Hey guys, looking to get an ls1 powered car soon. Just wondering before i pull the trigger on one, is there any disadvantages to the 98pcm vs the later years? I know the 97gtp i have now has a completely different pcm than 98-03 and it sucks. I don't want to be in the same boat in an fbody.

 

The 99 is much better (and faster for datalogging) than the 98.
The 2000-02 is better than 99 but just a little, the 99 PCM will work just fine.

 

You've got a great comparison there. Just like the 97GTP sucks, the 98 fbody is equally (un)desirable. Stick to 99-02.

 

Thanks for the info guys!

 

rule of thumb........... first year of a generation always sucks!!!


82 Fbody crossfire injection WTF
84C4 Crossfire injection.... again WTF
97GTP
98Fbody

You guys are haters! lol Very little difference between the years though actually, but the 98 PCM's are different.
