    UGH! need to squash SFI/batch fire argument

    Pretty simple question....

    *disclaimer* I dont believe this is true but cant find docs to back it up

    Does all GM ECM/PCMs drop SFI above ~3000 rpm and switch to batch fire?

    Im certain its a big NO but again, no docs to back it up.

    *edit* did not specify but meant if the ECM/PCM is SFI

    Thanks!
