooked his programmer to it and it wouldn't load a tune to it for some reason, he said I probably need to have it reflashed, said they have that problem all the time.
He's also using SCT to tune it, what ya'll think of that? Have any of ya'll used that to tune gm. I know they're big into ford but are moving towards gm. By the way the place that is doing this is like big into building mustangs, i know i know. lol but they are 15 minutes from me and have dynos and all so its convenient.

has it been tuned before?. SCT used to read a custom OS that has been put in by HP Tuners, but after one of their "forced" updates they disallowed the reading and flashing of a "unknown" Operating System. Maybe thats what is up?
