    Default Is there a COS for a 98 pcm yet?

    I noticed HP tuners has one so I figured I better check here to see if EFILive has one before I go through the trouble of repining my harness and swaping pcms. My twin turbo project is rolling along a little faster then I though so I'll be tuning before I know it!

    I don't believe there will be one. Going to a newer PCM is a better idea anyway.

    The reason EFILive doesnt is because the 99-04 512kb PCM is much more capable than the 97-98 LS1 PCM. It is worth the few hours repinning the harness and copying the base tables over, especially when you go with a FREE COS.
